Envelopes with double side seams
Double side-seam construction has vertical seams at both ends of the envelope rather than
diagonal seams. This style might 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 even jams and might even damage the fuser.

NOTE
For the best print quality, position margins no closer than 15 mm (0.6 inch) from the edges
of the envelope. Avoid printing over the area where the envelope's seams meet.
Envelope storage
Proper storage of envelopes helps contribute to print quality. Envelopes should be stored
flat. If air is trapped in an envelope, creating an air bubble, then the envelope might wrinkle
during printing.
