  • Description: Shading trouble (Black correction)
    The CCD black scan level is abnormal when the shading.
  • Causes: Improper connection of the CCD unit flat cable CCD unit abnormality MCU PWB abnormality
  • Remedy: Check connection of the CCD unit flat cable. Check the CCD unit.
  • Code: E7-11
  • Description: Shading trouble (White correction)
    The CCD white scan level is abnormal when the shading.
  • Causes: Improper connection of the CCD unit flat cable Dirt on the mirror, the lens, and the reference white plate Copy lamp lighting abnormality CCD unit abnormality MCU PWB abnormality (When occurred in the SPF scan position.) Improper installation of the mirror unit
  • Remedy: Clean the mirror, lens, and the reference white plate. Check the light quantity and lighting status of the copy lamp (TC 05-03). Check the MCU PWB.
  • Code: E7-16
  • Description: Abnormal laser output
    When the laser output is stopped, HSYNC is detected.
  • Causes: Laser abnormality MCU PWB abnormality.
  • Remedy: Check the laser emitting diode operation. Replace the MCU PWB.
  • Code: F2-04
  • Description: Improper cartridge (Destination error, life cycle error)
    The destination of the main unit differs from that of the CRUM. The life cycle information is other than "FFh" (Not used).
  • Causes: CRUM chip trouble Improper developing unit
  • Remedy: Replace the CRUM chip. Replace the developing unit.
  • Code: F5-02
  • Description: Copy lamp lighting abnormality
    The copy lamp does not turn on.
  • Causes: Copy lamp abnormality Copy lamp harness abnormality CCD PWB harness abnormality.
  • Remedy: Use TC 5-3 to check the copy lamp operations. When the copy lamp lights up. Check the harness and the connector between the CCD unit and the MCU PWB. When the copy lamp does not light up. Check the harness and the connector between the copy lamp unit and the MCU PWB. Replace the copy lamp unit. Replace the MCU PWB.
  • Code: F6-10
  • Description: FAX board trouble
    Communication trouble between MCU and FAX control PWB
  • Causes: FAX control PWB connector disconnection Defective harness between FAX control PWB and MCU PWB Motherboard connector pin breakage FAX control PWB ROM error/Data error IC on FAX PWB causes abnormality
  • Remedy: Check connector/harness of FAX control PWB and MCU PWB. Check the grounding of the copier. Check FAX control PWB ROM. Replace the FAX PWB.
  • Code: H2-00
  • Description: Thermistor open
    The thermistor is open. The fusing unit is not installed.
  • Causes: Thermistor abnormality Control PWB abnormality Fusing section connector disconnection The fusing unit is not installed.
  • Remedy: Check the harness and the connector between the thermistor and the PWB. Use TC 14 to clear the self diagnostic display.
  • Code: H3-00
  • Description: Heat roller high temperature detection
    The fusing temperature exceeds 240°C.
  • Causes: Thermistor abnormality Control PWB abnormality Fusing section connector disconnection.
  • Remedy: Use TC 5-02 to check the heater lamp blinking operation. When the lamp blinks normally. Check the thermistor and its harness. Check the thermistor input circuit on the control PWB. When the lamp keeps ON. Check the power PWB and the lamp control circuit on the MCU PWB. Use TC 14 to clear the self diagnostic display.
