THEORY OF OPERATION

Printer Paper Path

Internal Duplex: Models T652 & T654

NOTE: Duplex on the T652 or the T654 is not a field installable option. In order for a model T652 or a model T654 to have duplex capability, it must be ordered that way initially. On rare occasions you may encounter a simplex T652x or T654x that has had the duplex option disabled at the factory to satisfy a customer’s requirement. In this situation, the duplex hardware has not been removed. The disabling action is not reversible in the field.



Duplex: Models T650

Duplex is a field installable option for model T650 only. It is functionally the same theory of operation & uses the same basic paper path as did the T64x series printers.



Print Engine Transport System

Paper Tray Components New spring-loaded side guide that enhances feeding & imaging consistency.

• This left side guide helps prevent paper skewing. The spring loaded guide positions itself to the nearest setting, allowing for imprecise setting of guides.

• Doesn’t have to be reset with every ream. It allows a little forgiveness for

aggressive paper loading. T65x Paper drawer holds 550 instead of 500. This allows a customer to load a full ream of paper prior to totally emptying the drawer.

Multiple Sheet Feed Prevention Media occasionally sticks together along the edges when loaded in the Tray. This may cause a multiple sheet feed or paper jam. Wider restraint pads (on bottom of tray) help with bottom of tray multi-feeds.

Textured Ramps – use the same principals as our Special Media Tray, causing fewer multi-feeds.

The T65x paper trays have several enhanced features: The back guide is easier to move.

There is a rear guide locking system that ensures consistent sensing & behavior of the media. It won’t get knocked out of position. Ships locked according to geo.



Electrophotographic Process

Charge: The twin charge rollers deposit a uniform negative electrostatic charge on the light-sensitive surface of the photoconductor drum: (also called the PC, Photodeveloper, or OPC).

Exposure: The printhead generates Laser light that enters the cartridge and strikes the photoconductor (PC) drum in areas to be developed, forming an invisible (latent) electrostatic image of the desired print. Note: Any form of light (laser, LED's, sun light, etc.) activates the Electrophotographic (EP) properties of the drum coating. Consequently, care should be taken to cover the PC when removed from the printer to protect it from exposure to a light source.

Development: (Developer Roll) Toner is transferred from the reservoir in the toner cartridge to the photoconductor drum through electrostatic attraction making the image visible on the PC drum. Toner is attracted only to areas where the laser imaged the drum. Since the toner and the charge applied to the drum are both negative, the toner will be repelled from areas where the laser did not image the drum.

Transfer: The transfer roll rolls along the underside of the paper to be imaged, and moves the toned image from the photoconductor to the paper. The toner is negatively charged and the transfer roll bathes the paper with a positive charge; this attracts the toner to the paper.

Fusing: The paper – now with a “toned” image – moves through the fuser assembly. Using temperature and pressure, it marries toner to paper.

Cleaning: Waste toner (toner that was not transferred), paper debris and dust are removed from the photoconductor drum by the cleaning blade.

Printheads [Oscillating vs. Spinning Polygon Mirror] You need to be aware that there are differences in these two types of printheads. Both the alignment procedures for each type of printhead, as well as the basic diagnostic steps are different. This printhead has an alignment procedure that is shown in the next section.

T650 & T650n The T650 & T650n use an oscillating printhead and uses bidirectional printing. This printhead has a tuning step in addition to the alignment procedure during installation.

T652dn & T654dn The T652dn & T654dn use a spinning polygon mirror printhead, as did the T64x. This printhead is 40% larger than the oscillating printhead and uses unidirectional printing. This printhead has an alignment procedure that is shown in the next section.

Forward Reverse



Polygon & Oscillating printhead assembly adjustment Do the printhead mechanically registration adjustment whenever you remove or replace the printhead or loosen the mounting screws. Install the new printhead with the mounting screws centered in the slots in the printhead frame assembly. Leave the screws loose enough to allow the printhead to move from side to side within the slots. It is necessary to perform a mechanical registration adjustment before locking down the three printhead mounting screws.

In case of paper feed skew, go to “Alignment assembly – skew adjustment” [Page 15] To perform the mechanical registration adjustment of the printhead: 1. Turn the printer off.

2. Press and hold and to enter the diagnostic mode. 3. Turn the printer on, and release the buttons when Performing Self Test displays. 4. Select Registration from the menu. 5. Select Quick Test Page. The test page should only be printed on letter or A4 paper from Tray 1. The

Quick Test Page consists of alignment diamonds, horizontal lines that can be used for mechanical registration adjustment. An example of the printhead alignment printout is shown below:



6. Check the Quick Test Page for any sign of misalignment by checking the diamonds at the top left and top right of the test page for equal distance from the top of the page. If necessary, rotate the printhead to the left or right and tighten down the mounting screws and check for proper alignment again by running another Quick Test Page. This procedure may take two or three attempts before you get satisfactory results.

7. When you have the correct adjustment, ensure that the printhead mounting screws are properly tightened.



Oscillating printhead assembly electronic adjustment A step-by-step process to align a new printhead. Note: Before aligning the printhead electronically, first align the printhead mechanically, if needed. See “Oscillating printhead assembly adjustment” [on Page 12] 1. Turn the printer off.

2. Press and hold and to enter the diagnostic mode. 3. Turn the printer on, and release the buttons when Performing Self Test displays. 4. Select Registration from the menu. 5. Select Quick Test Page. The test page should only be printed on letter or A4 paper from Tray 1. The

Quick Test Page consists of alignment diamonds, horizontal lines that can be used for skew adjustment, page count setting, printer serial number code levels, and print registration settings. An example of the printhead alignment printout is shown below:

6. In the Registration menu, select the Right Margin setting. 7. To determine the margin setting, choose the value that is closest to the darkest bar on the center

graph on the margin page. Add that value to the current right margin setting printed on the left hand side of the margin page (The right margin setting will also appear on the operator panel display under right margin setting). For example, if the right margin setting on the sheet is -2, and the number that is closest to the darkest line on the graph is 3, the you would enter (-2+3=+1) The new right margin setting on the op. panel should now equal +1.

8. Press or to the desired setting, and press . 9. Print the Quick Test page again and check that the darkest line in the center graph is equal to zero. If

it is, then check to see if the left, top, and bottom margins are detected. If it is not, then repeat step 7. Note: The alignment of the left margin positions the black plane to the right or left. The alignment of the right margin does not alter the margins and should only be used to adjust the printhead.



Alignment assembly – skew adjustment Do the alignment assembly adjustment whenever you replace the alignment assembly. Always print a copy of the Quick Test Page before making any adjustments to the alignment assembly reference adjustment screw. When replacing the alignment assembly, it is necessary to back the reference adjustment screw out far enough to remove the old assembly and install the new one.

• If you are replacing the alignment assembly, go to step A. • If you are only adjusting the reference adjustment screw, go to step B.

Step A Print a copy of the Quick Test Page and check the margin adjustments printed on the test page. These settings should be within the range specified in “REGISTRATION” shown below: Variable Description Value Direction of change

T= Top margin -25 to +25 Each increment causes approximately 4 pels shift (at 600 dpi).

A positive change moves the image down the page and increases the top margin. A negative change moves the image up and decreasesthe top margin.

B= Bottom margin -20 to +20 Each increment causes approximately 0.55 mm shift in thebottom margin.

A positive change compresses the image so it appears to move down the page and a negative change moves the image up.

L= Left margin - -25 to +25 A positive change moves the image to the right, and a negative change moves the image to the left. No compression occurs.

M= Right margin - 99 to +99 A positive change moves the image to the right, and a negative change moves the image to the left.

Do the reference adjustment if you are sure the margins are set correctly. 1. Loosen the locknut on the inside rear of the alignment assembly. 2. Remove the two screws holding the alignment assembly to the left side frame. 3. Back the reference adjustment screw out far enough to allow the alignment assembly to be removed

from the printer. It is not necessary to completely remove the screw. 4. Install the new alignment assembly. Turn the reference screw clockwise with a 7 mm nut driver or M3

Allen wrench until it touches the back of the reference plate, and tighten the nut with a 5.5 mm wrench.



The reference adjustment screw can be adjusted without loosening the nut. Turn the screw clockwise a few turns and print a copy of the Quick Test Page as you check the diamonds on the left margin. Continue adjusting the screw as you check the results of each adjustment on a new test page until you obtain the results you want. Step B Print a copy of the Quick Test Page, and check the margin adjustments printed on the test page. These settings should be within the range specified in “REGISTRATION” shown in chart in section A above. The reference screw can be adjusted without loosening the locknut. Turn the screw a few turns, and print a copy of the Quick Test Page as you check the diamonds on the left margin. Continue adjusting the screw as you check the results of each adjustment on a new test page until you obtain the results you want.



Document Scanning

Document scanning at ADF The document scanning section of this machine consists of a scanner that reads a single-sheet document placed on the platen glass and a document feeder that can transport a multiple-sheet document for one or two sided scanning.

Document scanning at platen Shown below is the operational overview of document scanning at the platen. The scanner CCD assembly travels to read the document. The exposure lamp is installed on the scanner CCD assembly. As the scanner CCD assembly travels, the document on the platen glass is scanned and exposed with the exposure lamp. The image data is read with the scanner CCD image sensor assembly. This ADF employs a constant velocity transport system that scans images by feeding the document at a constant speed over the specified position (scan position) where the carriage of the scanner unit assembly is fixed.

Names and functions of components The sections below describe the functions of main components of the scanner.

Flatbed (FB) Scanner unit assembly – [APS; automatic paper sensor] Sensor (FB length APS 1), Sensor (FB length APS 2), Sensor (FB length APS 3)

The document length in the slow scanning direction is detected by a combination of the three reflector sensors.

Switch (ADF closed interlock) A switch that detects whether the ADF is open and determines the timing of platen document size detection.

Scanner drive motor assembly A stepping motor that drives the scanner CCD assembly.



Sensor (FB scanner HP [home position]) A sensor that detects the HP position of the flatbed scanner CCD assembly.

Scanner exposure lamp A xenon lamp to which the document is exposed.

Scanner controller card assembly A card that controls the scanner section.

Scanner cooling fan A fan that prevents overheating of the scanner controller card assembly and exposure lamp.

A document sheet set in the document tray assembly is fed through the ADF feed roll, ADF pick roll, and ADF separation roll assembly. The document image is scanned at the scan position, and the document sheet is ejected through the ADF feed-out roll assembly and the ADF exit roll assembly. For a duplex document sheet, the image on side 1 and the image on side 2 are scanned at the same time in the same pass. Described below is the overview of the steps before document scanning and that of simplex and duplex document scanning modes.

Setting a document

When a document is set on the document tray assembly and the lead edge is pushed into the tray until it stops, the ADF document set actuator moves to place the sensor (ADF document set) in the unshielded (unblocked) state. Then the machine recognizes that the document has been set properly, turning on the document set LED.

Preparation for feed

Pressing the start button with the document set in the document tray will start feeding the document. First the pick roll moves down and presses the document on the document tray to enable document feed. The pick roll moves down with the normal rotation of the ADF feed drive motor assembly and it moves up with the reverse rotation of the ADF feed drive motor assembly. Upon completion of document feed, the pick roll returns to the normal (raised) position.



Document feed path from the ADF Shown below is the document feed path from the ADF. Simplex and duplex document feed

For two simplex document sheets, feed is performed in the following sequence: 1. The first document sheet is fed to the ADF transport roll assembly. 2. The document is fed to the ADF registration roll assembly, and then fed to the scan feed reference position. 3. The document sheet is fed at the feed speed corresponding to the selected magnification, and the image on it is scanned with the exposure lamp at the scan position. 4. As the image is scanned, the document sheet is fed and ejected by the ADF feed-out roll assembly and ADF exit roll assembly that are driven by the ADF transport motor. 5. When the trail edge of the first document sheet has passed through the sensor (sheet through), the feed of the second document sheet starts.

Duplex document

For duplex document sheets, feed is performed in the following sequence: 1. The first document sheet is fed to the ADF transport roll assembly. 2. The document is fed to the ADF registration roll assembly, and then fed to the scan feed reference position. 3. The document sheet is fed at the feed speed corresponding to the selected magnification, and the image on it is scanned with the exposure lamp at the scan position. 4. As the image is scanned on both sides, the document sheet is fed and ejected by the ADF feed-out roll assembly and ADF exit roll assembly that are driven by the ADF transport motor.



Names and functions of components

ADF Sensor (ADF long media)

The document length in the slow scanning direction is detected by this sensor. Sensor (ADF width 1), Sensor (ADF width 2), Sensor (ADF width 3), Sensor (ADF width 3)

The document length in the fast scanning direction is detected by the combination of these three sensors detecting the position of the tray on which the document is set.

Sensor (ADF document set) A sensor that detects the presence or absence of a document on the ADF document tray.

ADF Document Set LED An LED that illuminates when a document is set on the ADF Document Tray.

Switch (ADF top door interlock) A switch that detects whether the ADF top door assembly is open.

ADF controller card assembly A card that controls the ADF unit assembly. The ADF controller card assembly is connected to and controlled by the Scanner controller card assembly.

Sensor (ADF sheet through) The ADF sensor (ADF sheet through) is installed immediately downstream from the Feed/pick roll assembly to detect completion of document feed.

Sensor (ADF 1st scan) The ADF sensor (ADF 1st scan) is installed just upstream of the scanning surface and is used to for scanning timing operations.

Sensor (2nd scan) The ADF sensor (ADF 1st scan) is installed just down stream of the scanning surface and is used to for scanning timing operations.

Sensor (ADF media exit) The sensor (ADF media exit) is used to detect when scanned media has exited the ADF.

ADF feed motor assembly The feed motor assembly is a stepping motor that rotates the pick roll and feed roll in the reverse direction (CCW direction) and rotates the ADF transport roll assembly in the normal direction (CW direction). When this motor rotates in the reverse direction, the ADF transport roll assembly stops.

ADF transport motor The ADF transport motor is a stepping motor that rotates the ADF registration roll assembly, ADF feed-out roll assembly, and ADF exit roll assembly.

ADF pick solenoid assembly This solenoid causes the ADF pick roll to be raised and lowered in order to properly pick the media.

Print Quality Diagnostics Print quality can be very subjective. Be certain to get samples whenever possible of what the customer believes to be the problem. Run your own print samples to verify the problem, and check to make certain that appropriate the paper media that is being used in the printer before you start.



Print quality pages (Prt Quality Pgs) The print quality test pages can be printed from either the Diagnostics mode or Configuration Menu (CONFIG MENU). When printed from the Diagnostic mode, additional information is included, and the print cartridge lockout is bypassed. The print quality pages consist of four pages. Page one contains a mixture of graphics and text. Page two is gray with two one inch black squares located on the bottom right. Page three is solid black page and page four is blank. If duplex is turned on, the pages are duplexed. The Print Quality Test pages are printed in English and must always be printed on letter, legal, or A4 paper.

To run the Print Quality Test Pages, select Prt Quality Pgs from PRINT TESTS. The message Printing Quality Test Pages is displayed. The following is included in the DIAGNOSTICS version of the first print quality test page:

Paper Transport Diagnostics

Paper Rules of Thumb Paper jams and feed problems occur for numerous reasons. Sometimes, failure of the equipment is the cause or it can be the result of other external factors. Before replacing parts for a feed problem, ask these questions:

• Is the customer using a supported media type? This is a common problem. Check the printer specifications if you are not sure.

• Is the customer using a supported media size? Check the printer specifications of you are not sure.

• Is the customer using a supported media weight? This is a common problem. Check the printer specifications of you are not sure.

• Have you tried printing with a fresh ream of paper? Paper that is left out of the package for periods of time can dry out or absorb moisture.

• Have you tried printing from a different input source? This will help narrow down the cause of some problems.

• Is too much paper loaded in the Tray? Make sure the stack height does not exceed the indicated maximum height.

• Is the paper in the Tray wrinkled, creased, damp, or curled? Paper will not feed properly if it is damaged. Try a fresh ream of paper.

• Are different media types and/or weights loaded in the Tray? This will cause misfeeds.

• Is the relative humidity too high? Too low? This can affect the media and/or printer and its ability to feed properly. Check the printer specifications to see if it is located in an ambient environment.

• Is the paper loaded properly in the Tray or option? This is a common problem. Reposition the paper in the Tray or option to make sure that is loaded properly. The paper guides should be flush against the media, but not too tight.

• Are the feed rollers worn because it is time for a maintenance kit? Check the page count of the printer to see if it is time for a maintenance kit to be installed.

• Are there any obstructions in the paper path? If paper, staples, paper clips or other items are left in the printer, they can prevent the media from feeding properly.

Save yourself time and effort and always check these external influences before spending time troubleshooting a supposed equipment failure.

Potential Field Issues The following are items that may generate questions or calls. 1) ADF edge guides should lightly touch media, as scanning.

Paper tray & ADF input recommendations

• Make sure the paper lies flat in the paper tray.

• Do not remove paper trays while the printer is printing.

• Do not load paper trays, the multipurpose feeder, or the envelope feeder while the printer is printing. Load them prior to printing, or wait for a prompt to load them.

• Do not load too much paper. Make sure the stack height does not exceed the indicated maximum height indicated in the tray or input devise.

• Make sure the guides in the paper trays, multipurpose feeder, ADF input devise or envelope feeder are properly positioned and are not pressing too tightly against the paper or envelopes.

• Push all trays in firmly after loading paper.

2) No mixed width medias in ADF

Paper recommendations

• Use only recommended paper or specialty media. For more information, see “Paper types and weights supported by the printer” in the Users Guide

• Do not load wrinkled, creased, damp, bent, or curled paper.

• Flex, fan, and straighten paper before loading it.

• Do not use paper that has been cut or trimmed by hand.

• Do not mix paper sizes, weights, or types in the same stack.

• Make sure all sizes and types are set correctly in the printer control panel menus.

General Notes: Mirrored MVRAM

• NOTE: The generic FRU will mirror and lock during a standard POR. In order to test a generic FRU for diagnostic purposes, you must bring the machine up in the diagnostic mode.

• If a part was locked by a machine but it did not fix the problem, it cannot be used in another

machine. It needs to be sent back for re-certification.
