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
2
) may cause
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
those that interlock should not be used.
