Notes
• Avoid using self-adhesive envelopes. They may cause machine malfunctions.
• The number of envelopes that can be printed per minute is approximately half that of middle thick
paper.
• Paper can be loaded only up to the lower of the two paper limit marks of the tray.
• If printed envelopes come out badly creased, load the envelopes in the opposite direction. Also,
configure the printer driver to rotate the print object 180 degrees. For details about changing the
orientation see the printer driver Help.
• Environmental factors can degrade the print quality on both recommended and non-recommended
envelopes.
• If envelopes are severely curled after printing, flatten them by bending them back against the curl.
• After printing, envelopes sometimes have creases along their long edges and toner smear on their
unprinted sides. Print images might also be blurred. When printing large, black-solid areas, striping
can occur as a result of the envelopes overlapping.
• To correctly specify the length of an envelope whose flap opens along its short edge, be sure to
include the open flap when measuring.

• Fan envelopes, and then align their edges before loading.
