Paper and specialty media guide
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 60–90‑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.
When in doubt, contact your paper supplier.
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
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).
