NOTE Media Selection Guidelines More detailed specifications are in the HP LaserJet Printer Family Paper Specification Guide, HP Part No. 5002-1801 (See "Related Documentation and Training Media" later in this chapter). CAUTION Paper To achieve the best possible print quality and avoid paper jams, follow these guidelines for selecting paper: • Use only copier grade paper that meets all specifications in the paper specification guide. Avoid paper with embossed lettering, perforations, or texture that is too smooth or too rough. • Colored paper should be of the same high quality as white photocopy paper. The pigments must withstand the fusing temperature of 392° F (200° C) for 0.1 second without deterioration. Do not use paper with a colored coating that was added after the paper was produced. • Pre-printed forms must be printed with non-flammable, heat-resistant inks that do not melt, vaporize, or release hazardous emissions when subjected to the fusing temperature of 392° F (200° C) for 0.1 second. • A small sample of a new print media should be tested before purchasing large quantities. Envelopes To prevent severe printer damage, do not use envelopes having windows, clasps, snaps, or synthetic materials. Envelopes can be printed only from the MP Tray. Choose envelopes that are well-constructed. They should lay flat and be sharply creased. They should not be wrinkled, nicked, or otherwise damaged. Envelope adhesive must be compatible with the heat and pressure of the fusing process. 1-8 Product Information
