Media specifications

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, registration can be adjusted with the 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

•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 forget to change the Paper Size setting when using a source that does not support auto size sensing.

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

•Make sure the Paper Type and Paper Weight settings are correct. (See “Paper Menu” in theMenus and Messages Guide on the publications CD for detailed information about these settings.)

•Make sure the paper is properly loaded in the source.

•Flex paper back and forth. Do not fold or crease the paper. Straighten the edges on a level surface.

Storing paper

Use the following guidelines to avoid paper feeding problems and uneven print quality.

•Store paper in an environment where the temperature is approximately 21°C (70°F) and the relative humidity is 40%.

•Store cartons of paper on a pallet or shelf rather than directly on the floor.
