• When selecting envelopes, consider the following factors:
- Weight: should not exceed 90 g/m
2
otherwise; jams may
occur.
- Construction: should lie flat with less than 6 mm curl and
should not contain air.
- Condition: should not be wrinkled, nicked, nor damaged.
- Temperature: should resist the heat and pressure of the
machine during operation.
• Use only well-constructed envelopes with sharp and well-
creased folds.
• Do not use stamped envelopes.
• Do not use envelopes with clasps, snaps, windows, coated lining,
self-adhesive seals, or other synthetic materials.
• Do not use damaged or poorly made envelopes.
• Be sure the seam at both ends of the envelope extends all the
way to the corner of the envelope.

• Envelopes with a peel-off adhesive strip or with more than one
flap that folds over to seal must use adhesives compatible with
the machine’s fusing temperature for 0.1 second (about 170°C
(338 °F)). The extra flaps 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
from the edges of the envelope.
• Avoid printing over the area where the envelope’s seams meet.
