Paper guidelines
Paper characteristics
The following paper characteristics affect print quality and reliability. Consider these factors before printing on them:
General information
47
Page 48
7463
Weight
The printer trays and multipurpose feeder can automatically feed paper weights between 60–176 g/m2 (16–47‑lb) grain
2
long paper. The 2100‑sheet tray can automatically feed paper weights up to 60–135 g/m
Paper lighter than 60 g/m
Note: Two‑sided printing is supported for 60–176 g/m
2
(16 lb) might not be stiff enough to feed properly, and may cause jams.
2
(16–47‑lb) paper.
(16–36‑lb) grain long 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;
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 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 60–176 g/m
(16–47‑lb) 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.
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.
General information
48
Page 49
7463
• 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 grain long for 60–90‑g/m
• Use only forms and letterhead printed using an offset lithographic or engraved printing process.
• Avoid paper with rough or heavily textured surfaces.
• 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.
• Print samples on preprinted forms and letterheads considered for use before buying large quantities. This
determines whether or not the ink in the preprinted form or letterhead will affect print quality.
• When in doubt, contact your paper supplier.
2
(16–24‑lb) paper.
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 office papers
As an environmentally conscientious company, Lexmark supports the use of recycled paper produced specifically for
use in laser (electrophotographic) printers.
While no blanket statement can be made that all recycled paper will feed well, Lexmark consistently tests papers that
represent recycled cut size copier papers available on the global market. This scientific testing is conducted with rigor
and discipline. Many factors are taken into consideration both separately and as a whole, including the following:
• Amount of post-consumer waste (Lexmark tests up to 100% post-consumer waste content.)
• Temperature and humidity conditions (Testing chambers simulate climates from all over the world.)
• Moisture content (Business papers should have low moisture: 4–5%.)
• Bending resistance and proper stiffness means optimum feeding through the printer.
• Thickness (impacts how much can be loaded into a tray)
• Surface roughness (measured in Sheffield units, impacts print clarity and how well toner fuses to the paper)
• Surface friction (determines how easily sheets can be separated)
• Grain and formation (impacts curling, which also influences the mechanics of how the paper behaves as it moves
through the printer)
• Brightness and texture (look and feel)
General information
49
Page 50
7463
Recycled papers are better than ever; however, the amount of recycled content in a paper affects the degree of control
over foreign matter. And while recycled papers are one good path to printing in an environmentally responsible manner,
they are not perfect. The energy required to de-ink and deal with additives such as colorants and “glue” often generates
more carbon emissions than does normal paper production. However, using recycled papers enables better resource
management overall.
Lexmark concerns itself with the responsible use of paper in general based on life cycle assessments of its products. To
gain a better understanding of the impact of printers on the environment, the company commissioned a number of
life cycle assessments and found that paper was identified as the primary contributor (up to 80%) of carbon emissions
caused throughout the entire life of a device (from design to end-of-life). This is due to the energy-intensive
manufacturing processes required to make paper.
Thus, Lexmark seeks to educate customers and partners on minimizing the impact of paper. Using recycled paper is
one way. Eliminating excessive and unnecessary paper consumption is another. Lexmark is well-equipped to help
customers minimize printing and copying waste. In addition, the company encourages purchasing paper from suppliers
who demonstrate their commitment to sustainable forestry practices.
Lexmark does not endorse specific suppliers, although a converter’s product list for special applications is maintained.
However, the following paper choice guidelines will help alleviate the environmental impact of printing:
1 Minimize paper consumption.
2 Be selective about the origin of wood fiber. Buy from suppliers who carry certifications such as the Forestry
Stewardship Council (FSC) or The Program for the Endorsement of Forest Certification (PEFC). These certifications
guarantee that the paper manufacturer uses wood pulp from forestry operators that employ environmentally and
socially responsible forest management and restoration practices.
3 Choose the most appropriate paper for printing needs: normal 75 or 80 g/m
or recycled paper.
2
certified paper, lower weight paper,
Unacceptable paper examples
Test results indicate that the following paper types are at risk for use with laser printers:
• Chemically treated papers used to make copies without carbon paper, also known as carbonless papers
• Preprinted papers with chemicals that may contaminate the printer
• Preprinted papers that can be affected by the temperature in the printer fuser
• Preprinted papers that require a registration (the precise location on the page) greater than ± 2.3 mm (± 0.9 in.),
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 testing)
• Paper weighing less than 60 g/m
• Multiple part forms or documents

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 affect print quality.
• From the printer control panel, set the paper size, type, texture, and weight in the Paper menu to match the card
stock loaded in the tray.
• Print samples on the card stock being considered for use before buying large quantities.
• Specify the paper texture and weight from the tray settings to match the paper loaded in the tray.
• Preprinting, perforation, and creasing may significantly affect the print quality and cause jams or other paper feed
problems.
• Before loading the card stock on the tray, flex and fan the card stock to loosen them. Straighten the edges on a
level surface.
Tips on using envelopes
• From the printer control panel, set the paper size, type, texture, and weight in the Paper menu to match the
envelopes loaded in the tray.
• Print samples on the envelopes being considered for use before buying large quantities.
• Use envelopes designed specifically for laser printers.
• For best performance, use envelopes made from 90‑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.
• Before loading the envelopes on the tray, flex the stack of envelopes back and forth to loosen them, and
then fan them. Straighten the edges on a level surface.
2
(24‑lb) paper or 25% cotton.
Note: A combination of high humidity (over 60%) and high printing temperature may wrinkle or seal envelopes.
Tips on using labels
• From the printer control panel, set the paper size, type, texture, and weight in the Paper menu to match the labels
loaded in the tray.
• Print samples on labels being considered for use before buying large quantities.
General information
51
Page 52
• For more information on label printing, characteristics, and design, see the Card Stock & Label Guide at
http://support.lexmark.com.
• Use labels designed specifically for laser printers.
• 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.
• Before loading labels on the tray, flex and fan labels to loosen them. Straighten the edges on a level surface.
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 and fan the sheets to prevent them from sticking together.
• Page orientation is important when printing on letterhead.

Tips on using transparencies
• From the printer control panel, set the paper size, type, texture, and weight in the Paper menu to match the
transparencies loaded in the tray.
• Print a test page on the transparencies being considered for use before buying large quantities.
• Use transparencies designed specifically for laser printers.
• Avoid getting fingerprints on the transparencies to prevent print quality problems.
• Before loading transparencies, flex and fan the sheets to prevent them from sticking together.
• When printing on large volumes of transparencies, make sure to print by batches of only up to 20 with an interval
of at least three minutes between batches, to prevent the transparencies from sticking together in the bin. You can
also remove transparencies from the bin by batches of 20.

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 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, printer settings, network information, scanner
and bookmark settings, and embedded solutions.
General information
57
Page 58
• 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 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 following parts are capable of storing memory:
“Configuration menu” on page 356.
• 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.

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 18 kg (40 lb) and requires two or more
trained personnel to lift it safely.
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.
Troubleshooting overview
Performing the initial troubleshooting check
Before you start the troubleshooting procedures, perform the following checks:
7463
• 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 LED turns on.
2 The main fan turns on.
3 The operator panel turns on.
4 The fuser heater turns on. The fuser takes longer to warm up from a cold start than a warm start.
5 The operator panel LED starts blinking.

6 A splash screen appears on the display. The following errors or messages may appear:
• Close Door or Insert Cartridge appear if the front access door is open or the print cartridge is missing
• Cartridge errors, such as Defective Cartridge or Missing Cartridge
7 Ready appears on the display.
8 The main drive motor turns on.
9 The EP drive assembly drives the developer shaft located in the print cartridge.
10 The exit rollers turn.
11 The printer may begin calibration.
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:
• Enter Safe Mode from the Configuration menu, and then POR the printer. See “Safe Mode” on page 360.
• Press the 6 and 7 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
“Environment” on page 1010.
• 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
“EP Defaults” on page 351.
• 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.

• 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
75
Page 76
7463
• 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.
• If you are loading prepunched paper for use with the staple finisher, then make sure the holes on the long edge of
the paper are on the right side of the tray. For more information, see the “Loading paper and specialty media”
section of the User’s Guide.
Allow the paper to enter the optional mailbox bins properly (MX81x only)
•
Make sure to adjust the bin extender so that the paper size indicators match the size of the paper used.
Notes:
– If the bin extender is shorter than the size of the paper you are printing on, then the paper causes a jam in
the mailbox bin. For example, if you are printing on a legal-size paper and the bin extender is set to lettersize, then a jam occurs.
– If the bin extender is longer than the size of the paper you are printing on, then the edges become uneven
and the paper is not stacked properly. For example, if you are printing on a letter-size paper and the bin
extender is set to legal-size, then the paper does not stack properly.
Diagnostic information

Page 77
7463
• If paper needs to be returned to the mailbox bin, then insert the paper under the bin arm, and then push the paper
all the way back.
Note: If the paper is not under the bin arm, then a jam occurs due to an overfilled bin.
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 or specialty media 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 computer or printer control panel.
• Store paper per 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.
