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 37).
• 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 printers. All synthetic papers must meet
HP specifications, especially for caliper and fusing compatibility. See “General Media
Specifications” (page 28).
