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 may even damage the fuser.
