Paper and specialty media guide 38 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 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) • 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 (

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
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)
•
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 gm
2
/16 lb bond) and/or lower caliper (<3.8 mils/0.1 mm), and 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.
Using letterhead
Check with the manufacturer or vendor to determine whether the chosen preprinted letterhead is acceptable for laser
printers.
Page orientation is important when printing on letterhead. Use the following sections to determine which direction to
load the letterhead in each paper source:
Loading letterhead in the multipurpose feeder
Note:
Place the letterhead facedown in the multipurpose feeder with the long edge of the paper entering the printer
first.
