Error Codes List page 4

  • Code: L3-00
  • Description: Scanner return trouble
    When the mirror base is returned for the specified time (6 sec) in mirror initializing after turning on the power, the mirror home position sensor (MHPS) does not turn ON. Or when the mirror base is returned for the specified time (about 6 sec) after start of copy return, the mirror home position sensor (MHPS) does not turn ON.
  • Causes: Mirror unit abnormality Scanner wire disconnection Origin detection sensor abnormality Mirror motor harness abnormality
  • Remedy: Use TC 1-1 to check the mirror reciprocating operations. When the mirror does not return. Check for disconnection of the scanner wire. Check the harness and the connector between the mirror motor and the MCU PWB. Replace the mirror unit. Replace the MCU PWB. When the mirror does feed. Use TC 1-2 to check the mirror home position sensor.
  • Code: L4-01
  • Description: Main motor lock detection
    When the main motor encoder pulse is not detected for 100 msec.
  • Causes: Main motor unit abnormality Improper connection or disconnection the main motor and the harness. MCU PWB abnormality
  • Remedy: Use TC 25-01 to check the main motor operations. Check connection of the main motor harness/ connector. Replace the main motor. Replace the MCU PWB.
  • Code: L6-10
  • Description: Polygon motor lock detection
    The lock signal (specified rpm signal) does not return within a certain time (about 20 sec) from starting the polygon motor rotation.
  • Causes: Polygon motor unit abnormality Improper connection or disconnection of the polygon motor and the harness. MCU PWB abnormality
  • Remedy: Use TC 61-1 to check the polygon motor operations. Check connection of the polygon motor harness/connector. Replace the polygon motor. Replace the MCU PWB.
  • Code: U1-03
  • Description: FAX board battery error
    The SRAM backup battery voltage on FAX PWB falls.
  • Causes: The SRAM backup battery voltage on FAX PWB falls.
  • Remedy: Check voltage of the SRAM back up battery. Replace the battery.
  • Code: U2-04
  • Description: EEPROM read/write error (Serial communication error)
    EEPROM access process error
  • Causes: EEPROM abnormality
  • Remedy: Check that the EEPROM is properly set. Use TC 16 to cancel the trouble. Replace the MCU PWB.
  • Code: U2-11
  • Description: Counter check sum error (EEPROM)
    Check sum error of the counter area in the EEPROM
  • Causes: EEPROM abnormality
  • Remedy: Check that the EEPROM is properly set. Use TC 16 to cancel the trouble. Replace the MCU PWB.
