Note Guidelines for using paper For best results, use conventional 75 to 90 g/m2 (20 to 24 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 product. Symptom Poor print quality or toner adhesion. Dropouts, jamming, curl. Problem with paper Too moist, too rough, too smooth, or embossed. Ragged edges. Faulty paper lot. Stored improperly. Increased gray background shading. Too heavy. Too smooth. Excessive curl. Problems with feeding. Too moist, wrong grain direction, or short-grain construction. Solution Try another kind of paper, between 100 to 250 Sheffield, 4 to 6 percent moisture content. Store paper flat in its moisture-proof wrapping. Use lighter paper. Open the rear output slot. Use less smooth paper. Open the rear output slot. Use long-grain paper. Store paper in a drier environment. Do not use letterhead paper that is printed with low-temperature inks, such as those used in some types of thermography. Do not use raised letterhead. The product 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 product's temperature of 230° C (446° F) for 0.05 second. Avoid using paper that has been damaged by having already been used in a printer or copier. (Do not print on both sides of envelopes, transparencies, or labels.) 118 Appendix A - Specifications EN
