Envelopes
Envelope construction is critical. Envelope fold lines can vary
considerably, not only between manufacturers, but also within a box
from the same manufacturer. Successful printing on envelopes
depends upon the quality of the envelopes. When selecting
envelopes, consider the following components:
z Weight: The weight of the envelope paper should not exceed
105 g/m
2
(24 lb) or jamming may occur.
z Construction: Prior to printing, envelopes should lie flat with less
than 6 mm (0.25 in.) curl, and should not contain air.
z Condition: Envelopes should not be wrinkled, nicked, or
otherwise damaged.
z Temperature: You should use envelopes that are compatible with
the heat and pressure of the printer.
z Size: You should use only envelopes within the following size
ranges.
Note Use only Tray 1 to print envelopes.
You may experience some paper jams when using any media with a
length less 178 mm (7 in.). This may be caused by paper that has been
effected by environmental conditions. For optimum performance, make
sure you are storing and handling the paper correctly. Please refer to
“Printing and Paper Storage Environment” on page 144.
