    Preprinted forms and special letterhead Many preprinted forms and special letterhead papers perform well in HP LaserJet printers. However, these papers undergo processes that alter their original characteristics, and care must be taken to ensure they conform to HP specifications. All special papers should be wrapped in moisture-proof wrapping when purchased from the paper converter or printing house.

  • Page 36: Storing Print Media

    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 media guides.

  • Page 37: Testing Media Specifications

    The following tests describe ways to evaluate media with respect to the specifications listed in this manual, and the HP LaserJet Printer Family Print Media Guide. See "Tools and suppliers" on page 39 for help obtaining tools needed to perform these tests.

  • Page 38

    Metric sizes For metric-size paper (A4), use the following method to determine basis weight. Take 16 sheets of A4 paper and weigh them. One square meter of paper contains approximately 16 A4 size sheets. Compare this weight to the appropriate weight in the "Paper weight equivalence table"...

  • Page 39

    Caliper field test The specified caliper differs according to the type of media used. See "Media specifications" on page 31. Caliper can be measured in the field using a micrometer. CAUTION Never use the coarse adjustment end of the micrometer when measuring for caliper. The coarse adjustment compresses the paper fibers, resulting in an inaccurate reading.

  • Page 40

    Inspect the rollers for colored ink buildup from preprinted logos or letterhead, and for toner buildup or spots. Inspect printed output for repetitive defects and smearing. If necessary, have customers contact the forms vendor to ensure fusing compatibility with HP LaserJet printers. 38 Chapter 2 Product requirements...

    Pickup and feed The formatter sends a signal to the driver PCA to start driving the pickup and feed motors. Rotated by the rollers, the pickup roller picks up a sheet, the separation roller removes any excessive sheets, and the feed roller transports the sheet to the registration roller unit. After the media enters the registration roller unit, the registration roller corrects the skew and the second feed roller feeds the media to the printer.
