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:


The weight of the envelope paper should not exceed

28 lb (105 g/m


), or jamming may result.


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.)


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) 12.28 by 18.5 inches (312 by 470 mm).

Always print envelopes from Tray 1 (page 29). To prevent envelopes
from wrinkling or jamming, open the rear output bin.

Envelopes with Double-Side-Seams

Double-side-seam construction has vertical seams at both ends of
the envelope rather than diagonal seams. This style may be more
likely to wrinkle. Be sure the seam extends all the way to the corner
of the envelope as illustrated below.

Envelopes with Adhesive Strips or Flaps

Envelopes with a peel-off adhesive strip or with more than one flap
that folds over to seal must use adhesives compatible with the heat
and pressure in the printer. The extra flaps and strips might cause
wrinkling, creasing, or jams.

Envelope Margins

The following table gives typical address margins for a Commercial
#10 or DL envelope.


For the best print quality, position margins no closer than 0.6 inch
(15 millimeters) from the edges of the envelope.

Envelope Storage

Proper storage of envelopes helps contribute to good print quality.
Envelopes should be stored flat. If air is trapped in an envelope,
creating an air bubble, then the envelope may wrinkle during
