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 the Menus 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.
