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.

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.

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

(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.

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.
