Media guidelines
Paper characteristics
The following paper characteristics affect print quality and reliability. Consider these characteristics when
evaluating new paper stock.
• Weight—The printer can automatically feed paper weights from 60 to 176 g/m2 (16 to 47 lb bond) grain
•
•
•
•
•
long. Paper lighter than 75 g/m 2 (20 lb) might not be stiff enough to feed properly, causing jams. For best
performance, use 80 g/m2 (21 lb bond) grain long paper. For paper smaller than 182 x 257 mm (7.2 x 10.1
in.), we recommend 90 g/m2 or heavier paper.
Curl—Curl is the tendency for paper to curl at its edges. Excessive curl can cause paper feeding problems.
Curl can occur after the paper passes through the printer, where it is exposed to high temperatures.
Storing paper unwrapped in hot, humid, cold, or dry conditions, even in the trays, can contribute to paper
curling prior to printing and can cause feeding problems.
Smoothness—Paper smoothness directly affects print quality. If paper is too rough, toner cannot fuse to it
properly. If paper is too smooth, it can cause paper feeding or print quality issues. Always use paper
between 100 and 300 Sheffield points; however, smoothness between 150 and 200 Sheffield points
produces the best print quality.
Moisture content—The amount of moisture in paper affects both print quality and the ability of the printer
to feed the paper correctly. Leave paper in its original wrapper until it is time to use it. This limits the
exposure of paper to moisture changes that can degrade its performance. Condition paper before printing
by storing it in its original wrapper in the same environment as the printer for 24 to 48 hours before printing.
Extend the time several days if the storage or transportation environment is very different from the printer
environment. Thick paper may also require a longer conditioning period.
Grain direction—Grain refers to the alignment of the paper fibers in a sheet of paper. Grain is either grain
long, running the length of the paper, or grain short, running the width of the paper. For 60 to 176 g/m2 (16
to 47 lb bond) paper, use grain long fibers.
Fiber content—Most high-quality xerographic paper is made from 100% chemically treated pulped wood.
This content provides the paper with a high degree of stability resulting in fewer paper feeding problems
and better print quality. Paper containing fibers such as cotton possesses characteristics that can
negatively affect paper handling.
Unacceptable paper
The following paper types are not recommended for use with the printer:
•
•
•
•
•
•
•
Preprinted papers with chemicals that may contaminate the printer
Preprinted papers that can be affected by the temperature in the printer fuser
Coated papers (erasable bond), synthetic papers, thermal papers
Rough-edged, rough or heavily textured surface papers, or curled papers
Recycled papers containing more than 25% post-consumer waste, and weighing more than 80 g/m2
Paper weighing less than 60 g/m2 (16 lb)
Multiple-part forms or documents
1-6 Service Manual
Selecting paper
Using appropriate paper prevents jams and helps ensure trouble-free printing. To help avoid jams and poor print
quality:
• Always use new, undamaged paper.
• Before loading paper, know the recommended print side of the paper. This information is usually indicated
on the paper package.
• Do not use paper that has been cut or trimmed by hand.
• Do not mix paper sizes, types, or weights in the same source; mixing results in jams.
• Do not use coated papers unless they are specifically designed for electrophotographic printing.
Selecting preprinted forms and letterhead
Use these guidelines when selecting preprinted forms and letterhead:
• Use grain long for 60 to 176 g/m2 weight paper.
• Use only forms and letterhead printed using an offset lithographic or engraved printing process.
• Avoid papers with rough or heavily textured surfaces.
Use papers printed with heat-resistant inks designed for use in xerographic copiers. The ink must be able to
withstand temperatures up to 200°C (392°F) without melting or releasing hazardous emissions. Use inks that
are not affected by the resin in toner. Inks that are oxidation-set or oil-based generally meet these requirements;
latex inks might not. When in doubt, contact the paper supplier.
Preprinted papers such as letterhead must be able to withstand temperatures up to 200°C (392°F) without
melting or releasing hazardous emissions.
Storing paper
Use these paper storage guidelines to help avoid jams and uneven print quality:
• For best results, store paper where the temperature is 21°C (70°F) and the relative humidity is 40%. Most
•
•
•
label manufacturers recommend printing in a temperature range of 18 to 24°C (65 to 75°F) with relative
humidity between 40 and 60%.
Store paper in cartons when possible, on a pallet or shelf, rather than on the floor.
Store individual packages on a flat surface.
Do not store anything on top of individual paper packages.
Using recycled paper and other office papers
Generally the following property guidelines apply to recycled paper.
• Low moisture content (4–5%)
• Suitable smoothness (100–200 Sheffield units, or 140–350 Bendtsen units, European)
•
•
Note: Some much smoother papers (such as premium 24 lb laser papers, 50–90 Sheffield units) and
much rougher papers (such as premium cotton papers, 200–300 Sheffield units) have been engineered to
work very well in laser printers, despite surface texture. Before using these types of paper, consult your
paper supplier.
Suitable sheet-to-sheet coefficient of friction (0.4–0.6)
Sufficient bending resistance in the direction of feed
Recycled paper, paper of lower weight (<60 g/m2 [16 lb bond]) and/or lower caliper (<3.8 mils [0.1 mm]), and
paper that is cut grain-short for portrait (or short-edge) fed printers may have lower bending resistance than is
required for reliable paper feeding. Before using these types of paper for laser (electrophotographic) printing,
consult your paper supplier. Remember that these are general guidelines only and that paper meeting these
guidelines may still cause paper feeding problems in any laser printer (for example, if the paper curls excessively
under normal printing conditions).

2. Diagnostics information
Start
CAUTION: Unplug power from the printer before connecting or disconnecting any cable,
assembly, or electronic card. This is a precaution for personal safety and to prevent damage to the
printer.
Use the service error code, user status message, user error message, symptom table, service checks, and
diagnostic aids in this chapter to determine the corrective action necessary to repair a malfunctioning printer.
They will lead you to solutions or service checks, including use of various tests.
Symptom tables
If your machine completes the “Power–On Self Test (POST) sequence” on page 2-1 without an error and you
have a symptom, then go to “Service error codes” on page 2-26. Locate your symptom, and take the
appropriate action.
Service errors (8xx.xx / 9xx.xx’s)
If a service error code appears while you are working on the machine, then go to “Service error codes” on
page 2-26, and take the indicated action for that error.
Service error codes are indicated by a three-digit error code followed by a period and additional numbers in the
format XXX.YY. In most cases, five digits are shown.
User status and attendance messages
• User status messages provide the user with information on the current status of the printer. Ready displays
•
on the first line of the display unless invoked, and then Power Saver displays. If a user status message is
displayed, then go to “Service error codes” on page 2-26.
User attendance messages are indicated by a two- or three-digit error code that provides the user with
information that explains a problem with a print cartridge, paper jam, option, port, and so on. If a user error
message displays, then go to “User attendance messages” on page 2-13 and “Paper jam error codes
(200-series)” on page 2-20.
Power–On Self Test (POST) sequence
The following is an example of the events that occur during the POR sequence when the printer is turned on.
1. Display screen illuminates and the memory test is initiated.
2. The Dell splash screen is displayed with a progress bar. The firmware revision is displayed in the lower
left of the screen.
3. Scanner calibration and testing initiates when the progress bar is two thirds finished.
4. Not Ready will be displayed if the cover is open.
5. Any cartridge errors, such as Defective Cartridge, are displayed in the message are at the bottom of the

Held jobs may not be
restored (Config Change
57)
This message is only posted once after the firmware has tried to restore all of the
jobs on disk, regardless of the number of held jobs that were not restored.
There are three versions of this IR, depending upon cause. IRHeldC occurs when
the printer could not restore jobs from the disk because the configuration of the
printer has changed. Some of these said configuration changes are code version
changes, paper handling option(s) removed, or the disk was moved from a
different model or speed of printer.

35 RES Save Off
Deficient Memory
Explanation
This message displays when the printer lacks sufficient memory to enable
Resource Save. This message usually indicates the user has allocated too much
memory for one or more of the printer link buffers; however, modification of other
printer settings which affect the amount of available memory may also create this
condition. If restoration of Resource Save is required after this message is
received, the customer should install additional memory or set each link buffer to
Auto. Once all link buffers are returned to Auto, you should exit the menu to
activate the link buffer changes. Once the printer returns to the Ready state, you
can enable Resource Save and go back and modify the link buffers again. Note
the reduction of available memory to the link buffers when Resource Save has
been enabled, and compare it to the memory available when Resource Save is
disabled.

200.00
Paper jam around input sensor.
Remove the PC kit and paper or debris at the input
sensor.
200.01
Classic input jam. The media is too long over the input
sensor. Possible causes include multi-sheet feed, tray
size sensing problem, and media slippage.
200.02
The main input sensor never became uncovered from
the sheet ahead.
First, remove the PC kit and paper or debric at the
input sensor. Then, inspect the flag on the input
sensor. It should rotate freely. Replace the sensor if
necessary. Finally, check the paper size settings in
the printer and the driver.
200.03
The video never started on the page at the input
sensor within two inches after hitting the input sensor
Check the printhead. See “Printhead service
check” on page 2-54.
200.04
The media at the input sensor before interrupt
occurred–not enough time elapsed since the printhead
started to expect the printhead mirror motor lock.
Possible causes include bouncy sensor or
exceptionally fast pick– perhaps due to media prestaged in the source tray.
Carefully remove the tray and notice if the leading
edge of the media is pointed upward and out of the
tray. If so, then inspect the tray wear strips and
replace if necessary.
200.06
Imaged page not expected page (bouncy passthru
sensor)
Remove the toner cartridge/PC kit. At the front,
remove the upper front guide, and inspect the flag on
the manual input sensor. If the flag is loose, then
replace it. See “Media manual input sensor” on

Possible causes include multi-sheet feed, media size
(length) problem, pre-staged media in the tray.
Verify that the media is approved. Inspect the wear
strips in the tray, and replace if they are worn.
200.22
FAILED SMALL GAP OR NO GAP JAM RECOVERY.
Engine detected small gap or no gap at the manual
feeder sensor, opened the gap by stopping the feed
rolls, but never saw the leading edge of the second
page at the input sensor.
200.23
Laser Servo never started due to potential conflict with
the transfer servo. Possible causes: slow or missing
transport motor positional feedback, or the media is
transferred too quickly to the input sensor.
200.24
The measured gap at the input sensor is too small to
meet the video delivery requirements. (There is not
enough time since prior image finished to start new
image)
200.26
The trailing edge never cleared the input sensor when
feeding out the media that was detected during warmup.
200.27

Service checks
Service checks which involve measuring voltages on the LVPS/HVPS (low voltage power supply/
high voltage power supply board) should be performed with the printer positioned on its back side.
Note: When making voltage readings, always use frame ground unless another ground is
specified. See the wiring diagram in the back of the book for more information.
Note: The controller board is located beneath the flatbed. To access the controller board, see “ADF unit
removal” on page 4-85.

POST (Power-On Self Test)
Note: The printer should complete POST in approximately 45 seconds.
If the printer fails to display lights or activate the drive motor, fuser, or fan, then check the
following order:
1. Power to the LVPS/HVPS.
2. Power from the LVPS/HVPS to the engine board. See “Engine board service check”
on page 2-36.
3. Power from the engine board to the controller board.
4. Cables are plugged in correctly, especially for the operator panel. The printer will not
power-up without a functioning operator panel.
5. The operator panel. See “Operator panel service check” on page 2-43.
Verify +24 V dc and +5V dc input from the engine board.
1. Turn the printer off.
2. Disconnect the controller board power cable from the engine board at J503.
3. Turn the printer on.
4. Verify +24 V dc on positions 17, and 19 of the cable connector (J503).
5. Verify +5 V dc on positions 11, 13, 15 on J503.
6. If voltages are correct on the engine board, then check the continuity in the other
conductors of the cable. If the cable is good, then turn the printer off, and check the
connectors on the controller board. If the cable isn’t good, replace the controller board
cable.

Banding appears as light or dark horizontal lines on a uniformly gray page or on a page with
a large area of graphics. Banding is primarily due to a variation in the speed of the media as
it feeds through the printer, especially in the developer and transfer process. It may also be
a result of overly dry or moist environments.
With the printer off, check to make sure that the laser beam is not blocked.
Inspect the toner cartridge and paper feed components, especially the drive coupler and
drive gears for debris, binds, or damage.

The setting adjusts the minimum gap between sheets. Increasing this value may reduce curl of some printed
media and eliminate some output bin stacking problems. However, increasing this value also results in slower
overall performance, measured in pages per minute. The range of values is 0 to 255, and the default value is 0.

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.) For example, if the
right margin setting on the page is -2, and the number that is closest to the darkest line on the graph is 3
(-2+3), then the right margin setting will be equal to +1.
6. Press
3-38 Service Manual
or
to the desired setting, and press
.
7. 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 5.
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.
Printhead assembly mechanical adjustment
A printhead needs to be correctly positioned after it has been removed. Use a pencil to mark the screw locations
of the old printhead on the metal frame. Align the new printhead relative to the location of the old printhead.
Note: Skew is caused by a sheet being fed through the printer while misaligned. The entire image is rotated
relative to the sheet edges. However, a mechanically misaligned printhead causes the horizontal lines to appear
skewed, while the vertical lines remain parallel to the vertical edges. There are no adjustments for skew. Check
the pick roll (paper pick assembly) for wear, the paper path for obstructions, the fuser for proper setting, and the
tray paper guides for fit to the media.

Paper jams
Avoiding jams
Most paper jams can be avoided by correctly loading paper and specialty media in the printer.
The following hints can help prevent paper jams:
• Use only the recommended print media.
• Do not overload the print media sources. Make sure the stack height does not exceed the maximum height
indicated by the stack line on the labels in the sources.
• Do not load wrinkled, creased, damp, or curled print media.
• Flex, fan, and straighten print media before loading it. If jams do occur with the print media, then try feeding
one sheet at a time through the manual feeder.
• Do not mix print media sizes, weights, or types in the same print media source.
• Push all trays in firmly after loading them.
Note: Make sure the media stack is below the maximum media fill indicators on the 250-sheet tray before
pushing the tray into the printer.
•
•
•
•
•
Make sure paper guides are positioned before loading the paper or specialty media.
Do not remove trays while a job is printing.
Before loading transparencies, fan the stack to prevent sheets from sticking together.
Do not use envelopes that:
– Have excessive curl
– Are stuck together
– Are damaged in any way
– Contain windows, holes, perforations, cutouts, or embossments
– Have metal clasps, string ties, or metal folding bars
– Have postage stamps attached
– Have any exposed adhesive when the flap is in the sealed position
Use only recommended media. Refer to the User Guide for more information about which media
provides optimum results for the current printing environment.

Warning: Read the following before handling electronic parts.
Handling ESD-sensitive parts
Many electronic products use parts that are known to be sensitive to electrostatic discharge (ESD). To prevent
damage to ESD-sensitive parts, follow the instructions below in addition to all the usual precautions, such as
turning off power before removing logic cards:
• Keep the ESD-sensitive part in its original shipping container (a special “ESD bag”) until the
part is ready to be installed into the printer.
• Make the least-possible body movements to prevent an increase of static electricity from
clothing fibers, carpets, and furniture.
• Put the ESD wrist strap on your wrist. Connect the wrist band to the system ground point. This
discharges any static electricity in your body to the printer.
• Hold the ESD-sensitive part by its edge connector shroud (cover); do not touch its pins. If a
pluggable module is being removed, then use the correct tool.
• Do not place the ESD-sensitive part on the MFP cover or on a metal table; if the ESDsensitive part needs to be put down for any reason, then first put it into its special bag.
• Machine covers and metal tables are electrical grounds. They increase the risk of damage,
•
•
•
because they make a discharge path from your body through the ESD-sensitive part. (Large
metal objects can be discharge paths without being grounded.)
Prevent ESD-sensitive parts from being accidentally touched by other personnel. Install
machine covers when the machine is not being worked on, and do not put unprotected ESDsensitive parts on a table.
If possible, keep all ESD-sensitive parts in a grounded metal cabinet (case).
Be extra careful in working with ESD-sensitive parts when cold-weather heating is used,
because low humidity increases static electricity.
Repair information

Removal procedures
• Remove the toner cartridge and media tray before removing other printer parts. The toner cartridge should
•
•
•
•
4-2
be protected from light while out of the printer.
We recommend disconnecting all external cables from the printer to prevent damage during service.
Unless otherwise stated, reinstall the parts in reverse order of removal.
When reinstalling a part held with several screws, start all screws before final tightening.
Remove the paper tray and print cartridge before proceeding with a removal.
ACM pick tire roller removal
1. Place the printer on its side.
Note: Be careful to not mar the finish of the printer.
2. Open the duplex jam door just far enough to pull out the ACM pick tires.
Warning: Open the duplex door only far enough to remove the ACM pick tires. If the door is opened too
far, then it can become disengaged and interfere with the paper tray. The tray may go in but will not come
out, and will render the printer non-serviceable.
3. After the ACM pick tires have been pulled out, close the duplex door.

6. Preventive maintenance
This chapter describes procedures for printer preventive maintenance. Follow these recommendations to help
prevent problems and maintain optimum performance.
Safety inspection guide
The purpose of this inspection guide is to aid you in identifying unsafe conditions.
If any unsafe conditions exist, then find out how serious the hazard could be and if you can continue before you
correct the hazard.
Check the following items:
• Damaged, missing, or altered parts, especially in the area of the On/Off switch and the power supply
• Damaged, missing, or altered covers, especially in the area of the top cover and the power supply cover
• Possible safety exposure from any non-Dell attachments
Lubrication specifications
FRUs are typically lubricated as needed from the factory. If not, then lubricate only when parts are replaced or as
needed, not on a scheduled basis. Use of lubricants other than those specified can cause premature failure.
Some unauthorized lubricants may chemically attack parts. Use P/N 99A0394 (Nyogel 744) to lubricate
appropriate areas. Lubricate gears that were lubricated in the original part.
Scanner glass cleaning
Kit 40X0392 is available for cleaning the scanner glass on the flatbed. Included are instructions for cleaning the
ADF glass if streaks should appear on copies from the ADF.
Maintenance kits
Maintenance kits include:
•
