Transparencies Printing on transparencies presents a special set of challenges. The surface resistance of a transparency can be infinite, causing the transparency to act like paper with 0% moisture content. This may resulting in streaks and smudging. Static charges may accumulate on some transparent stock and cause multifeed jams. Also, certain brands and types of transparencies will not tolerate exposure to the fuser. The user should only select transparencies that meet HP specifications. Among the common precautions are: • Print transparencies to the top output bin to avoid jams. • Transparencies must have correct resistivity (not build up static charge). See "Transparency Specifications" (page 36). • Transparencies must meet HP specifications for fusing compatibility. • Each sheet should be removed from the tray and placed on a flat surface before printing the next sheet. This will keep the toner form rubbing off onto the next sheet before it has had time to cool. Chemically Treated Paper Coatings such as lacquers, polymers, laminations, or other chemicals protect the paper but can cause problems in the fuser and transfer areas of HP LaserJet printers. The surface resistivity and moisture content can be greatly altered, resulting in print quality problems. Hard surface coatings increase wear on the rollers and paper guides. All chemically treated paper must meet HP specifications for fusing compatibility. Synthetic Paper Synthetic papers (those manufactured from man-made fibers) do not perform as well as bond papers in any printer, especially HP LaserJet printer. All synthetic papers must meet HP specifications, especially for caliper and fusing compatibility. See "General Media Specifications" (page 28). C4170-90959 Media Troubleshooting 135
