Understanding print media guidelines

Condition paper while it is still in the original wrapper. To condition it, store it in the same environment as the printer for 24 to 48 hours before printing to let the paper stabilize in the new conditions. Extend the time several days if the storage or transportation environment is very different from the printer environment. Thick paper may also require a longer conditioning period because of the mass of material.

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 to 90 g/m2 (16 to 24 lb bond) paper, grain long fibers are recommended.

Fiber content

Most high-quality xerographic paper is made from 100% chemically 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 possess characteristics that can result in degraded paper handling.

Recycled paper

Lexmark supports US executive order 13101 which strongly encourages the use of recycled papers in government agencies. Ask for warranty information and performance claims from your paper supplier, and/or test small quantities before buying large amounts. A list of suppliers and approved papers used by the US Government Printing Office can be found at http://www.gpo.gov/qualitycontrol/cpypaper.htm.

Unacceptable paper

The following papers are not recommended for use with the printer:

•Chemically treated papers used to make copies without carbon paper, also known as carbonless papers, carbonless copy paper (CCP), or no carbon required (NCR) paper

•Preprinted papers with chemicals that may contaminate the printer

•Preprinted papers that can be affected by the temperature in the printer fuser

•Preprinted papers that require a registration (the precise print location on the page) greater than ±0.09 in., such as optical character recognition (OCR) forms

In some cases, you can adjust registration with your software application to successfully print on these forms.

•Coated papers (erasable bond), synthetic papers, thermal papers

•Rough-edged, rough or heavily textured surface papers or curled papers

•Recycled papers containing more than 25% post-consumer waste that do not meet DIN 19 309

•Recycled paper having a weight less than 60 g/m2 (16 lb)

•Multiple-part forms or documents

Selecting paper

Proper paper loading helps prevent jams and ensures trouble-free printing.

To help avoid jams or poor print quality:

•Always use new, undamaged paper.

•Before loading paper, know the recommended print 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 media sizes, weights, or types in the same source; mixing results in jams.

•Do not use coated papers unless they are specifically designed for electrophotographic printing.

•Do not remove trays while a job is printing or Busy appears on the control panel.
