Guidelines for using media Note Use the information in this section to choose the proper print media. Paper and transparencies Paper must be of good quality and free of cuts, nicks, tears, spots, loose particles, dust, wrinkles, holes, and curled or bent edges. Check the label on the paper package for details about the type of paper (such as bond or recycled). Some paper causes print-quality problems, jamming, or damage to the printer. Do not use letterhead that is printed with low-temperature inks, such as those used in some types of thermography; raised letterhead; or colored paper or preprinted forms that use inks incompatible with the printer temperature (200° C, or 392° F, for 0.1 second). Transparencies must be able to withstand 200° C (392° F), the printer's maximum temperature. Common media problems Table 2-3. Common media problems Symptom Problem with paper Solution Poor print quality or problems with feeding. Too moist, too rough, too smooth, or embossed. Faulty lot. Try another kind of paper between 100 and 250 Sheffield. Use a fresh ream of paper to ensure proper moisture content. Poor toner adhesion Too smooth. Try another kind of paper between 100 and 250 Sheffield. Make sure the proper paper type is selected, so the fuser is set for the proper mode. Dropouts, jamming, or curl. Stored improperly. Store paper flat in its moisture-proof wrapping. Gray area along the edge of the page. Media might be too heavy. Use a lighter-weight media. Increased gray background shading. Might be too dark, or you are using recycled paper. Use whiter-colored media. Reduce the contrast by pressing the LIGHTER/DARKER button on the control panel. Excessive curl, or problems with feeding. Too moist, wrong grain direction, or short-grain construction. Use long-grain paper. Print using the straight-through output path. For copy or fax jobs, select less paper curl in the service menu. For print jobs, select a lighter-weight media type from the printer driver or the HP Toolbox. 36 Chapter 2 Operation ENWW
