Minimizing your printer's environmentalimpact
Lexmark is committed to environ mental sustainabili ty and is conti nually improving it s printers to red uce their impact
on the environment. We design with the environment in mind, engineer our packaging to reduce materials, and
provide collection and recycling program s. For more information, see:
•The Notices chapter
•The Environmental Sustainability section of the Lexmark Web site at www.lexmark.com/ environment
•The Lexmark recycling program at www.lexmark.com/recycle
By selecting certain printer settings or tasks, you may be able to reduce your printer's impact even further. This chapter
outlines the settings and tasks that may yield a greater environmental benefit.

Saving paper and toner

Using recycled paper and other office papers

As an environmentally conscious company, Lexmar k supports the use of recycled office pape r produced specifically
for use in laser (electrophotographic) printers. In 1998, Lexmark presented to the US govern ment 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 of fice 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: Som e m u c h s m o o t he r p a p e r s ( s u c h a s p re m i u m 24 l b l a s e r pa p e r s , 50 – 9 0 S h e ff i e l d u n it s ) a n d m uc h r o u g h er
papers (such as premium cotton papers, 200–300 Sheffield u nits) have been engineered to work very well in
laser printers, despite surface texture. Before using t hese types of paper, consult your paper su pplier.
•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/m2 [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 o f paper for laser (electrophotograp hic) printing, consult your pap er
supplier. Remember that these are general guidelines only and that pa per meeting these guidelines may still cause
paper feeding problems in any laser print er (for example, if the paper curls exces sively under normal printing
conditions).

Conserving supplies
