    C3166-69010 (Exchange), RG5-1844-050CN (New) Situation: HP has been investigating an increase in calls regarding toner dumping inside of the printer. The investigation revealed three potential scenarios in which toner dumps. It is imperative that the support partners thoroughly troubleshoot this condition in order to successfully complete the repair.

  • Page 222

    Scenario Number 3: (Least likely scenario) The printer may be exhibiting a 79 Service (04CC) error. The 79 Service (04CC) was added to the firmware code of formatters (9.1 version or greater) to capture the signal combination that resulted in toner dumping. Verify that the DC controller is not a 1.11 version, as in scenario number 2.

    • FORM LENGTH SELECTION FROM THE FRONT PANEL. This function can be found in the PCL MENU structure of the control panel. • SLOW PRINTING OF FORMS. Versions 7.9, 8.5, and 8.6 firmware had a problem handling raster graphics in 300 dot-per-inch (dpi) mode.

  • Page 226

    Situation: The LaserJet 5Si printer was introduced without the capacity of being able to set a default front panel font. HP soon realized the importance of this capability to many customers, particularly those in a UNIX environment who rely on setting a default font at the front panel of the printer.

  • Page 227

    Action: Replace the formatter assembly according the instructions provided in the removal and replacement section of the service manual, part number C4077-99014. BE SURE TO RE-ENTER THE SERIAL NUMBER, PAGE COUNT, AND MAINTENANCE COUNT VIA THE SERVICE MODE. This information is required so the printer will report the “PERFORM USER MAINTENANCE”...

    Compressed Print Associated Part Numbers: RG1-1777-000CN - drum drive gear assembly Description: On rare occasions, you may see compressed print on a LaserJet IIP. The print may be compressed anywhere on the page. It may look like text compressed into a thin line or appear as a gap between lines.

  • Page 264

    Why does this happen? When something causes the toner cartridge to freeze up, the shaft on the drum drive gear continues to turn for a short period of time but the gear does not. This can later cause the toner cartridge drum to stop turning momentarily due to slippage between the deformed gear and the shaft (even though the rest of the printer is functioning normally).

  • Page 265

    Description: On rare occasion, when using the HP PostScript Cartridge (HP 33439P/Q) with a LaserJet IIP, a continuous PS BUSY condition can occur if auto continue is ON and the document being printed is longer than 1 or 2 pages. If the page is printed, this condition may result in missing lines, shifted text, and some malformed letters.

  • Page 266
