User’s Manual3-23PRINTING ANDPAPER HANDLINGHandling Paper• Use materials specially designed for laser printers or photocopiers.• Always feed transparency material from the manual feed slot or theoptional multi-function feeder.• To remove curls from printed transparency materials, use correct framesor put a weight on them until they lay flat.• Be sure to fan the transparency stack to prevent sheets from stickingtogether.EnvelopesThis printer prints well on envelopes if you carefully follow theseguidelines:• Use envelopes made of paper in 75 to 105 g/m2 (20 to 28 pound)weight. Printing with envelopes made of paper thinner than this weightmay produce wrincles thus causing decrease in print quality.• Be sure to set up the rear stacker so that envelopes are ejected straightout the back to minimize curl.The capacity of the rear stacker is about 20 sheets.• Use the envelope sizes shown in the preceding table.• To avoid damage to the printer, never use envelopes with clasps, snaps,windows, or synthetic materials.• Feed from the manual feed slot or the optional multi-function feeder.• Feed the envelopes with the gummed side of the flaps facing downward.• Do not use “encapsulated” adhesives, which seal by pressure alone.• To avoid jamming, restrict the minimum paper weight to 64 g/m2 (17pound).• To avoid creasing along the edges, use high-quality envelopes with stiffedges.• To avoid uneven printing, do not attempt to print on the gummedoverlap areas.• Be sure to feed or load the envelopes with the envelope centered againstthe manual feed slot. Use the guide of the paper sizes.• Before attempting large-scale printing on envelopes, consult with yourstationery dealer. Also, test the envelopes carefully for consistent,trouble-free printing.
