  • Page 31: Black Page

    Black Page Black output is usually caused by an incorrect high voltage in the printing process, resulting in toner development on the entire photoconductor drum. Check the condition of each HVPS contact and make sure they spring back when pressed. Check the continuity of the HVPS cable.

  • Page 32: Blank Page

    Blank Page Inspect the printhead shutter for proper operation and make sure the actuator on top of the cartridge is present and extends into the printhead shroud when the printer top cover is closed. A failed printhead will cause a 931 Service error rather than blank output. Check the continuity of the HVPS cable.

Blurred or Fuzzy Print This can be caused by a damaged gear train or by paper slippage in the feed roll or transfer roll.

  • Page 34: Duplex

    If some voltages are present, but all are not correct, disconnect all cables except the LVPS from the system board. POR and verify that the LVPS voltages are correct. Turn the power back off and, one at a time, reconnect the system board cables, powering on in between each connection and checking the voltages.

  • Page 35: Fan (927 Error)

    sure the duplex table cover (floor) is correctly snapped in place at its front and rear and that the gear block assembly is correctly snapped into the bottom cover. Run duplex diagnostics tests #1 and #2 to make sure there is no slippage in the paper path. Make sure the flags of the duplex unit input and exit sensors move freely.

  • Page 36: Fuser Theory

    Fuser Theory The fuser lamp operates off line voltage from the LVPS. The thermistor is in contact with the fuser hot roll. The system board reads the thermistor resistance and toggles a TRIAC in the LVPS which cycles the lamp on and off to maintain the proper hot roll temperature.

  • Page 37: Fuser: 923 Error

    If the thermal fuse has blown, the fuser and the fuser wiper will be damaged. Before replacing the fuser and the fuser wiper, check the voltage at (10P) J11-16 (10R/12R/12C/12L) J11-3 (16L)J18-16 as you POR again. It should stay at 0 until the 922 Error is displayed and then go to +24VDC(10P: +5VDC);...
