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 that are compatible with the heat and pressure in the printer.
CAUTION The extra flaps and strips might cause wrinkling, creasing, or jams, and can even damage the
fuser and separation pad.
Envelope storage
Proper storage of envelopes contributes to good print quality. Envelopes should be stored flat. If
air is trapped in an envelope and creates an air bubble, then the envelope might wrinkle during
printing.
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 that the seam extends all the
way to the corner of the envelope, as illustrated.

Envelope margins
The following gives typical address margins for a commercial #10 or DL envelope.
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 seams meet.
