Envelopes
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: The weight of the envelope paper should not exceed
28 lb (105 g/m
2
), or jamming may result.
•
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: From 3 by 5 inches (76 by 127 mm) to 8.5 by
14 inches (216 by 356 mm).
•
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).
If you do not have an optional envelope feeder, always print
envelopes from Tray 1 (page 47). To print envelopes with the
optional envelope feeder, see page 49. If envelopes wrinkle, try
opening the rear output bin.
