Menu Overview and Basic Setup- Temperature: should resist the heat and pressure of the machineduring 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 thecorner of the envelope.1 Acceptable2 Unacceptable• Envelopes with a peel-off adhesive strip or with more than one flap thatfolds over to seal must use adhesives compatible with the machine’s fusingtemperature for 0.1 second about 170°C (338 °F). The extra flaps and stripsmight cause wrinkling, creasing, or jams, and may even damage the fuserunit.• For the best print quality, position margins no closer than 15 mm from theedges of the envelope.• Avoid printing over the area where the envelope’s seams meet.TransparencyTo avoid damaging the machine, use only transparencies designed for use inlaser printers.• Must withstand the machine’s fusing temperature.• Place them on a flat surface after removing them from the machine.• Do not leave unused transparencies in the paper tray for long. Dust and dirtmay accumulate on them, resulting in spotty printing.• To avoid smudging caused by fingerprints, handle them carefully.• To avoid fading, do not expose printed transparencies to prolongedsunlight.• Ensure that transparencies are not wrinkled, curled, or have any torn edges.
