1 Pressure leverMedia and tray_ 29• When selecting envelopes, consider the following factors:- Weight: The weight of the envelope paper should not exceed90 g/m2 otherwise, jam may occur.- Construction: Prior to printing, envelopes should lie flat with lessthan 6 mm curl, and should not contain air.- Condition: Envelopes should not be wrinkled, nicked, nordamaged.- Temperature: Use envelopes that are compatible with the heat andpressure 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 tothe corner 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’sfusing temperature (about 170°C(338 °F)) for 0.1 second. The extraflaps and strips might cause wrinkling, creasing, or jams, and may evendamage the fuser.• For the best print quality, position margins no closer than 15 mm fromthe edges of the envelope.• Avoid printing over the area where the envelope’s seams meet.TransparencyTo avoid damaging the machine, use only transparencies designed for usein laser printers.In case of color printing using transparencies, the picture quality wouldbe lower than mono printing when the printouts are used on theoverhead projector.• Transparencies used in the machine must be able to withstandmachine’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 periods oftime. Dust and dirt may 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 tornedges.• Do not use transparencies that separates from the backing sheet.• To prevent transparencies from sticking to each other, do not let theprinted sheets stack up as they are begin printed out.LabelsTo avoid damaging the machine, use only labels designed for use in lasermachines.• When selecting labels, consider the following factors:- Adhesives: The adhesive material should be stable at yourmachine’s fusing temperature (about 170°C(338 °F)).- Arrangement: Only use labels with no exposed backing betweenthem. Labels can peel off sheets that have spaces between thelabels, causing serious jams.- Curl: Prior to printing, labels must lie flat with no more than 13 mmof curl in any direction.- Condition: Do not use labels with wrinkles, bubbles, or otherindications of separation.• Make sure that there is no exposed adhesive material between labels.Exposed areas can cause labels to peel off during printing, which cancause paper jams. Exposed adhesive can also cause damage tomachine components.• Do not run a sheet of labels through the machine more than once. Theadhesive backing is designed for only a single pass through themachine.• Do not use labels that are separating from the backing sheet or arewrinkled, bubbled, or otherwise damaged.
