Envelope Construction
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:
! Weight: See page 395
for supported envelope weight.
! Construction: Prior to printing, envelopes should lie flat with less than
0.25 inch (6 mm) curl and should not contain air. (Envelopes that trap air
may cause problems.)
! Condition: Make sure envelopes are not wrinkled, nicked, or otherwise
damaged.
! Sizes in Tray 1: See page 392
for supported paper sizes.
! Sizes in the optional envelope feeder: See page 395
for supported envelope
sizes.
