● Envelopes with a peel-o adhesive strip or with more than one ap that folds over to seal must use
adhesives compatible with the printer’s fusing temperature of about 170°C (338 °F) for 0.1 second. The
extra aps and strips might cause wrinkling, creasing, or jams, and may even damage the fuser.
● For the best print quality, position margins no closer than 15 mm (0.6 inches) from the edges of the
envelope.
● Avoid printing over the area where the envelope’s seams meet.
