Make sure the envelopes installed in the tray meet
specifications.
Some guidelines that can be used in selection of
envelopes that will minimize the jam rate are:
• Flat envelopes that are not warped or twisted.
• Flexible envelopes that can conform to the paper
path.
• Smooth surface on the envelopes. Rough or ridged
surfaces may cause the envelopes to stick together
in the tray.
• No cotton content, or as little as possible to meet
the user’s needs.
• If the envelopes have a pressure-sensitive
adhesive flap, performance might be improved by
reversing the orientation of the envelope in the tray
and reversing the image in the drive or application.
Are any problems found with the envelopes?
Inform the
customer of the
problems with the
envelopes that
do not meet
specifications.
