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 aects print quality. If paper is too rough, then toner cannot fuse to it properly. If
paper is too smooth, then it can cause paper feeding or print quality issues. Always use paper between 100
and 300 Sheeld points; however, smoothness between 150 and 250 Sheeld points produces the best print
quality.
Moisture content
The amount of moisture in paper aects 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.
Store paper in its original wrapper in the same environment as the printer for 24 to 48 hours before printing.
Extend the time to several days if the storage or transportation environment is very dierent 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.
2
For 60–90‑g/m
(16–24‑lb) bond paper, grain long paper is recommended.
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 can negatively aect paper handling.
Unacceptable paper
The following paper types are not recommended for use with the printer:
• Chemically‑treated papers used to make copies without carbon paper, also known as carbonless papers,
carbonless copy paper (CCP), or no carbon required (NCR) paper
• Preprinted papers with chemicals that may contaminate the printer
• Preprinted papers that can be aected by the temperature in the printer fuser
General information
30
Page 31
7015
• Preprinted papers that require a registration (the precise print location on the page) greater than ±2.4 mm
(±0.9 inch), such as optical character recognition (OCR) forms
In some cases, registration can be adjusted with a software application to successfully print on these forms:
• Coated papers (erasable bond), synthetic papers, thermal papers
• Rough‑edged, rough or heavily textured surface papers, or curled papers
• Recycled papers that fail EN12281:2002 (European)
• Paper weighing less than 60 g/m
2
(16 lb)
• Multiple‑part forms or documents
Selecting paper
Using the appropriate paper prevents jams and helps ensure trouble‑free printing.
To help avoid paper jams and poor print quality:
• Always use new, undamaged paper.
• Before loading paper, know the recommended printable 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 tray; 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 90 g/m
• Use only forms and letterhead printed using an
2
(16 to 24 lb) weight paper.
lithographic or engraved printing process.
oset
• 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 230°C (446°F) without melting or releasing hazardous emissions. Use inks that
are not aected 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 230°C (446°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 percent.
Most label manufacturers recommend printing in a temperature range of 18–24°C (65–75°F) with relative
humidity between 40 and 60 percent.
• Store paper in cartons, 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.
• Take paper out of the carton or wrapper only when you are ready to load it in the printer. The carton and
wrapper help keep the paper clean, dry, and flat.

Using recycled paper and other oce papers
As an environmentally conscious company, Lexmark supports the use of recycled oce paper produced
specifically for use in laser (electrophotographic) printers. In 1998, Lexmark presented to the US government
a study demonstrating that recycled paper produced by major mills in the US fed as well as non-recycled paper.
However, no blanket statement can be made that all recycled paper will feed well.
Lexmark consistently tests its printers with recycled paper (20–100% post-consumer waste) and a variety of
test paper from around the world, using chamber tests for dierent temperature and humidity conditions.
Lexmark has found no reason to discourage the use of today's recycled oce papers, but generally the following
property guidelines apply to recycled paper.
• Low moisture content (4–5%)
• Suitable smoothness (100–200
Note: Some much smoother papers (such as premium 24 lb laser papers, 50–90 Sheeld units) and
much rougher papers (such as premium cotton papers, 200–300

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,

Using specialty media
Tips on using card stock
Card stock is heavy, single‑ply specialty media. Many of its variable characteristics, such as moisture content,
thickness, and texture, can significantly impact print quality. Print samples on the card stock being considered
for use before buying large quantities.
• From the Paper menu, set the Paper Type to Card Stock.
• Select the appropriate Paper Texture setting.
• Be aware that preprinting, perforation, and creasing may significantly aect the print quality and cause jams
or other paper handling problems.
• Check with the manufacturer or vendor to ensure the card stock can withstand temperatures up to 220°C
(446°F) without releasing hazardous emissions.
• Do not use preprinted card stock manufactured with chemicals that may contaminate the printer. Preprinting
introduces semi‑liquid and volatile components into the printer.
• Use grain short card stock when possible.

Tips on using envelopes
Print samples on the envelopes being considered for use before buying large quantities.
• Use envelopes designed
that the envelopes can withstand temperatures up to 220°C (446°F) without sealing, wrinkling, curling
excessively, or releasing hazardous emissions.
specifically
• For best performance, use envelopes made from 90 g/m
envelopes must not exceed 70 g/m
• Use only new envelopes from undamaged packages.
• To optimize performance and minimize jams, do not use envelopes that:
– Have excessive curl or twist
– Are stuck together or damaged in any way
– Have windows, holes, perforations, cutouts, or embossing
– Have metal clasps, string ties, or folding bars
– Have an interlocking design
– Have postage stamps attached
– Have any exposed adhesive when the flap is in the sealed or closed position
– Have bent corners
– Have rough, cockle, or laid finishes
• Adjust the width guides to fit the width of the envelopes.

Tips on using labels
Print samples on the labels being considered for use before buying large quantities.
Note: Use only paper label sheets. Vinyl, pharmacy, and two‑sided labels are not supported.
For more information on label printing, characteristics, and design, see the Card Stock & Label Guide available
at
http://support.lexmark.com.
When printing on labels:
• Use labels designed specifically for laser printers. Check with the manufacturer or vendor to verify that:
– The labels can withstand temperatures up to 230°C (446°F) without sealing, excessive curling, wrinkling,
or releasing hazardous emissions.
– Label adhesives, face sheet (printable stock), and topcoats can withstand up to 25‑psi (172‑kPa) pressure
without delaminating, oozing around the edges, or releasing hazardous fumes.
• Do not use labels with slick backing material.
• Use full label sheets. Partial sheets may cause labels to peel o during printing, resulting in a jam. Partial
sheets also contaminate the printer and the cartridge with adhesive, and could void the printer and toner
cartridge warranties.
• Do not use labels with exposed adhesive.
• Do not print within 1 mm (0.04 inches) of the edge of the label, of the perforations, or between die‑cuts of
the label.
General information
33
Page 34
7015
• Make sure the adhesive backing does not reach to the edge of the sheet. Zone coating of the adhesive
should be at least 1 mm (0.04 inches) away from edges. Adhesive material contaminates the printer and
could void the warranty.
• If zone coating of the adhesive is not possible, then remove a 2‑mm (0.06‑inches) strip on the leading and
driver edge, and use a non‑oozing adhesive.
• Portrait orientation is recommended, especially when printing bar codes.
Tips on using letterhead
• Use letterhead designed specifically for laser printers.
• Print samples on the letterhead being considered for use before buying large quantities.
• Before loading letterhead, flex, fan, and straighten the stack to prevent sheets from sticking together.
• Page orientation is important when printing on letterhead.
Tips on using transparencies
• Print a test page on the transparencies being considered for use before buying large quantities.
• Feed transparencies from the standard tray, or the multipurpose feeder.
• Use transparencies designed specifically for laser printers. Transparencies must be able to withstand
temperatures up to 185°C (365°F) without melting, discoloring, osetting, or releasing hazardous emissions.
Note: If the transparency weight is set to Heavy and the transparency texture is set to Rough in the Paper
menu, then transparencies can be printed at a temperature up to 195°C (383°F).
• Avoid getting fingerprints on the transparencies to prevent print quality problems.
• Before loading transparencies, flex, fan, and straighten the stack to prevent sheets from sticking together.

Data security notice
1 The printer contains various types of memory that store printer and network settings, information from
embedded solutions, and user data.
The following are the types of memory and data that they store.
• Volatile memory—The printer uses standard random access memory (RAM) to buer user data
temporarily during simple print and copy jobs.
• Non-volatile memory—The printer may use two forms of non-volatile memory: EEPROM and NAND
(flash memory). Both types are used to store the operating system, printer settings, network information,
scanner and bookmark settings, and embedded solutions.
• Hard disk memory—The printer hard disk is designed for printer-specific functionality and cannot be
used for the long‑term storage of data that is not print-related. The hard disk can retain buered user
data from complex print jobs, form data, and font data.
To erase volatile memory, turn o the printer.
To erase the non-volatile and printer hard disk memory, see
“Configuration menu” on page 198.
The following parts are capable of storing memory:
• Printer control panel
• User interface controller card (UICC)
• Controller board
• Optional hard disk
Note: The control panel and controller board contain NVRAM.
2 After removing the old part, return it to your next level of support.

Diagnostic information
CAUTION—SHOCK HAZARD: Remove the power cord from the electrical outlet before you connect or
disconnect any cable or electronic card or assembly for personal safety and to prevent damage to the
printer. Disconnect any connections between the printer and PCs/peripherals.
CAUTION—POTENTIAL INJURY: The printer weight is greater than 18kg (40 lb) and requires two or
more trained personnel to lift it safely. Use the hand holds on the side of the printer. Make sure your
fingers are not under the printer when you lift or set the printer on the floor or another stable surface.
CAUTION—HOT SURFACE: The inside of the printer might be hot. To reduce the risk of injury from a hot
component, allow the surface to cool before touching it.
Troubleshooting overview
Performing the initial troubleshooting check
Before you start the troubleshooting procedures, perform the following checks:
7015
• With the power cord unplugged from the electrical outlet, check that the cord is free from the breakage,
short circuits, disconnected wires, or incorrect connections.
• Make sure the printer is properly grounded. Check the power cord ground terminal.
• Make sure the power supply line voltage is within 10% of the rated line voltage.
• Make sure the machine is securely installed on a level surface in a well‑ventilated area.
• Make sure the room temperature is between 16 and 32°C (60 and 90°F) and that the relative humidity is
between 20 and 80%.
• Avoid sites generating ammonia gas, high temperature, high humidity (near water faucets, kettles,
humidifiers), cold spaces, near open flames, and dusty areas.
• Avoid sites exposed to direct sunlight.
• Make sure the paper is the recommended paper for this printer.
• Make a trial print with paper from a newly opened package, and check the result.
Power‑on Reset (POR) sequence
When you turn on the printer, it performs a POR sequence.

Using Safe Mode
Safe Mode lets the printer continue to operate in a special limited mode in which it attempts to continue oering
as much functionality as possible despite known issues.
Warning—Potential Damage: Safe Mode is intended as a short‑term workaround and should be used only in
the case of a non‑critical error when a print job must be completed before service can be arranged to repair
the printer. The printer must be returned to standard operating mode before diagnostics can be run or
full‑function printing can continue.
You can enter Safe Mode in one of the following ways:
• Enable Safe Mode from the Configuration menu, and then POR the printer.
• Press the Stop and Back keys, and then POR the printer.
Return the printer to standard operating mode to service the printer and return to full‑function printing.

Fixing print quality issues
The symptoms described in this chapter might require replacement of one or more CRUs (Customer
Replaceable Units) designated as supplies or maintenance items, which are the responsibility of the customer.
With the customer's permission, you might need to install a developer (toner) cartridge.
Initial print quality check
Before troubleshooting specific print problems, complete the following initial print quality check:
• The printer must be in a location that follows the recommended operating environment specifications.
See
“Operating environment” on page 410.
• Check the life status of all supplies. Any supply that is low should be replaced.
• Load 20‑lb plain letter or A4 paper. Make sure the paper guides are properly set and locked. From the
control panel, set the paper size and type to match the paper loaded in the tray.
• Print a menu settings page. Be sure to keep the original menu settings page to restore the customer’s
custom settings if needed.
• Verify on the menu settings page if the following are set to their default values:
– Print resolution: 600 dpi
– Toner darkness: 8
• Check the transfer roll for damage. Replace if damaged.
• Check the toner cartridge and imaging unit for damage. Replace if damaged.
• Print the print quality pages to see if the problem remains. Use Tray 1 to test print quality problems.
• Print a print quality test page, and then look for variations in the print from what is expected. Verify if the
settings under EP Setup are set to their default values. See
• Check to ensure the correct printer driver for the installed software is being used. An incorrect printer
driver for the installed software can cause problems. Incorrect characters could print, and the copy may
not fit the page correctly.
