2.1 IntroductionThis section describes how to operate the 18 Series Thermal Transfer Printer in a safe manner.

Topics covered in this section include:

• Machine Safety• Safety Regulations• EMC• Electrical Safety• Electrical Safety Testing• Static Electricity Protection• General Guidelines• Isopropanol Safety• Misuse

m® 2-1Series 18 10/07

SECTION 2 - SAFETY

2.2 General Guidelines

1. ALWAYS disconnect the power to the machine before removing any cables, covers or removing the printer from the host machine.

2. DO NOT operate the machine with any covers removed. All covers must be in place using the appropriate number of fasteners.

3. All cables should be secured to the host machine to avoid any tripping hazard or entrapment by moving parts.

4. Care should be taken when operating the Model 18i without a platen.

5. DO NOT insert body parts into the printhead opening whilst the printer is powered as there is a danger that the mechanism will move without warning and present a mild crushing hazard.

6. Ensure all reasonable safety precautions have been undertaken. However, please ensure that when working with / or around the machine, every care is taken to avoid potential hazards. ALWAYS take great care around the machine not to slip, trip or fall. Especially if the machine is used in areas where the floor may be wet or greasy.

7. When removing the printer from the host machine, care should be taken to first ensure that the body of the printer is at a temperature that can be comfortably handled.

8. Safety shoes should be worn when installing or removing the printer body from packaging machinery. These units are heavy and there is a danger of injury if dropped.

9. MARKEM cannot guarantee the safety and / or suitability of non-MARKEM print ribbon. The standard certification may be compromised if non MARKEM ribbon is used.

10. If non-MARKEM ribbon is used, it is recommended that anti static properties be considered.

11. Please read the Isopropanol Safety Data Information prior to using Isopropanol with any MARKEM product.

12. There is a non-replaceable lithium battery mounted on the control board assembly. Under no circumstances should this be replaced (it should last for the lifetime of the printer).

m®2-2 Series 18 10/07

SECTION 2 - SAFETY

2.3 Machine SafetyThe product is designed to conform to all appropriate EU Machine Safety Regulations.

All relevant Safety Procedures must be followed.

WARNING: Failure to do so may invalidate the warranty.

Please read through this section before any operation of the machine is undertaken.

2.4 EMC ConsiderationsTo maintain the integrity of the EMC precautions taken with the 18 Series Thermal Transfer Printer. Any additional wiring or modifications should include appropriate EMC precautions.

m® 2-3Series 18 10/07

SECTION 2 - SAFETY

2.5 Electrical SafetyThis printer is designed for use with supply systems that conform to IEC 664 light industrial / domestic installation category II mains supply and must be appropriately earthed.

2.5.1 Recommended cable protection:

Fuses

• Use 10A HRC or HBC types with a minimum of 95A RMS symmetrical prospective current rating at a 10ms minimum pre-arcing time e.g. ASTA certified to BS88 part 2 ‘pull cap’ type or equivalent.

CAUTION: For continued protection against risk of fire, only replace the fuse with the same type and rating.

If the DC supply fuse (located on printer PCB) is replaced it must be replaced by an HBC Style ceramic fuse with the rating shown as ‘F5AL250V’.

If the AC supply fuse (located on the power supply inlet connector) is replaced it must be replaced by an HBC Style ceramic fuse with the rating shown as ‘T5AH250V’.

MCB

• Use 10A HRC or HBC types with a minimum of 95A RMS symmetrical prospective current rating at a 10ms minimum pre-arcing time e.g. ASTA certified to BS88 part 2 ‘pull cap’ type or equivalent

• MCB (Miniature Circuit Breaker): to IEC 947-2 / EN 60947-2 and BS EN 60898 with a minimum instantaneous release response current of 10x rated current (type D)

2.5.2 Electrical safety testing (after installation)It is essential that the continuity of the protective bonding circuit and the prospective short circuit current level be checked after the machine is installed and the electrical connections, including those to the power supply are complete. A competent person must carry out these tests.

• Failure to carry out these tests will potentially result in an unsafe installation and the equipment fault-clearance capability may not function correctly.

2.5.3 Static Electricity ProtectionExcessive Electro Static Discharge (ESD) around the printhead area can cause damage to the SmartDate printhead and printer circuitry.

Static reduction methods should be installed where static is seen to be a problem. Common areas of static build up are the print platens, substrates and conveyors.

Methods such as carbon brushes on the substrate, earthed conveyor frames and printer brackets, robust mains earthing and de-ionising guns are commonly used.

m®2-4 Series 18 10/07

SECTION 2 - SAFETY

2.6 Isopropanol SafetyMARKEM can supply Isopropanol wipes for cleaning the Thermal transfer printheads. Some general safety guidelines for using Isopropanol follows:

Handling

Use only in well ventilated areas. Do not breathe vapours or spray mist. Avoid contact with the skin and the eyes. When using do not eat, drink or smoke.

Storage

Keep in a cool well ventilated place. Keep product and empty container away from heat and sources of ignition. Take precautionary measures against static discharges.

m® 2-5Series 18 10/07

SECTION 2 - SAFETY

2.7 Use outside the specificationThis manual provides information about Safety, Installation, Operation, Troubleshooting and Preventative Maintenance Procedures.

3.3 Installation of the 18 Series Thermal Transfer PrinterFirst time Installations should be carried out by a qualified MARKEM trained service technician.

Please read all of the relevant safety instructions before commencing with any installation work.

WARNING: Failure to do this will invalidate the machine warranty. and is potentially unsafe.

3.4 Installation RequirementsEnsure that these services and control signals are available:

• Power - ~ 100 - 230V (+/- 10%) 50 - 60 Hz • A Print Go Signal - This can be either a volt free contact which closes when

printing is required, or a 24 V DC signal from a PNP sensor (positive edge triggered).

• Encoder (Model 18c) Single channel, 500 pulses per revolution. • In cold environments it may be necessary to wait 20 - 30 minutes after power

up before running production. This allows the printhead to warm to the necessary temperature to achieve acceptable prints. Alternatively production can be started immediately, but the first few print may not be at an acceptable standard.

m® 3-3Series 18 10/07


3.5 Bracket InstallationBracket Installation requirements vary from one customer site to another and one packaging machine type to another. Various bracket options are available to suit the requirements of specific packaging machine types.

The 18 Series Thermal Transfer Printer will normally be supplied with the appropriate bracket to suit customer machinery requirements. Please consult the documentation supplied with the bracket for assembly and installation instructions.

Figure 3–1: Intermittent Bracket

Figure 3–2: Continuous Bracket

m®3-4 Series 18 10/07


3.6 Locating Print Body and Print AnvilThe mounting and dimensional requirements of the Printer Body are shown at the rear of this manual. Additional space is required to interconnect cables.

Mounting pads are provided on three sides of the of the printer unit. These have 2 M6 holes for attaching the mounting plate provided with the unit. This plate has 4 M5 x 20mm tapped holes for fixture to the MARKEM bracket.

CAUTION: Ensure that the correct length screws are used.

The required print position on the substrate determines the position of the Printer Body. Further small adjustments to the print can be made using “Offset” settings via the Local User Interface.

Rigid fixing of the printer body is essential to achieve the best possible print quality. If vibration can be transmitted to the 18 Series Thermal Transfer Printer, the print quality may be affected.

MARKEM brackets are machined to very accurate tolerances, so that when assembled with the printer in position, the printhead to print anvil distance is correct.

MARKEM recommend this distance is between 1.00 mm to 3.00 mm.

Under normal circumstances no adjustment is necessary.

With non MARKEM brackets we cannot guarantee the accuracy of the components and would therefore recommend that the printhead gap is checked after assembly. Do not use metal objects to test the gap distance, use only wood, plastic or other non-conductive, non abrasive materials.

m® 3-5Series 18 10/07


3.6.1 Printhead AlignmentThe printhead is self aligning to a limited amount, but always ensure that it is square to the platen / roller.

3.7.6 Print Go Input Wiring

Print Go Input using a voltage free contact (A)

If a voltage free contact (X) is used it should be wired between terminals 1 (24 V DC) and 2 (PRINT GO). 18 Series Thermal Transfer Printer is edge triggered and prints whenever the contacts close. Printing can not occur again until the contacts have re-opened.

Print Go Input using a PNP sensor (B)

If a PNP sensor (A) is used connect as follows:

• Power cable to terminal 1 (+24 V)• Signal cable into terminal 2 (PRINT GO) • Ground cable into terminal 3 (GND)

18 Series Thermal Transfer Printer prints each time the sensor changes from low state to high state.

The Print Go signal can be set to use the falling edge of the signal by configuring the setting at the user interface.

The input draws a maximum of 13 mA at 25 VDC.

3.7.7 Fault and Warning Outputs

Fault - (Problem)

Pins 4 and 5 on the 7 pin I/O connector are the open relay contacts for FAULT.

Fault relay contacts open when 18 Series Thermal Transfer Printer is:

• In READY mode.• Not in a position to print because of a PROBLEM

Warning

The Warning relay contacts open when a warning such as a low ribbon condition is detected.

Pins 6 and 7 on the 7 pin I/O connector are the closed relay contacts for Warnings.

The contact is closed when the printer is ready to print.

CAUTION: The relay contacts are suitable for a current between 10mA and 1A. The maximum rating is 1A at 30VAC/DC. Control of higher voltages (e.g. 100VAC) or currents must use intermediate external control relays or contactors.

m®3-12 Series 18 10/07


3.8 Encoders (Model 18c only)

For continuous printers, an encoder is required to monitor the speed of the substrate.

The 18 Series Continuous printer bracket is supplied with an encoder fitted.

For customers who are not using a MARKEM printer bracket the following information is provided.

3.8.1 Optional EncodersIt is essential that the encoder measures the speed of the substrate at the point of printing.

The encoder should be mounted so that the wheel of the encoder is running against the print roller.

The Encoder setup can be configured from the Engineering Mode Settings menu screen.

18 Series Thermal Transfer Printer requires the encoder to provide:

• Between 2.8 - 150 pulses per mm of substrate travel.• The output connects to an NPN open collector output, operating at 24 V DC.

3.8.2 Encoder ResolutionThe encoder resolution is expressed in pulses per mm and can be set to between 2.8 pulses / mm and 150 pulses / mm.

The standard 18 Series Thermal Transfer Printer encoder has an idler wheel of 52.5 mm mounted on a 500 pulses per revolution encoder. This gives an encoder resolution of 3.05 pulses / mm.

3.8.3 Encoder SetupTo check that the encoder is configured correctly select an image of a known length. (supplied image number 99 is 40 mm) Print the image and then measure the image to ensure that the length is as it should be.

m® 3-13Series 18 10/07


3.8.4 Loading a New RibbonFollow this procedure:

If necessary release the ribbon tension.

1. Fit a new waste take up core and load a new ribbon following the web pattern on the rear of the user interface.

2. Ensure that there are no creases in the ribbon by rotating the take up reel by hand.

3. Ensure that the ribbon is tracking parallel on the rollers and is positioned correctly. The ribbon must be loaded so that it is only in contact with the movable parts of the rollers.

4. Ensure that the ribbon is wound forward enough so that the transparent or metalized lead section is not under the printhead.

5. With installations where access is restricted, the plastic forceps supplied with the machine can be used to assist with webbing the ribbon.

3.8.5 Re- Connecting a Broken RibbonIf a ribbon break occurs the following procedure should be used:

1. De-energise the motors by using the Release Ribbon function.

2. Do not tie a knot to re-connect the ribbon.

3. Wind the remaining waste ribbon onto the waste core.

4. Pull some of the unused ribbon from the ribbon supply and wind it onto the waste ribbon take up.

5. Turn the waste reel by hand at least one revolution and keep the join between the two as flat as possible.

WARNING: Failure to follow this procedure may cause unacceptable eccentricity on the waste ribbon take up reel. This cannot be controlled by the printer and may produce ribbon tension problems.

m®3-14 Series 18 10/07


3.9 Print PositionThe print position can be split into two parts:

• Registration • Print Offset

Registration is the position of the print relative to the direction of the substrate.

This can be used to fine tune the position of the print on the substrate.

Example:

Text

Direction of

Substrate travel

Target Box

Print position

Text

Without a registration set. With a registration set.

Increasing the registration will move the position of the print further back on the substrate.

m® 3-15Series 18 10/07


Offset is the position of the print relative to the Printhead.

This can be adjusted when narrow ribbons are being used.

With a left hand printer this is towards Dot 1.

m®3-16 Series 18 10/07


3.10 Preparing for printing

3.10.1 Power upWhen first switched ON the 18 Series will automatically calibrate the ribbon sensor and check the Tension sensor. This is done to check the ribbon diameter, ribbon tension and also the datum position of the printhead.

If there are no problems the 18 Series will display the Ready screen. To start producing, ensure that an Image has been selected and press Start.If the Calibration fails an Problem message will be displayed. Check that the ribbon is threaded correctly and try again.

If your 18 Series Thermal Transfer Printer has been installed correctly and the required image has been selected, your printer should now be operational.

3.11 Initial setup Before operating the 18 Series Thermal Transfer Printer for the first time, certain machine software settings will have to be established. These settings will vary depending on the substrate being used and the speed of printing.

The choice of operating mode as discussed in the Overview section of the manual will also have an impact on how the level of each setting is chosen.

These initial machine settings can be adjusted from the 18 Series User Interface. Full details on how to do this can be found in Section 6 of the Operator manual.

SECTION 4 - MACHINE OVERVIEW

4 Machine Overview

4.1 IntroductionThis section provides an overview of the main features of the Model 18i and Model 18c.

Topics covered in the section include:

• Models.• Main Components.• Key Features.• Print Designs.• CoLOS Create.• Image Template Files.• Principles of Printing.• Operating Principles.• Operating Modes.

4.1.1 Key Features• Efficient Ribbon Usage: 18 Series Thermal Transfer Printer automatically

controls the ribbon feed, no manual adjustment is required, minimising ribbon usage.

• Self aligning printhead: The print platen/roller does not require precise alignment to the printhead, therefore reducing the need for periodic adjustment.

• Continuous model: The Model 18c has accurate tracking of the substrate speed and sophisticated control of the printhead and ribbon feed to provide the best possible print quality.

• Reduced set up / down time: The printhead data is changed at the Local User Interface.

• High Reliability: the MARKEM experience of thermal printing and the latest design eliminates the need for complex mechanical maintenance procedures

m® 4-118 Series 10/07


4.2 ModelsThe 18 Series Thermal Transfer Printer is available in two printer types.

• Model 18i - Intermittent • Model 18c - Continuous (Left or Right Hand)The type of model required is dependent on the application.

m® 4-318 Series 10/07


4.3.1 Model 18iThis version is used with intermittent motion packaging machines and prints onto the material when it is stationary.

The Model 18i printer in this mode has a print area of 30mm x 40mm and print speed of 100 or 225 mm/s.

Model 18i uses a thermal print-head and thermal ink ribbon to print information onto materials held against a flat print platen.

Printing occurs during the dwell time when the packaging material is stationary.

4.3.2 Model 18cThis version is used with continuous motion packaging machines and prints onto the material when it is moving.

The Model 18c printer in this mode has a print area of 30mm x 40mm and print speed of 40 to 450 mm/s.

Model 18c uses a thermal print-head and thermal ink ribbon to print information onto materials held against a print roller.

The print-head is held in a fixed position and the ribbon is accelerated to match the substrate speed. The printhead is then moved to contact position where printing occurs as the substrate passes the printhead.

An encoder is used to establish the speed of the material being printed onto.

This makes it the ideal coder for continuous motion form fill and seal machines and horizontal flow wrappers.

m®4-4 18 Series 10/07


4.4 Print DesignsThe 18 Series Thermal Transfer Printer contains 100 pre-designed images.

Additional images can be designed using MARKEM’s CoLOS Create image design software and downloaded to the 18 Series via a USB storage device.

4.9 Principles of Printing

4.9.1 Thermal Transfer TechnologyThe 18 Series machines use thermal transfer printheads, similar to the ones used in Fax machines.

Thermal transfer printers can also operate without ribbon by using specially treated paper which turns black when heated. This is the way fax paper reacts.

18 Series Thermal Transfer Printers always use ribbon.

Each printhead has a series of heating elements (resistors) along the print line. These printing dots are 8 per mm and are covered in a ceramic glaze for protection.

When printing, the printhead is moved out by activating a solenoid. This causes the printhead to press the ink ribbon against the substrate or label. The heat from the printhead dots melt the ink and the pressure of the printhead against the substrate transfers the ink to the substrate.

4.9.2 Print ProcessWith the Intermittent printers, the step rate of the printhead carriage motor is in direct relationship with the linear motion of the carriage.

The length of time that the dots are energised for is determined by the linear speed of the printhead carriage.

With the Continuous printers, the length of time that the dots are energised is determined by the speed of the ribbon, which in turn is controlled by data from a speed encoder.

The print control processor determines which dots to energise and when to activate them.

In both cases the length of each dot should end up at 1/8 mm to maintain the aspect ratio of the character being printed.

m®4-10 18 Series 10/07


An example of how this works is shown below:

If an Intermittent printer were to print the following sequence:

• Dots 1 to 12 are energised three times relative to the linear speed of the print carriage.

• Dots 4 to 8 are energised eighteen times relative to the linear speed of the print carriage.

• Dots 1 to 12 are again energised three times relative to the linear speed of the print carriage.

If a Continuous printer were to energise the dots in this sequence it would be relative to the ribbon speed.

In both cases the printed image would then look as follows:

Step 1

Step 26

Step 4

Step 23Step 24

Step 3

PRINT

Direction ofPrint

12 dots = 1.5mm

The resulting character may then be part of the design text or a part of a Graphic or a Logo. This process happens extremely fast and the printed character may only take a fraction of a second to print.

For example:

The above character is represented as 26 steps long, just over 3 mm. If the print speed were 100 mm/sec, this character would only take approximately 3/100 of a second to print.

m® 4-1118 Series 10/07


4.10 Operating PrinciplesThe two printer types use different methods of operation specifically designed to suit the running methods of the packaging machines being used.

The Model 18i uses a thermal printhead and thermal ink ribbon to print information onto materials held against a flat Print platen.

The Model 18c uses a thermal printhead and thermal ink ribbon to print information onto materials held against a Print roller.

Intermittent with Print Platen Continuous with Print Roller

4.11 Standard Mode OperationThe 18 Series Thermal Transfer Printer transfers ink from the ribbon directly onto the substrate by means of a thermal transfer printhead. In this mode the ink removed from the ink ribbon will be equal in size to the printed image on the substrate.

For example, a 2 mm long print will use 2 mm of ribbon.

This is the normal running mode for 18 Series Thermal Transfer Printer and will usually achieve the best print quality results.

Certain conditions will determine the standard of print quality achieved:

• The Substrate material being used• The type of Ink Ribbon being used.• The Speed at which printing is performed.• The Printhead pressure setting.• The Printer parameter settings• The gap between the printhead and roller or platen.• The correct combination of all of these will greatly improve print quality.

m®4-12 18 Series 10/07


4.11.1 Print Cycle Model 18iThe Model 18i has a print area of 30mm x 40mm and print speeds of 100 or 225 mm/s.

The Model 18i prints when the substrate or label is stationary.

The printhead is moved out during the dwell time of the packaging /labelling machine, and then moved across the substrate / label while printing takes place.

The Intermittent model advances the ribbon during the return movement of the printhead. The ribbon is only advanced by the same amount as it prints plus a small margin to prevent images overlapping.

For example, if the image is 25mm long, the ribbon is advanced by 26 or 27 mm. This keeps ribbon waste to a minimum.

The Model 18i can print Text, Bar codes (bitmaps) or Logos at any position within the 30 mm width by 40 mm length print area.

The operating sequence is:

1. A Print Go signal triggers the print delay timer.

2. The print delay elapses and the printhead moves into position.

3. The printhead moves along a linear slide and prints the required information.

4. The printhead retracts.

5. The printhead returns to its home position and the ribbon moves along ready for the next print.

The 18 Series Thermal Transfer Printer is now ready for the next print sequence.

m® 4-1318 Series 10/07


4.11.2 Print Cycle Model 18cThe Model 18c has a print area of 30 mm x 40 mm and print speeds of 40 to 450 mm/s.

The Model 18c prints while the substrate is moving.

In this case the printhead only moves out to the print position and has no linear motion.

A shaft encoder is used to track the substrate speed.

The ribbon speed is accelerated up to match the substrate speed before printing can occur.

This is done by means of two stepper motors.

The Model 18c can print Text, Bar codes or Logs at any position within the 30 mm width by 40 mm length print area.

This makes it the ideal coder for continuous motion form fill and seal machines and horizontal flow wrappers.

The operating sequence is:

1. A Print Go signal triggers the Print cycle

2. The encoder signal determines the speed of the substrate.

3. The ribbon is accelerated to match the substrate speed.

4. The printhead is moved to the print position.

5. The required information is printed. (The printhead has no linear motion).

6. The printhead retracts and the ribbon is returned ready for the next print.

The 18 Series Thermal Transfer Printer is now ready for the next print sequence.

Ribbon Status Indicator

The Ribbon Indicator is positioned at the left of the screen.

The ribbon Indicator is followed by a gauge made up of 10 increments with a bar to indicate the extent of the gauge.

The span of the horizontal bar below the vertical bars indicates the maximum ribbon capacity of the printer.

(MARKEM 3810 ribbon 450 Metres)

If you load a new 450 metre ribbon the gauge will indicate full capacity.

This is recorded when the ribbon is calibrated.

If a partly used ribbon is loaded the same procedure is followed and the gauge adjusted accordingly.

This gives the user an indication of how much ribbon is remaining.

7.1 IntroductionThe following section provides general advice for ensuring that your 18 Series Overprinter is working at its most efficient.


• Printhead Gap• Print Platen• Ribbons• Printer Settings• Print Signals• Print Quality Issues• Moving the printed image• Timing Issues

m® 7-118 Series 10/07


7.2 Setup Issues

7.2.1 Print AnvilThe print roller for Model 18i and print platen for Model 18c are wear parts, and should be checked regularly for damage.

If the print roller has become damaged this will cause print quality problems. For example a flat spot on the Model 18c roller rubber will appear as a repeated blank area on the Test pattern. A worn area on the Model 18i print platen rubber may cause the print to be faded on one side.

7.2.2 Printhead GapThis is the distance between the printhead in its home position and the contact point on the substrate.

Do not use metal objects to test the gap distance, use only wood, plastic or other non conductive non abrasive materials.

Adjustment to the print gap can be made by using the adjustment screw provided with the mounting bracket. The gap between the printhead and the print platen or print roller is critical to the performance of the printer.

The following settings are recommended:

Model 18i - 1.00 mm - 3.00 mm

Model 18c - 1.00 mm - 3.00 mm

Note: The printhead pressure setting is associated with the amount of printhead gap. The smaller the printhead gap, the more printhead pressure required.

7.2.3 RibbonsThe 18 Series uses inside or outside wound ribbon; If this is webbed incorrectly (wound the wrong way around) no printing can occur. Ensure that the ribbon is webbed correctly around the print roller. (See webbing diagram on the rear of the User Interface) The correct substrate/paper to ribbon match is also important for print quality.

Different conditions will require different types of ribbon.

Some examples follow:

Wax/Resin, Wax/High Resin and Resin

For full details on ribbon please contact you local MARKEM representative or visit the MARKEM Web site.

m®7-2 18 Series 10/07


7.3 Important Printer SettingsVarious Printer Settings will affect the performance of the 18 Series printers.

The initial setup of the machine would normally be performed by a qualified MARKEM trained technician, but if not the following information should prove helpful.

7.4 Print Darkness

The print darkness is adjusted by varying the amount of time heat is applied for each row of dots printed and altering the amount of cooling time allowed between rows.

Generally, increasing the Darkness darkens the printing but can increase smudging. Conversely, decreasing the Darkness reduces smudging. Some ribbon/substrate combinations may require a Darkness other than the standard 100.

The 18 Series automatically limits the amount of energy transferred to the Printhead. This prevents the head being damaged by incorrect use of the darkness value. If the print quality is not good refer to the Troubleshooting Section for diagnosis.

Print darkness levels should be set in relation to the print speed.

• For example, if the print speed is high, the print darkness may have to be raised to achieve good print quality.

• If the print speed is lowered the print darkness should be reduced accordingly.• As a general rule darkness levels should be kept as low as the line speed and

print quality requirements will allow This will ensure that the print-head life will be used to its optimum.

• Darkness levels that are too high may also contribute to poor print quality or ribbon breakage (especially when printing bar-codes or horizontal lines.)

• The maximum darkness level for any print speed is 150%. The 18 Series automatically compensates for this if the print speed is raised or lowered.

• If a printhead dot has become damaged and no replacement printhead is readily available, raising the darkness level may be enough to spread the heat to effectively close the gap. This would allow the printer to be used until a new printhead has arrived.

Note: The darkness level should be reduced when the new printhead is fitted.

m® 7-318 Series 10/07


7.4.1 Print SpeedThe speed that Printhead moves along the linear slide (Model 18i).

The speed the ribbon moves on the print part of the cycle. (Model 18c)

With Intermittent printers the speed is determined by the dwell time when the substrate has stopped moving.

• If the print speed is set too low the substrate may start to move before printing has finished.

• If the print speed is too fast the print quality may not be as good as it could be.• With Continuous printers the speed is automatic as an encoder is used to

match the speed of the substrate.• The ribbon speed has to match the substrate speed before printing can occur.

If the substrate speed is too high or too low this will affect the print quality.

7.5 Print Signal Issues

7.5.1 Debounce Time This is the time that the PRINT GO signal must be present before it is actioned. This avoids double triggering of the print signal if the signal is particularly noisy (e.g ringing on a relay contact)

If the signal used is arriving as a double pulse, set the Debounce time just high enough to stop the printer double printing.

The print signal is sampled every 5 milliseconds, so if the Debounce Time is set to 10 milliseconds, the Print Signal must be at least 15 milliseconds.

7.5.2 Print Delay With the Model 18i Intermittent printers, this sets a delay between a valid PRINT GO signal and when the Printhead is moved out into position.

If the PRINT GO signal is received before the substrate is stationary, this allows time for the substrate to settle before printing commences.

Set the print delay setting as low as possible as it increases the overall cycle time of the printer.

Default - 0 ms

m®7-4 18 Series 10/07


7.6 Moving the Printed ImageThe position of print within the printing area can be changed. Altering the Registration and Offset values moves the printed information in the head feeding direction and up and down the Printhead.

On intermittent printers, when the Registration is altered the printhead will move to its new datum position immediately and will use this new datum until the Registration is altered again.

7.6.1 RegistrationIt is possible to move the print image down the print area.

This ability is useful if small movements are required.

CAUTION: If larger position changes are required this method may not be suitable.

For example, on a Model 18i, if you have an image length of 30 mm and you move the image down the printhead by 15 mm, then that gives you a total length of 45 mm. The maximum print height is only 40 mm, so you will miss the last 5 mm of the image.

When selecting the Image, if the amount of registration plus the image is too long, you will get a warning message. You can press “Hide” to clear this warning, but you should reduce the value or the image height before proceeding.

7.6.2 OffsetThis allows fine adjustment of the print position across the printhead.

This ability is useful if small movements are required.

CAUTION: If larger position changes are required this method may not be suitable.

For example, It is possible to move the print image off the side of the ribbon and printhead.

If you have an image width of 20 mm and you move the image across the printhead by 15 mm, then that gives you a total width of 35 mm. The printhead is only 32 mm in width so you will only print the first 17 mm of the image, leaving off 3 mm.

m® 7-518 Series 10/07


7.7 Timing issuesMany timing issues (speeding up the line/host machine) can arise when setting up a new application, or when changing the way an existing application works. Timing issues can be common to the Model 18i and Model 18c. Since the machines work differently, it is likely that timing issues will vary with the machine type.

7.8 Distance between prints on the ribbonTwo things can affect the distance between each print on the ribbon.

• If the substrate accelerates or decelerates between the end of the registration and the start of print, the gap will be affected.

• When the printer adjusts the ribbon tension the gap will be affected.

7.9 Distance between prints on the substrateWith Intermittent printers the distance between the prints is set by the stopping position of the substrate or labels.

With Continuous printers several things can affect the “minimum” distance between the prints on the substrate:

• The amount of registration set after the Print Go signal.• The Debounce distance.• The Head down and Head up time.• The Return speed of the ribbon.

The Model 18c printers always allows the substrate to move a set distance after receiving a Print go signal. This distance is the same no matter the speed of the substrate.

After this distance the printhead has been lowered ready to print.

This ensures the printed image does not drift from the required position on the substrate.

8.2 The 18 Series Thermal Transfer PrinterThe 18 Series Thermal Transfer Printer is the unit that contains all the printer mechanics together with the control electronics.

Two distinct versions of the printer are available:

Model 18i - Intermittent Printer

Model 18c - Continuous Printer

The Continuous model is available in left or right hand versions.

The Intermittent print module is mounted onto a linear slide and the Continuous printer module is mounted onto a fixed mounting plate.

8.3.1 Intermittent Drive System - Model 18i PrinterThe intermittent version of this printer requires the printhead to move over the substrate while printing occurs.

The printhead module (A) is driven backward and forward along a linear slide (C) by means of a printhead carriage (B) that is connected to the drive belt.

The printhead module is mounted on this carriage and is secured by four screws.

The linear slides are supplied with a linear ball bearing carriage which provides a smooth motion for the assemblies.

A stepper motor is used to drive a toothed drive belt (D) around two geared pulley's, (E) one of which is used to tension the belt.

Two other stepper motors are used to control the ribbon drive system.

Printing occurs while the substrate is stationary. I

8.3.2 Continuous Drive System - Model 18i PrinterThe Continuous version of this printer does not require the printhead to move over the substrate while printing occurs.

The print module (A) is mounted onto the print carriage (B) the same way as for the Intermittent version of this printer, but this is then fixed onto a rigid mounting block (C).

The printhead module is held in a fixed position and has no linear motion.

Printing occurs when the substrate is in motion.

D

(A) Ribbon Take up Reel

(B) Ribbon Supply Reel

(C) Ribbon Movement Roller

(D) Ribbon Tension Roller

The ribbon drive is a direct drive system and does not require the use of a clutch. This is achieved by the use of two stepper motors.

The stepper motors are connected to the ribbon supply and waste take up spools. This gives the printer the ability to drive the ribbon accurately in both directions. The drive system requires no setting up and therefore alleviates the possibility of incorrect torque being used.

The ribbon is routed around a movement roller and a tension roller. When operating these supply data to a microprocessor via hall effect sensors.

The 18 Series firmware uses an algorithm to calculate the amount of tension required for the ribbon and adjusts the stepper motors accordingly.

m®8-6 18 Series 10/07


8.4 The Printhead ModuleThe 18 Series print module is designed to be used on all versions of the 18 Series printers. The modular design means that it can be used for both Intermittent and Continuous versions of the printer. The module can also be easily changed from a left hand to a right hand version. (L) and (R)

The print module (A) houses the spring loaded quick release mechanism (B) for printhead movement. The printhead assembly (C) is connected via an adapter plate (D) to the this mechanism.

8.5 Printhead AssemblyThe printhead assembly is designed for easy removal and replacement.

The assembly plate is attached to the printhead by two 3 mm dowel pins and two 3 mm cap head screws.

The complete assembly can be detached from the print module easily by undoing the quarter turn spring loaded screw mechanism behind the printhead. The printhead assembly can then be removed.

The printhead resistance level is shown on the label attached to the printhead.

8.5.1 Printhead Voltage ControlThe printhead voltage is electronically adjusted under processor control.

The resistance level of the printhead is entered at the Local User Interface.

Menu - Print Settings - TPH Resistance.

m® 8-1118 Series 10/07


8.6 Printer OrientationIt is critical to the success of the printer that all parties understand the orientation of the printer.

With Model 18i printers, the substrate is stationary when being printed onto and the only issue here is access to the printer. Intermittent printers are therefore Left Hand only.

The Model 18c printers can be Left or Right hand orientated.

The decision to select a right or left hand printer will depend on the direction of the substrate.

With Continuous printers the print-head angle must always be in the direction of travel of the substrate.

The rule for determining the printer hand is as follows:

m®8-12 18 Series 10/07


Left Hand Printer showing: Angle of the Printhead.Direction of the Substrate travel.

Right Hand Printer showing: Angle of the Printhead.Direction of the Substrate travel.

If the Model 18c is to print from the underside of the substrate, and access to the printer is to face in the same direction, the opposite hand would be required.

Alternatively the same hand could be used but access would have to be from the opposite side.

Right Hand Printer showing: Angle of the Printhead.Direction of the Substrate travel.

Left Hand Printer showing: Angle of the Printhead.Direction of the Substrate travel.

m® 8-1318 Series 10/07


8.7 Printer CalibrationThe Model 18i printer calibrates on power up or if the ribbon has been removed and replaced.

This is done to check the diameter of the ribbon and the ribbon tension.

m®8-14 18 Series 10/07


8.7.1 Ribbon Movement CalibrationBoth Intermittent and Continuous versions of the 18 Series Thermal Transfer Printer require the ribbon drive to be calibrated.

Ribbon calibration is performed by running the two ribbon drive stepper motors.

This in turn drives the ribbon round a movement roller which has a 2 pole magnet on the end of it.

The ribbon sensor input is connected to a Hall-effect sensor mounted in the printer base plate.

The printer electronics detect the rotation of the magnet.

This signal is then analysed by the firmware to establish the diameters of the ribbon supply and take up reels.

Ribbon tension is then adjusted by stepping the two ribbon drive motors independently at the required ratio.

m® 8-1518 Series 10/07


8.7.2 Ribbon Movement RollerThe ribbon movement roller (A) has a high friction coating and has a 2 pole magnet (B) on the end. The roller is fitted with bearings (C) and mounted into a housing unit (D). This unit is then fitted onto the base plate of the printer.

With the roller in position it is located next to a Hall effect sensor (E).

As the roller and magnet rotate, the magnetic field strength varies.

Data is gathered by the Hall effect sensor and analysed by the processor.

This used to control the ribbon drive.

Information such as ribbon breaks or remaining length of ribbon are controlled from this data.

8.7.3 Ribbon Tension RollerThe ribbon tension roller is used to help maintain a constant tension on the ribbon.

The roller is mounted onto a sprung and pivoting dancing arm mechanism (A).

At the opposite end of the mechanism are two magnets(B).These are positioned either side of a Hall Effect sensor (C). The magnetic field strengths are measured between each print. The data from this sensor is then analysed by the processor and the stepper motors are adjusted accordingly.

8.8.1 Stepper Motors The 18 Series Thermal Transfer Printers use three stepper motors, one to drive the carriage for the printhead module and two for control of the ribbon.

The 18i uses three stepper motors and the 18c two stepper motors.

The position of the stepper motors is the same for all models of the 18 Series.

The stepper motors are four wire motors connected in a unipolar configuration.

The motors are connected to the printer board via 4-way 2.54 mm Molex KK connectors.

Connection points:

• J7 - Ribbon motor 1 (Supply LH Printers)• J8 - Ribbon motor 2 (Take up LH printers)• J9 - Carriage Motor (Intermittent Printer)

When the printer is in Intermittent mode the printhead carriage motor steps are in direct relationship to the linear movement of the printhead.

With Continuous versions of the printer the printhead carriage has no linear motion during printing.

The ribbon motors steps are configured according to data from the Ribbon roller sensor, Ribbon tension sensor and Encoder if being used.

8.8.2 EncoderThe Encoder is used in conjunction with Continuous printers.

The Encoder is used to calculate the current Substrate speed and adjust the ribbon speed to match.

The four wires from the Encoder connect into the printer through a removable screw terminal connector on the printer body.

m®8-18 18 Series 10/07


8.9 Power ConfigurationConnect the required power (90 - 260 V AC 50 - 60 Hz) to the power supply unit using the IEC lead provided. A 10 A fuse is used in the mains plug connector, or a 10 A MCB is recommended to protect the supply cable at source. The IEC inlet contains 20 mm T5AH250V ceramic fuses. The Power supply unit provides 24VDC for the Printer.

8.9.1 Mains Power SwitchThe power supply connector comprises of an On/Off switch, a IEC320 socket and a 250V Fuse holder.

Particular attention should be given to the printer body, especially if food products are able to fall into the unit.

• Turn off the power to the printer. • Clean inside the printer body. Since there are electronic components inside

this casing, DO NOT use water to clean the unit. Isopropanol cleaning wipes can be used for this purpose.

• To clean debris from the inside of the printer body, MARKEM recommend the use of a soft bristle brush.

9.2.1 Quick/Regular Checks• Check and clean printhead (daily check). • Check that the ribbon is tracking through the rollers correctly. Pull the ribbon

through by hand, and visually check to see if the ribbon is creasing across the width of the ribbon. (See Troubleshooting 10.7.3)

• Check the Peel Roller for any ink build up and clean if necessary.• Check that Darkness / Speed settings are site standard. This will ensure that

the print remains a good quality, and it may also highlight any potential problems. For example, if the darkness is unusually high, the printhead may need cleaning. The darkness has probably been set high to compensate.

• Check condition of Platen rubber (Model 18i). Clean or replace it if necessary. The platen rubber needs to be smooth, flat and free from debris. To change the platen rubber, first take the old platen rubber off. All the adhesive should be removed from the metal platen base. Replace with a MARKEM platen rubber for best results.

• Check for wear or internal debris.

9.2.2 Monthly Checks• Check condition of peel roller: Remove roller and inspect internally for wear.

Replace if necessary.• Check condition of the ribbon guide rollers: Check that bearings are smooth.• Check condition of ribbon sensor roller. Inspect the roller coating for wear and

damage. If worn or damaged, replace the roller. • Ensure all rollers are square to the Printer. • Print a test image to check printhead quality and alignment. See Section 6 -

Menus.• Check condition of printhead carriage drive belt and associated components:

pulleys, bearings, retainers and shafts.

m®9-2 18 Series 10/07


9.3 Care of the Printhead Although purpose-built for its application, the printhead is still subject to wear and tear. Careful consideration at the time of installation and regular preventative maintenance can significantly help to maximise printhead life.

The most frequent cause of printhead damage is abrasion - either from ingress of airborne particles or from an abrasive substrate surface. Consequently, printhead life varies considerably among substrate materials and among applications.

The thermal ribbon protects the printhead against wear. With use of various ribbon widths and an abrasive substrate, it is possible that the unused, unprotected, section of the printhead is subjected to wear and damage. Usually, abrasive substrates have pre-printed inks. Particularly, some red inks may be more abrasive than other colours.

Procedures for all thermal transfer printers follow:

• Regularly clean the printhead. The frequency of cleaning is entirely application and environment specific.

• To minimise printhead wear, always use the minimum pressure that delivers an acceptable print quality.

9.4 Cleaning the Printhead The printhead should be cleaned at regular intervals. These depend on machine use, operating environment, and choice of thermal ribbon.

1. Turn off the power to the controller and remove the ribbon.

2. Allow the printhead to cool to normal room temperature before proceeding in order to prevent the possibility of thermal shock damage.

3. Use a cotton swab or a soft cloth soaked in Isopropanol solvent to remove any residue from the printhead. Take care not to use excessive amounts of solvent.

The print line is located on the bevelled edge of the printhead.

Use great care not to damage the printhead during cleaning. UNDER NO CIRCUMSTANCES should abrasive materials, or tools such as screwdrivers, be used for cleaning the printhead.

Replace the ribbon and check the print quality. If the overall quality is poor, or some of the dots are not printing, the printhead may need to be adjusted or changed.

m® 9-318 Series 10/07


9.5 Replacing the PrintheadTurn off the power to the printer.

Always ensure anti static precautions are used when handling new printheads.

9.5.1 Removing the damaged printhead

When fitting a new printhead ribbon cable ensure that the black connector is fully extended before pushing in the ribbon. Secure fully after fitting.

m®9-4 18 Series 10/07


9.5.2 Setting the correct Printhead ResistanceNote the resistance value printed on the PCB side of the new Printhead. This value must be entered into the User Interface menu structure.

The processor will then adjust the voltage level to suit the particular printhead resistance level.

Each Printhead has an individual Resistance level, and the voltage level setting required for each is different. A label on the printhead displays the rating for that particular one.In this case, R = 1094

10.3 Common IssuesListed below are a number of possible faults and suggestions for possible corrective actions.

10.3.1 No Power to the Printer• Power switch must be in the ON position. This switch is located at the rear of

the power supply• Check that the mains cable is correctly inserted into the mains connector

below the switch.• Check that the mains fuse on the fuse selector is OK and replace it if

necessary.• Check the mains supply to the 18 Series Thermal Transfer Printer. There may

be another fuse or MCB installed to protect the Mains Cable at source.

10.3.2 Printhead Cables• Connectors may vibrate loose under normal operation if not correctly installed.

Loose connections may be the cause of many problems such as poor print, no print, or no power to the printhead.

10.3.3 Encoder• Check that the encoder is rotating freely. The Model 18c in continuous mode

will not print unless the encoder is moving.• Check that the encoder is sending a signal back to the 18 Series Thermal

Transfer Printer. Use the diagnostics screen to check the encoder input signals.

10.4 No Information Is PrintedIf the printer appears to be operating correctly but no data is printed, check the following:

• Is a valid image selected?• Check that the print speed and darkness values are at appropriate levels for

the thermal ribbon and substrate.• Is the printhead coming into full contact with the print platen / roller across its

full width?• Is the correct ribbon loaded with the inked surface away from the printhead. Is

it driving correctly?• Check that the ribbon is correctly webbed through the peel roller.• On continuous printers, the encoder signal may not be providing the correct

speed information.• The printhead may be faulty.

10.5 The Printhead Does Not Move OutThe Printhead in / out motion is driven by a small solenoid. If the head does not move out, use Manual mode to test the operation of the solenoid. Check the following:

• Check that the head is free to rotate in its mounting.• Check the solenoid wiring.• Replace the solenoid as required. • If the fault persists, replace the Printer PCB.

m® 10-1118 Series 10/07


10.6 Drive System Issues

10.6.1 Ribbon is not driving• Check that the ribbon cores on the supply and take up spools are not slipping.

You can see this by taking the ribbon core off and looking on the inside.• Check that the drive couplings for the ribbon drive have not come loose. This

can easily be checked by trying the coupling by hand.

10.6.2 Ribbon Drive Problems• If the print darkness is too high or the print speed too low, the ribbon can be

weakened and break. This can be eliminated by reducing the darkness or increasing the speed.

• The ribbon take up is not winding the waste ribbon correctly.• Check that there is no interference between the accumulated wasted ribbon

and any other part of the printer body. Ensure that the waste ribbon spool is gripping the core firmly.

10.6.3 Ribbon CreasingRibbon creasing is generally due to the ribbon attempting to ‘track’ across the Printhead.

The most common causes are:

• Bent ribbon guide rollers. This may occur if the printer is dropped. It is not usually possible to bend a pin back into position. Remove and replace the guide roller.

• A bent peel roller. Remove and replace the peel bar.• Poor print platen / roller alignment can in some cases cause ribbon creasing

as the substrate tries to pull the ribbon across the printhead.

10.6.4 Ribbon Breaking or Scuffing Prints

(Continuous printers)

If there are problems with ribbon breaking or scuffing prints, it is possible that the printhead gap is set too small. The printhead will move out as the ribbon begins to accelerate.The printhead will then make contact with the ribbon before it is up to speed.

• Try increasing the printhead gap.

(Intermittent printers)

The printhead may be starting to print before the substrate / labels have stopped moving. The target material must be stationary before printing occurs.

• Try increasing the print delay.

m®10-12 18 Series 10/07


10.6.5 Ribbon Coning (Continuous Printers)If there is a problem with the waste ribbon coning on the take up reel, check the following:

• Ensure that the printhead is aligned correctly with the print roller. (See Installation) If incorrectly aligned this will cause tracking problems.

• Ensure that the ribbon is tracking parallel on the printer rollers and is positioned correctly.

• Ensure that none of the rollers have been bent or damaged.• Ensure that the Printhead and Peel roller are clean. Ink deposits can also

contribute to ribbon coning.

10.6.6 Peel Roller Problems• If a peel roller is difficult to spin due to a build up of material debris between

the inner roller body and shaft, change the roller.• If the peel roller is very worn and running loose on the shaft, change the roller.

10.6.7 Head not returning to home position (Model 18i)

This problem only relates to the Intermittent printer. If the head feeds satisfactorily, but does not return to the correct home position, check the amount of registration that has been set. The printhead module will only return to the default start position if the registration is set to 0.

m® 10-1318 Series 10/07


10.7 Printhead Module Carriage Drive Problems A stepper motor, drive belt and linear slide are used to move the Printhead module carriage.

The carriage drive may stall when the 18 Series Thermal Transfer Printer is under excessive load.

If the carriage does not drive, check the following:

• Is the ribbon is loaded correctly?• Is there any mechanical interference stopping the carriage moving?• Check the condition of the drive belt and drive pulleys.• Check the condition of the linear slide. • With the power to the unit turned off, is the Printhead module free to move

along the slide?• Are the stepper motor connections correct and secure.• If the fault persists, replace the Printer PCB.

10.8 Display Issues

10.8.1 Back light only litIf the User Interface LCD screen is lit, but the text or icons are just visible check the following:

• Has the LCD contrast been set too high or low?• Adjust the contrast by pressing the button left of the 0 on the numeric keypad.• If no text or icons are visible check that the LCD connector to the printer PCB

has not become loose.• If necessary replace the Use Interface.

10.8.2 LCD only, no Back lightIf the LCD text is visible but the back light is not on check the following:

• Has the back light connector to the controller PCB become loose?• Is the wiring damaged?• If necessary replace the User Interface LCD module.• If necessary replace the User Interface PCB.

10.8.3 Display is totally blank• Check the power to the 18 Series Thermal Transfer Printer. • Check the User interface cable for damage.• Check that the LCD and Back light connectors to the User Interface PCB have

not become loose.• If necessary replace the User Interface module.

m®10-14 18 Series 10/07


10.9 Print Quality ProblemsThe most common causes of poor print quality are:

• Dirty printhead: Clean the printhead with the MARKEM Isopropanol wipes and try again. Take care not to damage the printhead during cleaning. Always allow the printhead to cool prior to cleaning.

• Dirty, worn or badly misaligned print platen / roller: Produce a full-size test print to establish the quality of the print.

• Ribbon is not driving correctly: Clean the ribbon rollers and check that the ribbon is loaded correctly.

• Excessive vibration of the packaging machine: Improve the mounting of the 18 Series Thermal Transfer Printer. If possible, increase the print delay so that vibration has reduced by the time printing starts.

• On intermittent printers, the substrate is still moving when printing starts: Increase the print delay.

• On continuous printers, the speed encoder is not providing an accurate measurement of the speed of the substrate: Adjust encoder.

• Matching of the ribbon to the substrate is very important. An improper match will not produce good print quality: Contact your local MARKEM Business Centre for further details.

• Lines of dots are not printing. If cleaning the printhead and platen / roller does not resolve the problem: Replace the printhead.

10.9.1 Faded printPrint quality is dependent on the following:

• Quality of the substrate and ribbon being used, • Print Darkness• Printhead pressure and print speed combination• Condition of the machine being used to printThe age and storage conditions of the ribbon can also affect the print quality. The printhead should be kept clean by using Isopropanol wipes. It should never be touched with any abrasive material or metallic objects.

The Test Pattern function is the best way of setting the machine print standards, such as evenness of the print; positioning of the image; and checking for damage to the dots.

Recommendations:

• Clean the printhead and platen• Increase the darkness or• Reduce the print speed• Review ribbon.

m® 10-1518 Series 10/07


10.9.2 Faded on one sideThis is generally due to a misalignment of the printer to the platen roller/ pad. The printhead will move down to print on the substrate, and will hit one side of the roller/ pad first.

Recommendations:

• Check that the printer is not loose, especially if it has just been replaced.

10.9.3 Blurred edgesThis is generally due to the darkness setting being too great.

Recommendations:

• Reduce the darkness or increase the print speed

10.9.4 Missing lines perpendicular to printheadThis is generally due to either a dirty printhead or a damaged printhead. Dirt can build up on the printhead after a period of time causing dots to be missing. If a printhead becomes damaged by physical or element damage, it can cause missing dots, see section Printhead Care.

Recommendations:

• Clean the printhead.• Use the Offset to move the image away from the damaged dots, or replace

the printhead.

10.9.5 Print rubs offThis can be for a number of reasons:

• There is not enough energy going to the printhead. This is more apparent in cold environments. Increasing the Darkness and in extreme conditions, the background energy levels of the head can make a difference to the permeability.

• In environments of high temperature and humidity, the applied ribbon may still be warm and could rub off. Trying a different ribbon grade could be the solution.

• Mismatch in ribbon/ substrate. Some substrates have coatings that make it very difficult to adhere to. The coatings may be, for example, a wax/ resin mix similar to the actual ribbon. If this is the case, then trying another ribbon grade is the best recommendation. If you are using a MARKEM Grade 3810, then try a Grade 3510 or Grade 3910. This may resolve the problem, but remember this is a resin-based ribbon that needs more energy to print, so may be limited in speed (typically to <350mm/s on polypropylene).

10.9.6 Elongated or compressed print

(Intermittent printers)

The printhead is printing on the substrate when it is still moving. Modify the Print Delay Parameter.

Depending on whether the application is printing in the same direction of the substrate or against the direction of substrate movement depends on whether you will need to increase the Print Delay or reduce it.

(Continuous printers)

Check that the encoder is not slipping on the roller.

If the Encoder setting is configured as Internal, the (Ribbon speed) Substrate speed set must match the actual substrate speed.

10.9.7 Double printing

Check the sensor/ signal source to make sure that it is not triggering twice per product. If the input is a relay, and you find that it is bouncing, then increase the Debounce Time or Debounce distance to filter out the bounce.

10.9.8 Prints occur on every other product (or less) The likely causes for this are timing issue (refer to Timing Issues, Section 7, for further details).

The print cycle may be too long:

• The overall print cycle is longer than the product to product time. The 18 Series Thermal Transfer Printer must complete its cycle before it can process the next print signal.

Either reduce the throughput of the host machine or reduce the cycle time on the 18 Series Thermal Transfer Printer. On an Intermittent printer this can be done by increasing the print speed, depending on the particular application. Also check the Debounce and Delay Time.

• Registration setting is too long (Continuous only)• This can increase the Cycle time to be greater than the product to product

time, thus only printing every other product.

10.10 Image Selection Problems

10.10.1 Selecting an Image A valid Image or test pattern must be present in the printer memory for 18 Series Thermal Transfer Printer to able to print something. This can be done by selecting a test pattern in Engineer mode. or selecting an Image by using select Image in Producing or Ready mode.

If selecting an Image, all the information must be present in the database.

Any relevant Image files or Logo files must be present.

10.10.2 Image corruption problemsImages can occasionally become corrupted. This would be noticed in the form of missing text fields on the image or not being able to select an Image.

To ensure that the images are as they should be, it is best to clear the problem image out of the 18 Series Thermal Transfer Printer and re- download the design. To ensure that no remnants of the corrupt image are left in the printer memory, select a Test Print before re-selecting the image.

10.11 Checking Database Information

10.11.1 LocalYou can check whether the Image is present in the local memory by scrolling through the database using Image menu. If the Image is not visible then it is not present.
