Supported types of paper Use settings on the printer control panel to select the following types of paper and other print media. ● Plain ● Pre-printed ● Letterhead ● Transparency (see Transparencies) ● Prepunched ● Labels (see Labels) ● Bond ● Recycled ● Color ● Card stock (see Card stock and heavy paper) ● Rough ● Envelope (for Tray 1 only) Guidelines for using paper For best results, use conventional 75 g/m2 (20 lb) paper. Make sure the paper is of good quality, and free of cuts, nicks, tears, spots, loose particles, dust, wrinkles, voids, and curled or bent edges. If you are unsure what type of paper you are loading (such as bond or recycled), check the label on the package of paper. Some paper causes print quality problems, jamming, or damage to the printer. Do not use letterhead paper that is printed with low-temperature inks, such as those used in some types of thermography, and do not use raised letterhead. Coated papers and some transparencies can wrap around the fuser roller and possibly cause jams. The printer uses heat and pressure to fuse toner to the paper. Make sure that any colored paper or preprinted forms use inks that are compatible with the printer fusing temperature (392°F or 200°C for 0.1 second).
