    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, Table 7. Determining Basis Weight Of Paper

    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: Table 8. Paper Weight Equivalence

    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: Figure 10. Long, Short, And Diagonal Grain Curl

    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 will compress the paper fibers, resulting in an inaccurate reading.

  • Page 40: Figure 11. Measuring Curl

    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 users contact the forms vendor to ensure paper fusing compatibility with HP LaserJet printers. 38 Chapter 2 Product requirements...

    Optional tray 1 The optional tray 1 is a multipurpose tray that picks up and feeds media into the printer. Tray 1 driver PCB A driver PCB in the tray holds a four-bit microcomputer (CPU-IC2501) that controls its operational sequence and serial communications with the DC controller PCB. The CPU drives a motor, solenoid, and clutch according to commands sent from the DC controller PCB.

  • Page 105: Pickup And Feed, Jam Detection

    Pickup and feed The tray 1 pickup unit picks up paper by bringing down the pickup roller onto the surface of the paper loaded in the tray and separating the roller from the paper surface. The pickup roller is lifted up and down by the pickup cam. When the tray 1 pickup unit turns on the pickup solenoid, the stopper leaves from the cam, allowing the cam to rotate.

  • Page 106: Optional Tray 4, Tray 4 Driver Pcb, Power Supply, Sequence Of Operation

    Optional tray 4 The optional tray 4 is a 2000-sheet feeder that picks up and feeds media into the printer. Tray 4 driver PCB A driver PCB in the tray holds a 16-bit microcomputer (IC1) that controls its operational sequence and serial communications with the formatter.

  • Page 107: Media Level And Size Detection, Pickup And Feed, Jam Detection

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

  • Page 108: Optional 3000-sheet Stapler/stacker, Controller Pcb, Power Supply, Power-on Sequence

    Optional 3000-sheet stapler/stacker The 3000-sheet stapler/stacker is a multi-speed output device. It staples up to 50 sheets of plain paper at a time and can hold a total of 3125 sheets—3000 sheets in the stapler bin and 125 sheets, not stapled, in the face-up bin. Controller PCB Communication and control of the 3000-sheet stapler/stacker is accomplished through the paper- handling controller embedded on the formatter in the printer.

  • Page 109: Main Modules, Figure 44. Stapler/stacker Main Modules

    Main modules The 3000-sheet stapler/stacker is made up of the following main modules: Face-up bin—This bin will collect the documents face up, with the printed information toward the user. Finished documents are not routed to this bin, yet the bin does give support to sheets being flipped to the face-down bin.

  • Page 110: Paper Path And Jam Detection, Figure 45. Stapler/stacker Jam Detection

    Paper path and jam detection Paper input—The device receives paper from the HP LaserJet 9000 Series printer at 230 mm per second. Flipper—Paper arrival is sensed by FLEntry1, which activates the flipper motors. For face-up printing, the flipper delivers the paper sensed by FLEntry to the face-up bin. Otherwise, the flipper changes page orientation from face-up to face-down and delivers paper sensed by FLExit to the paper path module.
