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/m

long. Paper lighter than 75 g/m
performance, use 80 g/m
in.), we recommend 90 g/m

• 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/m
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.

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/m

2

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

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

General information 1-7

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

Note: The Event log (See “EVENT LOG” on page 3-32) will list any of these errors that have occurred.

Repeating jams or jam messages can be caused by any of the following:

• Faulty/contaminated pick solenoids or worn cams of the solenoids.

• Faulty/contaminated flags or springs.

• Debris in the paper path.

• Media not of the specified length.

Error Description Action

200.00 Paper jam around input sensor. Remove the PC kit and paper or debris at the input

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.

sensor within two inches after hitting the input sensor

200.04 The media at the input sensor before interrupt

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

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.

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.
