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:
z Weight: See page 258
for supported envelope weight.
z 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.)
z Condition: Make sure envelopes are not wrinkled, nicked, or otherwise
damaged.
z Sizes in Tray 1: See page 256
for supported paper sizes.
z Sizes in the optional envelope feeder: From 3.5 by 6.3 inches (90 by 160
millimeters) to 7 by 10 inches (178 by 254 millimeters).
