Paper Type and Quality
The cut sheet feeder requires plain bond, typewriter, or xerographic quality paper with a minimum of
wood pulp.
Cut sheet paper and envelopes must be in as a good condition as new: must be flat, not be curled or
curved, and must be without damage at the surface or the edges. Additionally, envelopes must be well
creased.
NOTES: 1. All other paper with medium or high wood content and very light or very heavy paper must
be operationally tested prior to regular use.
Paper with a textured, embossed, glossy, or hammered surface also must be tested
individually prior to regular use.
2. The cut sheet feeder may not feed smoothly with some kinds of paper.
3. Using curled or curved paper causes the paper to jam. Therefore, paper should always be
removed from the platen when the printer is not in use.
