Media guidelines

Paper
Following are media guidelines for successful printing:
Rough, highly textured, limp or pre-curled papers will result in
lower print quality and more frequent paper feed failures.
Colored papers, treated and preprinted papers, letterhead and
labels must be able to withstand 338° F (170° C) fusing
temperature.
Preprinted forms and letterhead should be selected using
guidelines found in the printer User's Guide. The chemical
process used in preprinting may render some papers
unsuitable.
Unsuitable papers include multipart forms and documents;
chemically treated papers; coated, synthetic, and thermal
papers; and preprinted papers requiring a high degree of
registration.
Recycled paper less than 21 lb (80 g/m
unacceptable results.
Envelopes
Envelopes should be fed long edge first, with flap trailing.
When the finisher is attached, only long-edge fed envelopes
wider than 5.8 in. (148 mm) feed direction dimension may be
used. To print smaller envelopes, the finisher must be undocked
during the job.
If envelope wrinkling occurs, refer to the User's Guide for correct
weight, type, loading and stacking of envelopes.
All envelopes should be new, unused and without package
damage.
Envelopes with excessive curl or twist exceeding 0.12 in.
(6 mm), stuck together, with bent corners or nicked edges or
