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 than 178 mm (7 in.). This may be caused by paper that has
been affected by environmental conditions. For optimum performance,
make sure you are storing and handling the paper correctly (see
Printing and Paper Storage Environment).
In the printer driver select Optimize for: and choose envelopes in the
drop-down box (see Optimizing for Media Types). For non-Windows
operating systems, this feature is also available in HP Web JetAdmin.
