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.
