IIMPORTANT SAFETY NOTICES PREVENTION OF PHYSICAL INJURY

1. Before disassembling or assembling parts of the printer and peripherals, make sure that the printer power cord is unplugged.

2. The wall outlet should be near the printer and easily accessible. 3. Note that some components of the printer and the paper tray unit are

supplied with electrical voltage even if the main power switch is turned off. 4. If any adjustment or operation check has to be made with exterior covers off

or open while the main switch is turned on, keep hands away from electrified or mechanically driven components.

5. The inside and the metal parts of the fusing unit become extremely hot while the printer is operating. Be careful to avoid touching those components with your bare hands.

HEALTH SAFETY CONDITIONS

1. Toner and developer are non-toxic, but if you get either of them in your eyes by accident, it may cause temporary eye discomfort. Try to remove with eye drops or flush with water as first aid. Get professional medical attention.

OBSERVANCE OF ELECTRICAL SAFETY STANDARDS 1. The printer and its peripherals must be installed and maintained by a

customer service representative who has completed the training course on those models.

2. The NVRAM on the system control board has a lithium battery which can explode if replaced incorrectly. Replace the NVRAM only with an identical one. The manufacturer recommends replacing the entire NVRAM. Do not recharge or burn this battery. Used NVRAM must be handled in accordance with local regulations.

SAFETY AND ECOLOGICAL NOTES FOR DISPOSAL 1. Do not incinerate toner bottles or used toner. Toner dust may ignite

suddenly when exposed to an open flame. 2. Dispose of used toner, developer, and organic photoconductors in

accordance with local regulations. (These are non-toxic supplies.) 3. Dispose of replaced parts in accordance with local regulations. 4. When keeping used lithium batteries in order to dispose of them later, do not

put more than 100 batteries per sealed box. Storing larger numbers or not sealing them apart may lead to chemical reactions and heat build-up.

LASER SAFETY The Center for Devices and Radiological Health (CDRH) prohibits the repair of laser-based optical units in the field. The optical housing unit can only be repaired in a factory or at a location with the requisite equipment. The laser subsystem is replaceable in the field by a qualified Customer Engineer. The laser chassis is not repairable in the field. Customer engineers are therefore directed to return all chassis and laser subsystems to the factory or service depot when replacement of the optical subsystem is required.

WARNING Use of controls, or adjustment, or performance of procedures other than those specified in this manual may result in hazardous radiation exposure.

WARNING WARNING: Turn off the main switch before attempting any of the procedures in the Laser Unit section. Laser beams can seriously damage your eyes. CAUTION MARKING:

LITHIUM BATTERIES CAUTION DANGER OF EXPLOSION IF BATTERY IS INCORRECTLY REPLACED. REPLACE ONLY WITH THE SAME OR EQUIVALENT TYPE RECOMMENDED BY THE MANUFACTURER. DISPOSE OF USED BATTERIES ACCORDING TO THE MANUFACTURER’S INSTRUCTIONS. VORSICHT

1.6 PRINTING PROCESS Overview

1. DRUM CHARGE The charge roller gives a negative charge to the organic photoconductive (OPC) drum. The charge remains on the surface of the drum because the OPC layer has a high electrical resistance in the dark.

2. LASER EXPOSURE Processed data from the computer/network is retrieved from the memory and transferred to the drum by a laser beam, which forms an electrical latent image on the drum surface. The amount of charge remaining as a latent image on the drum depends on the laser beam intensity, which is controlled by the engine board.

3. DEVELOPMENT The magnetic developer brush on the development rollers comes in contact with the latent image on the drum surface. Toner particles are electrostatically attached to the areas of the drum surface where the laser reduced the negative charge on the drum.

4. ID SENSOR The laser forms a sensor pattern on the drum surface. The ID sensor measures the reflectivity of the pattern. The output signal is one of the factors used for toner supply control. Also, the ID sensor measures the reflectivity of the drum surface. The output signal is used for charge roller voltage control.

1-15

5. IMAGE TRANSFER Paper is fed to the area between the drum surface and the transfer roller at the proper time for aligning the print paper and the developed image on the drum surface. Then, the transfer roller applies a high positive charge to the reverse side of the paper. This positive charge pulls the toner particles from the drum surface onto the paper. At the same time, the paper is electrostatically attracted to the transfer roller.

6. PAPER SEPARATION Paper separates from the drum as a result of the electrostatic attraction between the paper and the transfer roller. The discharge plate helps separate the paper from the drum.

7. CLEANING The cleaning blade removes any toner remaining on the drum surface after the image transfers to the paper.

8. QUENCHING The light from the quenching lamp electrically neutralizes the charge on the drum surface.

1.8.1 SWITCHES

The 8 switches (Go, Job Cancel, Secure Print, Reprint, +, -, Set, Back) enables to control the basic printer operations and change various printer settings. Key Function

Go Exit from the control panel menu. Reprint settings and clear error messages. Pause / Continue printing.

Job Cancel Stop and cancel the printer operation in progress. Secure Print Print secure documents. Reprint Select the Reprint menu. Menu + Move forwards through Menus and selectable options. - Move backwards through Menus and selectable options.

Set Select the Control menu. Set the selected menus and the numbers.

Back Go back one level in the menu structure.

1. Go Switch Pressing the Go switch once enables to change from the current status (MENU, ERROR and REPRINT settings). For ERROR indications, the panel will change only when it is possible to clear the error. The Go switch enables to PAUSE printing during a print job. Pressing the Go switch again makes the print job restart and clears the PAUSE. During PAUSE, the printer is in the off-line state.

NOTE: When the printer is in PAUSE and there is no need for printing the remaining data, the job can be canceled by pressing the Job Cancel switch before pressing the Go switch to clear the PAUSE.

2. Job Cancel Switch The Job Cancel switch enables to cancel the processing or printing of data. When the printer is in any other state except receiving or printing the data, the display shows “NO DATA!!!” and you cannot cancel the job.

2. DETAILED SECTION DESCRIPTIONS 2.1 LASER EXPOSURE 2.1.1 OVERVIEW

The LD unit [A] outputs a laser beam to the polygon mirror [B] through the cylindrical lens [C]. The shield glass [D] prevents dust from reaching the polygon mirror. Each surface of the polygon mirror reflects one full main scan line. The laser beam goes to the F-theta mirror [E], mirror [F], and BTL (barrel toroidal lens) [G]. Then the laser beam goes to the drum through the toner shield glass [H]. The laser synchronizing detector [I] determines the starting position for the main scan. The speed of the polygon mirror motor is 38,000 rpm for 600 dpi.

2.1.2 AUTO POWER CONTROL (APC)

The LD driver IC drives the laser diode. To prevent the intensity of the laser beam from changing because of the temperature, the machine monitors the current passing through the laser diode (LD). The machine adjusts the current to the laser diode by comparing it with the reference level from the reference circuit. This auto power control is done just after the machine is turned on and during printing while the laser diode is active. The laser diode power is adjusted on the production line. NOTE: Do not touch the variable resistors on the LD unit in the field.

2.1.3 LD SAFETY SWITCH

To ensure technician and user safety and to prevent the laser beam from inadvertently switching on during servicing, safety switches are located at the front cover and right cover. The switches are installed on the +5VLD line coming from the power supply unit through the Engine control board. When the front cover or the right cover is opened, the power supply to the laser diode is interrupted.

2.2.2 DRIVE MECHANISM

The main motor [A] drives the drum [B] through a series of gears, a timing belt [C], and the drum drive shaft [D]. The main motor assembly includes a drive controller, which outputs a motor lock signal when the rotation speed is out of the specified range. The fly-wheel [E] on the end of the drum drive shaft stabilizes the rotation speed (this prevents banding and jitter from appearing on printouts).

2.3 DRUM CHARGE 2.3.1 OVERVIEW

This machine uses a drum charge roller to charge the drum. The drum charge roller [A] is always in contact with the surface of the drum [B] to give it a negative charge of -900V. The high voltage supply board gives a negative dc voltage to the drum charge roller through the spring [C] and terminal plate [D].

2.3.2 CHARGE ROLLER VOLTAGE CORRECTION

Correction for Environmental Conditions

With a drum charge roller system, the voltage transferred from roller to drum varies with the temperature and humidity around the drum charge roller. The lower the temperature or humidity is, the higher the applied voltage required. To compensate, the machine uses the ID sensor to measure the effects of current environmental conditions. For this measurement, the process control parameters are balanced so that any small change in drum potential caused by environmental effects is reflected in a change in the amount of toner transferred to the drum. This measurement is made immediately after the ID sensor pattern for toner density control. Immediately after making the ID sensor pattern [A], the charge roller voltage stays on, but the development bias goes up to –600. As a result, the drum potential is reduced to -700V. The laser diode is not switched on, and the drum potential is now slightly higher than the development bias, so only a very small amount of toner transfers to the drum. The ID sensor measures the density of this pattern [B], and the output voltage is known as Vsdp. This voltage is compared with Vsg (read from the bare drum at the same time).

If the humidity drops, the drum potential goes up (to a higher –ve voltage) even if the charge roller voltage supply stays the same (efficiency of voltage transfer is higher with lower humidity). As a result, less toner is transferred to ID sensor pattern [B]. If the sensor output reaches a certain point, the drum charge voltage will be reduced. To determine whether to change the drum charge roller voltage, the machine compares Vsdp with Vsg. • Vsdp / Vsg > 0.95 = Reduce the magnitude of the drum charge voltage by 50 V • Vsdp / Vsg < 0.90 = Increase the magnitude of the drum charge voltage by 50 V 2.3.3 ID SENSOR PATTERN PRODUCTION TIMING

An ID sensor pattern is made in the following conditions. • During warming up at power on • If the machine starts warming up after entering the energy saver mode

2.3.4 DRUM CHARGE ROLLER CLEANING

Because the drum charge roller [A] is always in contact with the drum, it gets dirty easily. So, the cleaning pad [B] is also in contact with the drum charge roller all the time to clean the surface of the drum charge roller. The pin [C] at the rear of the cleaning pad holder touches the cam gear [D], and this gear moves the cleaning pad from side to side. This movement improves the cleaning.

2.4.2 DRIVE MECHANISM

The main motor [A] drives the development roller [B] and mixing augers [C] through a train of gears and the development drive shaft [D]. When the PCU is pushed in, the development drive shaft engages the development roller gear. The development drive gears (except for the gears in the development unit) are helical gears. These gears are quieter than normal gears.

2.4.3 DEVELOPER MIXING

This machine uses 2 mixing augers, [A] and [B], to keep the developer evenly mixed. Mixing auger 2 [A] transports excess developer, scraped off the development roller [C] by the doctor blade [D], towards the front of the machine. Mixing auger 1 [B] returns the excess developer, along with new toner, to the rear of the mixing assembly. Here the developer is reapplied to the development roller.

2.4.4 DEVELOPMENT BIAS

This machine uses a negative-positive development system, in which black areasof the latent image are at a low negative charge (about -150 ± 50 V) and whiteareas are at a high negative charge (about -900 V).

To attract negatively charged toner to the black areas of the latent image on thedrum, the high voltage supply board applies a bias of -600 volts to the developmentrollers throughout the image development process. The bias is applied to thedevelopment roller shaft [A] through the drive shaft [B].

The development bias voltage (-600 V) can be adjusted with the printer servicemode (ENGINE MENU: Developer bias).

2.4.5 TONER SUPPLY

Toner bottle replenishment mechanism

When a toner bottle is placed in the bottle holder unit [A] and the unit is pushed in completely, pin [B] moves against the side [C] of the PCU, and the toner shutter [D] is pulled out to open the bottle. When the toner bottle holder lever [E] is put back in the original position, the cap [F] on the toner bottle is pulled away and kept in place by the chuck [G]. The toner supply mechanism transports toner from the bottle to the development unit. The toner bottle has a spiral groove [H] that helps move toner to the development unit. When the bottle holder unit is pulled out to add a new toner bottle, the following happens automatically to prevent toner from scattering. • The chuck releases the toner bottle cap into its proper position. • The toner shutter shuts to block the opening as a result of pressure from a spring.

Toner supply mechanism

The toner supply motor [A] drives the toner bottle [B] and the mylar blades [C]. First, the toner falls down into the toner bottle holder. The toner supply mylar blades transfer the toner to the slit [D]. When the PCU is installed in the machine, the machine frame opens the shutter [E] above the PCU. Then the toner falls down into the development unit through the slit and the shutter.

There are four toner density control modes:

Mode P+T Control (Normally use this setting only) Toner supply decision Compare Vt with a reference voltage (Vts or Vref) Toner control process Toner is supplied to the development unit when Vt is higher

than the reference voltage (Vts or Vref). This mode keeps the Vref value for use the next toner density control. Vts is used for the first toner density control after a new PCU has been installed, until it has been corrected with the ID sensor output. Vref is used after Vts has been corrected with the ID sensor output voltage (corrected during the first toner density control for a new PCU).

Toner supply amount Varies Toner end detection Performed

Mode Fixed Quantity 1 (Designer’s use only; do not use in the field)

Toner supply decision Compare Vt with a reference voltage (Vts) Toner control process This toner control process is the same as the P+T control

mode. However, the reference voltage used is always Vts. Toner supply amount Varies Toner end detection Performed

Mode Fixed Quantity 2 (Designer’s use only; do not use in the field)

Toner supply decision Compare Vt with a reference voltage (Vts or Vref) Toner control process This toner control process is the same as the P+T control

mode. Toner supply amount Fixed Toner end detection Performed

Mode T Control (Use temporary if the TD sensor needs to be replaced)

Toner supply decision None Toner control process Toner is supplied every printed page regardless of Vt. Toner supply amount Fixed Toner end detection Not performed


2-19

Toner density sensor initial setting The TD sensor initial setting procedure is performed automatically when the new PCU is installed in the machine. During TD sensor initial setting, the TD sensor is set to the TD sensor output to the value programmed in the printer service mode (T sensor set: default: 2.3V). This value will be used as the standard reference voltage (Vts) of the TD sensor. Toner density measurement Toner density in the developer is detected once every print cycle. The sensor output voltage (Vt) during the detection cycle is compare with the standard reference voltage (Vts) or the toner reference voltage (Vref). Vsp/Vsg detection The ID sensor detects the following voltages.

• Vsg: The ID sensor output when checking the drum surface • Vsp: The ID sensor output when checking the ID sensor pattern

In this way, the reflectivity of both the drum surface and the pattern on the drum are checked. This compensates for any variations in the reflectivity of the pattern on the drum or the reflectivity of the drum surface. The ID sensor pattern is made on the drum by charge roller and laser diode. Vsg/Vsp is not detected every page or job; it is detected at the following times to decide Vref.

• During warming up at power on • If the machine starts warming up after a certain time has passed since

entering the energy saver mode. Toner supply reference voltage (Vref) determination The toner supply reference voltage (Vref) is the threshold voltage for the toner supply determination. Vref is determined using the following data,

• ID sensor output (Vsp/Vsg) • (Vts or the current Vref) - Vt

Toner supply determination The reference voltage (Vts or Vref) is the threshold voltage for determining whether or not to supply toner. If Vt becomes greater than the reference voltage, the machine supplies additional toner.


2-20

Toner Supply Motor On Time Determinations For sensor control modes 1 and 2, the toner supply motor on time is decided by the following factors.

• Vt • Vref or Vts • TD sensor sensitivity (coefficient: S, value is 0.4)

There are seven levels for toner supply motor on time as shown below.

Level Decision Motor On Time (seconds) 1 (Vts or Vref) < Vt ≤ (Vts or Vref) + S/16 t (0.6) 2 (Vts or Vref) < Vt ≤ (Vts or Vref) + S/8 t x 2 (1.2) 3 (Vts or Vref) < Vt ≤ (Vts or Vref) + S/4 t x 4 (2.4) 4 (Vts or Vref) < Vt ≤ (Vts or Vref) + S/2 t x 8 (4.8) 5 (Vts or Vref) < Vt ≤ (Vts or Vref) + 4S/5 t x 16 (9.6) 6 Vt ≥ (Vts or Vref) + 4S/16 (near-end) T (30); see note 7 Vt ≥ (Vts or Vref) + S (toner end) T (30); see note

NOTE: (30) means that toner is supplied intermittently in a 1/3 duty cycle (1 s on, 2

s off) for 30 seconds


2-21

2.4.7 TONER NEAR END/END DETECTION AND RECOVERY

The toner near end and end conditions are detected using the Vt and Vref values, in a similar way to toner density control. This is done in all toner supply modes except for fixed quantity 2, when toner end is not detected. Toner Near End Detection If Vt is at level 6 (see the table on the previous page) five times consecutively, the machine enters the toner near end condition and the toner end indicator starts blinking. Then the machine supplies toner for a certain time in accordance with the table explained in the previous section. Toner Near End Recovery If the machine detects “Vt < (Vref or Vts) + 4S/5” twice consecutively when in one of the following situations, the machine leaves the toner near end condition.

• While in the toner recovery cycle (supplying toner on and off for 30 s - see the previous page) after the machine has detected a toner near end condition.

• During printing in the toner near end condition. • If the front cover is opened and closed for more than 10 seconds while a

toner near end condition exists. Toner End Detection There are two situations for entering the toner end condition.

• When Vt is level 7 three times consecutively, the machine enters the toner end condition.

• When “Vt+S > Vt > (Vref or Vts) + 4S/5” is detected in the toner near end condition, then 50 prints can be made after this condition.

Toner End Recovery If the front cover is opened and closed for 10 seconds while a toner end condition exists and the toner bottle is replaced, the machine attempts to recover using the same procedure as for toner near end/end detection.

2.5 DRUM CLEANING AND TONER RECYCLING 2.5.1 DRUM CLEANING

The cleaning blade [A] removes any toner remaining on the drum after the image is transferred to the paper. This model uses a counter blade system. The cleaning blade scrapes off toner remaining on the drum. When toner builds up in the cleaning unit, toner at the top of the pile is removed by the toner collection coil [B]. To remove the toner and other particles that are accumulated at the edge of the cleaning blade, the drum turns in reverse for about 5 mm at the end of every print job.

2.5.2 TONER RECYCLING

Toner picked up by the toner collection coil [A], is transported to the opening [B] at the side of the PCU. Then, this toner falls into the development unit with new toner coming from the toner bottle and it is all mixed together by mixing auger 1 [C] and used again.

2.6.4 PAPER LIFT MECHANISM

The paper size switch detects when the tray is pushed in. When the paper tray is pushed into the machine, the pin [A] for the lift motor pressure shaft engages the lift motor coupling [B] and the pin [C] for the bottom plate lift shaft in the tray engages the bottom plate pressure lever coupling [D]. The pin [E] on the rear of the tray pushes the lock lever so that the lift motor can lift the bottom plate pressure lever. The lift motor turns on, and turns clockwise as viewed on the diagram. The main pressure spring [K] pulls the bottom plate pressure lever, and this lifts the tray bottom plate. When the top of the stack touches the feed roller, the motor cannot pull up the plate any more, so it pulls the actuator [G] into the lift sensor [F]. Then the lift motor reverses a certain time (200 ms or 600 ms), depending on the paper size, to reduce this pressure. For smaller paper, it reverses the larger amount (600 ms) to reduce the pressure more.

For A4-width paper or wider, a projection [H] on the side fence engages the secondary pressure spring [J] through a lever [I]. Then, the secondary pressure spring [J] applies paper feed pressure in addition to the main pressure spring [K], to ensure that extra pressure is applied to wider paper. When the paper tray is pulled out, the pins [A, C] disengage from the couplings [B, D], and the bottom plate drops. To make it easier to push the tray in, the lift motor rotates backwards 1.7 seconds to return the bottom plate pressure lever coupling [D] to the original position. 2.6.5 PAPER END DETECTION

If there is some paper in the paper tray, the paper stack raises the paper end feeler [A] and the paper end sensor [B] is deactivated. When the paper tray runs out of paper, the paper end feeler drops into the cutout [C] in the tray bottom plate and the paper end sensor is activated. When the paper tray is drawn out with no paper in the tray, the shape of the paper end feeler causes it to lift up.

G062D520.WMF

2-29

2.6.6 PAPER HEIGHT DETECTION

The amount of paper in the tray is detected by the combination of on/off signals from two paper height sensors [A] and [B]. When the amount of paper decreases, the bottom plate pressure lever [C] moves the actuator up. The following combination of sensor signals is sent.

Amount of Paper Paper Height Sensor 1 Paper Height Sensor 2 Near End OFF ON

30% ON ON 70% ON OFF 100% OFF OFF

When the tray contains paper of a small width, the paper feed pressure may become too low when the thickness of the remaining stack of paper has decreased. The lift motor rotates forward 400 ms after the sensor detects a certain amount of paper remaining in the tray to increase paper feed pressure, simulating the pressure generated by a full tray.

2.6.7 PAPER SIZE DETECTION

There are four paper size microswitches [A] on the front right plate of the paper tray unit. The switches are actuated by a paper size actuator [B] behind the paper size indicator plate, which is on the front right of the tray. Each paper size has its own actuator, with a unique combination of notches. To determine which size has been installed, the CPU reads which microswitches the actuator has switched off. The CPU disables paper feed from a tray if the paper size cannot be detected. If the paper size actuator is broken, or if there is no tray installed, the Add Paper indicator will light. When the paper size actuator is at the “*” mark, the paper tray can be set up to accommodate one of a wider range of paper sizes by using user tools. If the paper size for this position is changed without changing the user tool setting, a paper jam will result.

2.6.8 SPECIAL PAPER SETTING

When feeding thick paper and envelopes, the user must use the 2nd paper tray (if the optional multi-purpose tray is not installed), and turn lever [A] to the right. Then, when sliding the tray into the machine, the lever does not push the special paper switch [B] (it stays off), and the machine detects that there is special paper in the 2nd paper tray. When the machine detects the special paper signal, the fusing temperature and the transfer roller current will be changed as follows.

1. Fusing temperature: Current operation temperature +10 °C 2. Transfer roller current:

A3 width (11"): 14 µA

B4 width (10"): 15 µA

A4 width (8.5"): 17 µA

A5 width (5.5"): 20 µA Note that for the by-pass tray, the fusing and transfer conditions for special paper are also applied if the user uses thick (non-standard) mode.

2.6.9 SIDE AND END FENCES

Side Fences If the tray is full of paper and it is pushed in strongly, the fences may deform or bend. This may cause the paper to skew or the side-to-side registration to be incorrect. To correct this, each side fence has a stopper [A] attached to it. Each side fence can be secured with a screw [B], for customers who do not want to change the paper size. End Fence As the amount of paper in the tray decreases, the bottom plate [C] lifts up gradually. The end fence [D] is connected to the bottom plate. When the tray bottom plate rises, the end fence moves forward and pushes the back of the paper stack to keep it squared up.

2.7.2 IMAGE TRANSFER MECHANISM

There are two transfer current levels: low transfer current level and high transfer current level. The image transfer procedure is as follows:

1. When the CPU receives the image writing start signal, the CPU instructs the high voltage supply board to supply +10µA (low transfer current level) to the roller. This prevents any positively charged toner on the drum surface from transferring to the transfer roller.

2. At a certain time after the low transfer current has been supplied to the roller, +13µA (paper fed from the paper tray) is applied to the roller to transfer the toner to the paper.

3. After the trailing edge of the paper has passed through the roller, transfer current turns off. In multiple printing, the transfer current shifts again to the low transfer current.

The default transfer roller current (high transfer current level) is as shown in the following table. The transfer current can be adjusted using the printer service mode, except for the low transfer current.

Paper Size Paper Tray Duplex Multi-purpose Tray /

2nd Paper Tray (Special Paper)

A3/11" x 17", A4/81/2 x 11" SEF 13 µA 10 µA 14 µA

B4 13 µA 12 µA 15 µA A4/11" x 81/2 LEF, A5/51/2 x 81/2 SEF 13 µA 16 µA 17 µA

A5/81/2 x 51/2 LEF 15 µA 16 µA 20 µA

Be careful when increasing the transfer current. This might cause a ghosting effect, in which part of the image at the top of the page is repeated lower down the page at a lower density. It may also damage the OPC drum in the worst case.

2.8.2 FUSING DRIVE AND RELEASE MECHANISM

The main motor [A] drives the fusing unit through a gear train and drives the paper exit rollers [B] through a timing belt [C]. The fusing unit release mechanism automatically disengages the fusing unit drive gear [D] when the right cover [E] is opened. This allows the fusing unit drive gear to rotate freely so that misfed paper can easily be removed.

2.8.3 FUSING ENTRANCE GUIDE SHIFT MECHANISM

The entrance guide [A] is adjustable for paper thickness to prevent creasing. The left screw holes [B] on each side are used as the default setting. If creasing occurs frequently in the fusing unit, adjust the entrance guide to the right, by securing it with the other holes [C]. This allows more direct access to the gap between the hot roller and the pressure roller.

2.8.4 PRESSURE ROLLER

The pressure springs [A] constantly apply pressure between the hot roller [B] and the pressure roller [C]. Applied pressure can be changed by adjusting the position of the pressure springs. The spring is positioned at the top [D] as the default setting. The user moves the lever [E] when using thicker copy paper or envelopes, to reduce the pressure between the hot and pressure rollers. 2.8.5 CLEANING MECHANISM

The cleaning roller [A] is always in contact with the pressure roller [B]. It collects toner and paper dust adhered to the surface of the pressure roller.

2.8.7 FUSING TEMPERATURE CONTROL

Temperature Control When the main power switch is turned on, the CPU turns on the fusing lamp to maintain the fusing temperature of 180°C for the first job, or for the first 11 consecutive pages of printing. After that, the machine maintains the fusing temperature at 170°C. To prevent each end of the hot roller temperature from becoming too high, the machine lowers the fusing temperature to 155°C when it detects that paper which is less than 216 mm width is consecutively fed.

2.8.8 OVERHEAT PROTECTION

If the hot roller temperature becomes higher than 231°C, the CPU cuts off the power to the fusing lamp. At the same time, SC543 is generated. Even if the thermistor overheat protection fails, there is a thermalfuse in series with the common ground line of the fusing lamp. If the temperature of the thermalfuse reaches 169°C, the thermalfuse opens, removing power from the fusing lamp. At the same time, SC 542 is generated and the machine stops operating. 2.8.9 PAPER EXIT

The paper overflow detection sensor [A] is located at the paper exit section of the fusing unit. When this sensor is activated, the machine detects that the paper stack exceeded the certain limit and stops printing.

consumption by lowering or switching off the fusing lamp.This machine has two types of energy saver mode.

• Energy saver mode: The machine turns off the fusing lamp.

Entering Energy Saver Mode

Energy saver mode starts after the machine has been idle for a certain time. Thisperiod is specified by the user.

• Energy saver mode: 1-240 min (default 240 min)

4.1.1 PCU

The PCU consists of the drum, development unit, charge roller unit, and cleaning unit. Follow the cautions below when handling a PCU.

1. Never touch the drum surface with bare hands. When the drum surface is touched or becomes dirty, wipe it with a dry cloth or clean it with wet cotton.

Wipe with a dry cloth after cleaning with the cotton.

2. Never use alcohol to clean the drum; alcohol dissolves the drum surface.

3. Store the PCU in a cool dry place away from heat.

4. Never expose the drum to corrosive gases such as ammonia gas.

5. Never shake the used PCU. Doing so may cause toner and/or developer to be

spilt out.

6. Dispose of used PCU in accordance with local regulations.

4.1.2 TRANSFER ROLLER UNIT

1. Never touch the transfer roller surface with bare hands.

2. Take care not to scratch the transfer roller as the surface is easily damaged.

4.1.3 LASER UNIT

1. Do not loosen the screws that secure the LD drive board to the laser diode casing. Doing so would throw the LD unit out of adjustment.

2. Do not adjust the variable resistors on the LD unit, as they are adjusted in the factory.

3. The polygon mirror and F-theta mirror are very sensitive to dust. Never open

the optical housing unit.

4. Do not touch the glass surface of the polygon mirror motor unit with bare hands.

4.1.4 FUSING UNIT

1. After installing the fusing thermistor, make sure that they contact the hot roller

and that the roller rotates freely.

2. Be careful not to damage the edges of the hot roller strippers or their tension

springs.

3. Do not touch the fusing lamp and rollers with bare hands.

4. Make sure that the fusing lamp is positioned correctly on both lamp holders and

that it does not touch the inner surface of the hot roller.

4.1.5 PAPER FEED

1. Do not touch the surfaces of the pick-up, feed, and separation rollers.

2. The side fences and end fences of the paper tray must be positioned correctly to align with the paper to avoid paper misfeeds.

4.1.6 OTHERS

1. The TD sensor initial setting is performed automatically after installing a new PCU and closing the front cover. Never open the front cover or turn off the main

switch during this time. The main motor stops when the initial setting has finished.

2. The main switch must be kept on while the toner bottle is replaced.

2.2 DETAILED SECTION DESCRIPTIONS 2.2.1 SHIFT TRAY MECHANISM

Stack height detection

The stack height detection lever [A] is driven by the detection lever solenoid [B]. The stack height of the shift tray is detected by the status of two sensors, the stack height [C] and lever [D] sensors.

Stack height sensor Lever sensor Status

Off Off The stack height is below the target. The shift tray is lifted to the target position.

Off On Target position

On On The stack height is over the target. The shift tray is lowered to the target position.

On Off The stack height detection lever is at the home position.

At the start of a print job, the stack height detection lever comes out to detect the current stack. The lever is held inside the unit just before the paper exits by activating the solenoid. It comes out again just after the paper exits by deactivating this solenoid.

Shift tray up/down mechanism

When the stack height is out of the target position, the tray is raised or lowered by the shift tray motor [A]. Two gears [B] keep the angle of the tray constant at any tray position. When the stack near-full sensor [C] is on, a stack near-full signal is transferred to HL-3260N. When the upper limit sensor [D] is on, a finisher error signal is transferred to HL-3260N and a finisher error is indicated on the LCD panel.

2.2.2 PAPER FEED

Overview The following paper feed out modes can be selected in the printer driver.

Mode Description Straight feed out mode Paper is fed out directly to the shift tray without shifting and/or

stapling. Shifting mode Sets of papers are shifted then fed to the shift tray. Staple mode Sets of papers are shifted, stapled and then fed to the shift tray.

Straight feed out mode

When HL-3260N starts printing, the stack height detection lever moves to detect the current stack height and adjusts the position of the tray if the stack height is not in the target position.

When the paper exit sensor of HL-3260N turns on, the main motor for the finisher starts rotating, driving the paper exit unit gear [A] through idle gear [B]. The paper exit unit [C] is pushed down by the paper exit link [D], which is driven by the paper exit unit gear. When there is no exit unit gear thread facing the idle gear, gear rotation stops. This position is maintained by the solenoid lever [E]. The movements of exit roller drive gear [F] and paper exit guide [G] are linked with the movement of the paper exit link. When the paper exit unit is lowered, the exit roller drive gear comes in contact with the paper exit roller [H] and the paper exit guide is lowered to bring the paper in contact with the paper exit roller.

After paper exiting is complete, the stack height is detected again and the tray is adjusted to the target zone. Stack height detection is done page-by-page. When the last page is fed out, the paper exit unit solenoid turns on to restart the unit gear rotation. This rotation causes the paper exit unit to rise. Then, the main motor stops rotating the unit gear and the solenoid turns off. Shifting mode

The paper drops into the jogger tray [B]. The paddle roller solenoid [C] turns on and rotates the paddle roller [D] on. The paddle roller feeds the paper to the caterpillar roller [E]. The caterpillar roller feeds the paper to the end fence [F] of the jogger tray.

The jogger fence [A] shifts the paper sideways to the end fence of the jogger tray [B]. The jogger motor [C] drives the jogger fence, returning it to its home position. The home position sensor [D] detects when the jogger fence has returned to the home position after shifting. All pages of a set are fed out together with the first page of the next set fed out in straight feed out mode. If shifting mode is applied to the last set, the paper exit unit is pushed down and the last set is fed out.

Staple mode

After shifting all pages of a set, the paper exit link lever [A] pushes the paper exit unit [B] down until the knob of the exit unit [C] pushes the link lever [D] for the exit unit switch [E]. This turns on the exit unit switch. While turning on this switch, a DC current is supplied to the stapler unit [F] and the main motor is turned off. After stapling the set, the paper exit unit is pushed down again until the unit comes into contact with the paper exit roller [G] and the set of stapled paper is fed out.

2. DETAILED DESCRIPTIONS 2.1 BASIC OPERATION

The mailbox is connected to the main unit by a 10-pin connector. When the leading edge of the paper activates the exit sensor on the interchange unit, the mailbox main motor turns on and the mailbox rollers begin to turn. The paper is then fed out to the tray that has been selected. Solenoids [B] open and close junction gates as shown to direct the paper to the selected tray. When the top tray (tray 4) is selected, none of the solenoids are activated. As the last sheet is fed out, it turns off the vertical transport sensor, and both the mailbox motor and the junction gate solenoid of the selected bin turn off. The mailbox normally feeds paper at 121 mm/s. For HL-3260N, this is about equal to the speed of the printer itself (actual transport speeds are: 121.6 mm/s and 120.6 mm/s, respectively).

2.2 PAPER OVERFLOW DETECTION 2.2.1 OVERVIEW

Overflow sensors are installed in each tray. They monitor the trays so that the amount of paper present does not exceed the tray capacity. If a printing job is done that exceeds the capacity of one or more of the trays, HL-3260N recognizes the overload, displays an error message and stops the print job. However, if the excess paper is removed from the overloaded tray, the print job will continue. 2.2.2 DETECTION TIMING

When the sensor output is high for longer than T (calculated by the equation below), the machine determines that the tray is full. The detection timing for a full tray is calculated by the equation below for each paper size. For example, with a minimum print speed of 12 ppm (for A3), the value of T would be 15 seconds. Therefore, if the sensor continuously detects paper for 15 or more seconds (as it would if the tray were actually full and a given sheet of paper was stopped at the sensor), HL-3260N stops the copy job, assuming that the tray is full. The value of T will be different for each paper size, since the print speed will vary with paper size. T (seconds) = (60/min. PPM) x 3 * PPM = prints per minute.

interchange unit, a misfeed is detected if this sensor does not turn off within X + 0.52 s, where X is equal to the amount of time a given paper size takes to pass the sensor (e.g. A4 – sideways = 1.74 s).

J2 Timing: After the paper exit sensor of the interchange unit is activated, the machine determines that the paper has not yet fed and detects a misfeed if the vertical transport sensor does not activate within 1.94 s (in the case of A4 paper).

J3 Timing: After the vertical transport sensor is activated, a misfeed is detected if this sensor does not turn off within X + 0.52 s (see above for an explanation of X). For example, this value would be 2.26 s for A4 sideways.

2.2 FEED IN AND EXIT MECHANISM

When paper is fed into duplex unit: As soon as the paper is fed from the interchange unit, it is sent to the inverter section [C] (the inverter gate solenoid [A] remains off during this process). The inverter section can hold a sheet of paper up to A3 size or two sheets of paper A4 size or less. Inversion and Exit: Shortly after the trailing edge of the paper passes the entrance sensor [G], the inverter gate solenoid [A] switches on and the inverter gate [B] switches over to direct the paper to the exit path [E]. The inverter roller [D] then changes its rotation direction and the paper goes to the exit transport area [F]. The paper is then sent to the registration rollers in HL-3260N by the transport rollers.

2 DETAILED DESCRIPTIONS 2.1 BASIC OPERATION

The multi-purpose tray unit uses a friction pad paper feed mechanism. The transport roller gear in the main printer drives the gear on the paper feed clutch [B] through a series of gears. When paper is placed in the tray, the paper end sensor [C] switches off. When the Start button is pressed, the paper feed clutch [B] is activated and the paper feed roller [A] feeds the paper one sheet at a time.

MP5000-4

2.2 PAPER SIZE DETECTION

The paper size sensor board [B] monitors the paper width. The rear side fence [A] is connected to the terminal plate. The pattern for each paper width is unique. Therefore, the HL-3260N determines which paper has been placed in the multi-purpose tray by the signal output from the board. However, the HL-3260N will not determine the paper length from the multi-purpose tray hardware (refer to Original Size Detection in the HL-3260N manual for details on how paper length is determined).

2. DETAILED SECTION DESCRIPTIONS 2.1 PAPER FEED

This products uses an Feeder Reverse Roller type paper feed mechanism. The paper feed unit consists of the pickup roller [A], paper feed roller [B], reverse roller [C], and grip and transport rollers. There is a torque limiter in the back of the reverse roller (ferrite powder type).

2.2 REVERSE ROLLER AND PICK-UP ROLLER RELEASE

To prevent the paper from being torn when pulling out the paper feed tray, the reverse and pickup rollers are constructed so that they release automatically. When the paper tray [A] is not inside the machine, the reverse roller [B] is away from the paper feed roller [C] and the pick-up roller [D] stays in the upper position. When the paper tray is set into the machine, it pushes the release lever [E]. This causes the pick-up roller [D] to go down into contact with the top sheet of paper and the reverse roller [B] to move up and contact the paper feed roller.

2.3 TRAY LIFT

When the paper feed tray is put in the machine, the tray switch [A] on the back face turns on and the tray lift motor [B] starts up. The base plate lift shaft [C] is coupled to the lift motor by shaft [D], so the base plate of the tray is lifted. After a short while, the top of the paper stack contacts the pick-up roller and lifts it up. When this occurs, the actuator enters the upper limit sensor, the sensor turns off and the lift motor stops. When paper in the tray is used up, the pick-up roller is gradually lowered, and the actuator leaves the upper limit sensor (turning the sensor on). When this happens, the lift motor begins turning again. The tray will then be lifted until the actuator enters the upper limit sensor (turning the sensor off again). When the tray is removed from the copier, the coupling between the lift motor [B] and base plate lift shaft [C] is broken and the base plate goes into a controlled free fall (using a damper [E] to slow the fall and prevent damage).

2.4 NEAR END/END DETECTION This tray can hold two stacks of paper, so the machine needs to monitor the status of both these stacks. There are seven sensors to do this. In the right tray (paper feed side), three height sensors measure the height of the stack, and an end sensor detects when all the paper is used up. As the amount of paper remaining in the tray decreases, the base plate rises and the actuator activates the paper height sensors. When the paper runs out in the right tray, the stack in the left tray is moved across to the right tray. There are also two height sensors ([F] in the diagram on the previous page) and an end sensor in the left tray (paper storage side) ([G] in the diagram on the previous page). When there is no paper in both trays, paper end is detected. The machine determines the amount of remaining paper based on the sensor outputs. The following table shows all possible paper fill conditions in the tray. Sensors: ! = paper present # = no paper

2.5 RIGHT TRAY SIDE FENCE

When the paper in the right tray is used up, the side fence solenoid [F] activates and stays on until the side fence open/closed sensor [E] detects that the fence is open. The rear fence [A] then moves the stack of paper from the left tray into the right tray, as described in the following section. When the stack has been transferred to the right tray, the rear fence return sensor [G] detects the rear fence and then turns off the side fence open solenoid (closing the side fence). The side fence open/closed sensor [D] detects when the side fence is closed. When it is not closed, the user is prompted by a message on the HL-3260N LCD display to free the mechanism. 2.6 LEFT TRAY REAR FENCE If the right tray paper end sensor detects that there is no paper in the tray (while the left tray sensor detects that there is still paper in the left tray), the right side fence [C] opens and the rear fence motor [H] turns on. The rear fence of the left tray moves and the paper stack is then transferred from the left tray to the right tray. When the left tray rear fence activates the rear fence return sensor, the machine detects that the paper stack has been transferred to the right tray and the rear fence motor rotates in the opposite direction. When the rear fence HP sensor [B] comes on, the motor stops.

2.7 RIGHT TRAY PAPER END DETECTION

The paper end sensor [A] detects when paper in the right tray runs out. When there is paper in the tray, the paper pushes up the paper end feeler [B] and causes the actuator to come between the LED and photo diode of the sensor. When paper runs out, the feeler drops and the actuator leaves the photointerruptor, and the machine detects that there is no paper in the tray. When the tray is being pulled out, the lever [E] lifts the pick-up roller and this also lifts up the feeler arm.

2. DETAILED DESCRIPTIONS 2.1 PAPER FEED AND SEPARATION MECHANISM

The paper tray holds 500 sheets. The paper feed roller [A] drives the top sheet of paper from the paper tray to the HL-3260N. The friction pad [B] allows only one sheet to feed at a time. The friction pad applies pressure to the feed roller with a spring [C].

2.2 PAPER LIFT MECHANISM

The paper size switch detects when the tray is pushed in. When the paper tray is pushed into the machine, the pin [A] for the lift motor pressure shaft engages the lift motor coupling [B] and the pin [C] for the bottom plate lift shaft in the tray engages the bottom plate pressure lever coupling [D]. The pin [E] on the rear of the tray pushes the lock lever so that the lift motor can lift the bottom plate pressure lever. The lift motor turns on, and turns clockwise as viewed on the diagram. The main pressure spring [K] pulls the bottom plate pressure lever, this lifts the tray bottom plate. When the top of the stack touches the feed roller, the motor cannot pull up the plate any more, so it pulls the actuator [G] into the lift sensor [F]. The pressure of the feed roller on the paper is now too high, so the lift motor reverses to reduce this pressure. It reverses for 300 ms or 600 ms, depending on the paper size. For smaller paper, it reverses the larger amount (600 ms) to reduce the pressure more.

LT5100-8

For A4-width paper or wider, a projection [H] on the side fence engages the secondary pressure spring [J] through a lever [I]. Then, the secondary pressure spring [J] applies paper feed pressure in addition to the main pressure spring [K], to ensure that extra pressure is applied to wider paper.

When the paper tray is pulled out, the pins [A, C] disengage from the couplings [B, D], and the bottom plate drops. To make it easier to push the tray in, the lift motor rotates backwards for 1.7 seconds to return the bottom plate pressure lever coupling [D] to the original position. 2.3 PAPER END DETECTION

If there is some paper in the paper tray, the paper stack raises the paper end feeler [A] and the paper end sensor [B] is deactivated. When the paper tray runs out of paper, the paper end feeler drops into the cutout [C] in the tray bottom plate and the paper end sensor is activated. When the paper tray is drawn out with no paper in the tray, the shape of the paper end feeler causes it to lift up.

2.4 PAPER HEIGHT DETECTION

The amount of paper in the tray is detected by the combination of on/off signals from two paper height sensors [A] and [B]. When the amount of paper decreases, the bottom plate pressure lever [C] moves the actuator up. The following combination of sensor signals is sent to HL-3260N.

Amount of Paper Paper Height Sensor 1 Paper Height Sensor 2 Near End OFF ON

30% ON ON 70% ON OFF 100% OFF OFF

When the tray contains paper of a small width, the paper feed pressure may become too low when the thickness of the remaining stack of paper has decreased. The lift motor rotates forward 300 ms after the sensor detects a certain amount of paper remaining in the tray to increase paper feed pressure, simulating the pressure generated by a full tray.

2.5 PAPER SIZE DETECTION

There are four paper size microswitches [A] on the front right plate of the paper tray unit. The switches are actuated by a paper size actuator [B] behind the paper size indicator plate, which is on the front right of the tray. Each paper size has its own actuator, with a unique combination of notches. To determine which size has been installed, HL-3260N reads which microswitches the actuator has switched off. HL-3260N disables paper feed from a tray if the paper size cannot be detected. If the paper size actuator is broken, or if there is no tray installed, the Add Paper indicator will light. When the paper size actuator is at the “*” mark, the paper tray can be set up to accommodate one of a wider range of paper sizes by using user tools. If the paper size for this position is changed without changing the user tool setting, a paper jam will result.

2.6 SIDE AND END FENCES

Side Fences If the tray is full of paper and it is pushed in strongly, the fences may deform or bend. This may cause the paper to skew or the side-to-side registration to be incorrect. To correct this, each side fence has a stopper [A] attached to it. Each side fence can be secured with a screw [B], for customers who do not want to change the paper size. End Fence As the amount of paper in the tray decreases, the bottom plate [C] lifts up gradually. The end fence [D] is connected to the bottom plate. When the tray bottom plate rises, the end fence moves forward and pushes the back of the paper stack to keep it square in the tray.
