Paper guidelines
Paper characteristics
Selecting the appropriate media for the printer can help avoid printing problems.
For detailed information about media characteristics, see the Card Stock & Label Guide available on the Lexmark Support
Web site at http://support.lexmark.com.
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 220 g/m2 (16 to 58 lb bond) grain long. Paper lighter than
60 g/m
long paper. For paper smaller than 182 x 257 mm (7.2 x 10.1 in.), we recommend 90 g/m
Note: Duplex is supported only for 63 g/m
Curl
2
might not be stiff enough to feed properly, causing jams. For best performance, use 75 g/m2 (20 lb bond) grain
2
(24 lb) or heavier paper
2
–170 g/m2 (17 lb–45 lb bond) paper.
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 was 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.
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 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. To condition paper before printing, store 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.
Excessive moisture will result in curl after printing.
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 135 g/m
paper. For papers heavier than 135 g/m
2
, use grain short.
2
(16 to 36 lb bond) paper, use grain long
Fiber content
Most high-quality xerographic paper is made from 100% chemically treated wood pulp. 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.
General information

Page 25
5027
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
• 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:
• 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 176 g/m
• 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.

weight paper.
Preprinted papers such as letterhead must be able to withstand temperatures up to 200°C (392°F) without melting or
releasing hazardous emissions.
General information
25
Page 26
5027
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 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.
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
[16 lb bond]) and/or lower caliper (<3.8 mils [0.1 mm]), and 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).
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 184.
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.
Tools required for service
• Flat-blade screwdrivers, various sizes
• #1 Phillips screwdriver, magnetic
• #2 Phillips screwdriver, magnetic

Performing the initial troubleshooting check
Before you start the troubleshooting procedures, perform the following checks:
• 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 control panel turns on.
4 The fuser heater turns on.
Note: The fuser takes longer to warm up from a cold start than a warm start.
5 The control panel LED starts blinking.
6 A splash screen appears on the display. The following errors or messages may appear:
• Close Door or Insert Cartridge appears 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.
5027
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:
• Enable Safe Mode from the Configuration menu, and then POR the printer.
• For 2.4” display models, press the Stop and Back keys, and then POR the printer.
• For 4.3” and 7” display touchscreen models, 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.

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:
1 Print a menu settings page, and then check the life status of all supplies. Any supplies that are low should be replaced.
Be sure to keep the original menu page to restore the customer's custom settings if needed.
2 On the menu page, make sure the following settings are at the default level:
• Color Correction: Set to Auto.
• Print Resolution: Set to 4800 dpi (print quality problems should be checked at different resolution settings).
• Toner Darkness: Set to 4 (default).
• Color Saver: Set to OFF.
• RGB Brightness, RGB Contrast, RGB Saturation: Set to 0.
• Color Balance: Select Reset Defaults to zero out all colors.
• Check the paper type, texture and weight settings against the paper that is loaded in the printer.
3 Inspect the image transfer unit for damage. Replace, if damaged.
4 Inspect the print cartridges for damage. Replace, if damaged.
