Paper guidelines

Selecting the correct paper or specialty media reduces printing problems. For the best print quality, try a sample of the
paper or specialty media before buying large quantities.

Paper characteristics

The following paper characteristics affect print quality and reliability. Consider these characteristics when evaluating
new paper stock.

General information

27

7015

Weight

The printer trays can automatically feed paper weights up to 120‑g/m2 (32‑lb) bond grain long paper. The multipurpose

2

feeder can automatically feed paper weights up to 163‑g/m
60 g/m

2

(16 lb) might not be stiff enough to feed properly, causing jams. For best performance, use 75‑g/m2 (20‑lb)

bond grain long paper. For paper smaller than 182 x 257 mm (7.2 x 10.1 inches), we recommended to use 90 g/m

(43‑lb) bond grain long paper. Paper lighter than

2

(24 lb) or heavier paper.

2

Note: Two‑sided printing is supported only for 60–90‑g/m

(16–24‑lb) bond 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, 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 Sheffield
points; however, smoothness between 150 and 250 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.

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 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.

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 affect 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 affected by the temperature in the printer fuser

General information

28

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

2

(16 to 24 lb) 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 230°C (446°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 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.

General information

29

7015

• 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 office papers

As an environmentally conscious company, Lexmark supports the use of recycled office 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 different temperature and humidity conditions. Lexmark has found no
reason to discourage the use of today's recycled office papers, but 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

2

Recycled paper, paper of lower weight (<60 g/m
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).

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 affect 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 specifically for laser/LED printers. Check with the manufacturer or vendor to ensure that

the envelopes can withstand temperatures up to 220°C (446°F) without sealing, wrinkling, curling excessively, or
releasing hazardous emissions.

• For best performance, use envelopes made from 90 g/m

must not exceed 70 g/m

2

(20 lb bond) weight.

• 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.

2

(24 lb bond) paper or 25% cotton. All‑cotton envelopes

Note: A combination of high humidity (over 60%) and the high printing temperature may wrinkle or seal 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 off 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

31

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, offsetting, 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 device and network settings, information from embedded

solutions, and user data.

The following are the types of memory and the types of data that they store.

• Volatile memory—The printer uses standard Random Access Memory (RAM) to buffer 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, device settings, network information, scanner and
bookmark settings, and embedded solutions.

• Hard disk memory—The printer hard disk is designed for device-specific functionality and cannot be used for

the long‑term storage of data that is not print-related. The hard disk can retain buffered user data from complex
print jobs, form data, and font data.

To erase volatile memory, turn off the printer.

To erase the non-volatile and printer hard disk memory, see the

“Configuration menu” on page 188.

The following parts are capable of storing memory:

• Printer control panel

• UICC (User Interface Controller Card)

• 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.

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.

Check for correct POR functioning of the base printer by observing the following:

1 The control panel indicator light turns on.

2 The control panel display turns on.

3 A splash screen appears on the display.

4 The cooling fan turns on.

6 The main drive motor turns on.

7 The EP drive assembly drives the developer shaft located in the imaging unit.

8 The exit rollers turn.

9 The control panel indicator light blinks.

10 Ready appears on the display.

Using Safe Mode

Safe Mode lets the printer continue to operate in a special limited mode in which it attempts to continue offering 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 402.

• 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.

Paper jams

Avoiding jams

Load paper properly

•

Make sure paper lies flat in the tray.

• Do not remove a tray while the printer is printing.

• Do not load a tray while the printer is printing. Load it before printing, or wait for a prompt to load it.

• Do not load too much paper. Make sure the stack height is below the maximum paper fill indicator.

• Do not slide the paper into the tray. Load paper as shown in the illustration.

Diagnostic information

47

• Make sure the guides in the tray or the multipurpose feeder are properly positioned and are not pressing tightly

against the paper or envelopes.

• Push the tray firmly into the printer after loading paper.

Use recommended paper

•

Use only recommended paper or specialty media.

• 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 tray.

• Make sure the paper size and type are set correctly on the Embedded Web Server or the computer.

7015

Note: Depending on your operating system, access the Paper menu using Local Printer Settings Utility or Printer

Settings.

• Store paper according to manufacturer recommendations.

Understanding jam messages and locations

When a jam occurs, a message indicating the jam location and information to clear the jam appears on the printer
display. Open the doors, covers, and trays indicated on the display to remove the jam.

Notes:

• When Jam Assist is set to On, the printer automatically flushes blank pages or pages with partial prints to the

standard bin after a jammed page has been cleared. Check your printed output stack for discarded pages.

• When Jam Recovery is set to On or Auto, the printer reprints jammed pages. However, the Auto setting does not

guarantee that the page will reprint.
