Lexmark W850 Minimizing your printer's environmental impact

Minimizing your printer's environmental impact

Lexmark is committed to environmental sustainability and is continually improving its printers to reduce their impac t

on the environment. We design with the environment in mind, engineer our packaging to reduce materials, and provide

collection and recycling programs. For more information, see:

•The Environmental Sustainability section of the Lexmark Web sit e at www.lexmark.com/environment

•The Lexmark recycling program at www.lexmark.com/recycling

By selecting certain printer settings or tasks, you may be able to reduce your print er's impact even further. This chapter

outlines the settings and tasks that may yield a greater environmental benefit.

As an environmentally conscious company, Lexmark su pports the use of recycled office paper produced specifically for

use in laser (electrophotographic) printers. In 1998 , Lexmark presented to the US government a study demonstratin g

that recycled paper produced by major mills in the US fed as well as non-recycle d 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-co nsumer waste) and a variety of test paper

from around the world, using chamber tests for different temperature and humidit y conditions. Lexmark has found no

reason to discourage the use of today's recycled office pap ers, but generally the following property guidelines apply

to recycled paper.

•Low moisture content (4–5%)

•Suitable smoothness (100–200 Sheffield units, or 14 0–350 Bendtsen units, European)

Note: Some much smoother papers (such as premium 24 lb laser papers, 50–90 Sheffiel d units) and much

rougher papers (such as premium cotton papers, 200–3 00 Sheffield units) have been engineered to work very

well in laser printers, despite surface texture. Before us ing 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/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) f ed printers may have lower bending resistance than is re quired for

reliable paper feeding. Before using these types of paper for laser (electrophotographic) printing, consult your p aper

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, i f the paper curls excessively under normal printing

conditions).

Available settings range from 2–240 minutes. The factory default setting is 10 minutes.
