When selectingenvelopes, consider the following factors:- Weight: The weight of the envelope papershould not exceed 90 g/m 2 or jamming mayoccur.- Construction: Prior to printing, envelopesshould lie flat with less than 6 mm curl, andshould 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 machine 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.AcceptableUnacceptable• Envelopes with a peel-off adhesive strip or withmore than one flap that folds over to seal mustuse adhesives compatible with the machine’sfusing temperature for 0.1 second. Check yourmachine’s specification to view the fusingtemperature, see page 10.1. The extra flaps andstrips might cause wrinkling, creasing, or jams,and may even damage the fuser.• For the best print quality, position margins nocloser than 15 mm from the edges of theenvelope.• Avoid printing over the area where theenvelope’s seams meet.Labels • To avoid damaging the machine, use only labelsdesigned for use in laser machines.• When selecting labels, consider the followingfactors:- Adhesives: The adhesive material should bestable at your machine’s fusing temperature.Check your machine’s specification to view thefusing temperature, see page 10.1.- Arrangement: Only use labels with noexposed backing between them. Labels canpeel off sheets that have spaces between thelabels, causing serious jams.- Curl: Prior to printing, labels must lie flat withno more than 13 mm of curl in any direction.- Condition: Do not use labels with wrinkles,bubbles, or other indications of separation.• Make sure that there is no exposed adhesivematerial between labels. Exposed areas cancause labels to peel off during printing, whichcan cause paper jams. Exposed adhesive canalso cause damage to machine components.• Do not run a sheet of labels through the machinemore than once. The adhesive backing isdesigned for only a single pass through themachine.• Do not use labels that are separating from thebacking sheet or are wrinkled, bubbled, orotherwise damaged.Card stock orcustom-sizedmaterials• Do not print on media smaller than 76 mm wideor 356 mm long.• In the software application, set margins at least6.4 mm away from the edges of the material.Media type Guidelines
