When selectingenvelopes, consider the following factors:- Weight: The weight of the envelope papershould not exceed 90 g/m2 (24 lb) or jammingmay occur.- Construction: Prior to printing, envelopesshould lie flat with less than 6 mm(0.25 inches) curl, and should not contain air.- Condition: Envelopes should not be wrinkled,nicked, or otherwise damaged.- Temperature: You should use envelopes thatare compatible with the heat and pressure ofthe printer during operation.• Use only well-constructed envelopes with sharpand well creased folds.• Do not use stamped envelopes.• Do not use envelopes with clasps, snaps,windows, coated lining, self-adhesive seals, orother synthetic materials.• Do not use damaged or poorly made envelopes.• Be sure the seam at both ends of the envelopeextends all the way to the corner of theenvelope.• Envelopes with a peel-off adhesive strip or withmore than one flap that folds over to seal mustuse adhesives compatible with the printer’sfusing temperature of 200° C (392° F) for0.1 second. The extra flaps and strips mightcause wrinkling, creasing, or jams, and mayeven damage the fuser.• For the best print quality, position margins nocloser than 15 mm (0.6 inches) from the edgesof the envelope.• Avoid printing over the area where theenvelope’s seams meet.AcceptableUnacceptable
