 Procedure

  1. Make sure that EEPROM/1 and EEPROM/2 are mounted in their respective correct positions.
  2. Check to see if the EEPROM is mounted in a reverse direction.
  3. Check the connector from MFPB to EEPROM for proper connection and correct as necessary.
  4. Replace MFPB. (Part# A797H02118)
  5. Replace EEPROM/1 and EEPROM/2. (Part# V864800107)
    1. Replace the current EEPROM with a new one.
    2. Replace the following components with new ones: When the transfer belt unit and the fusing unit have been replaced with new ones, perform [New Release] in the service mode. When the transfer roller has been replaced with a new one, perform [Counter clear].
      • Imaging unit/Y,M,C (C Part# A85Y0KD, M Part# A85Y0ED, Y Part# A85Y08D)
      • Developing unit/K (Part# A85Y03D)
      • Drum unit/K (Part# A85Y0RD)
      • Transfer belt unit (Part# A797R73400)
      • Fusing unit (Part# A797R70211)
      • Transfer roller (Part# A797R71811)
      • Feed roller (Tray 1/2 Part# A00J563600 / Manual bypass tray Part# A00F623201), pick-up roller (Part# A5C1562200), separation roller (Tray 1/2 Part# A00J563600 / Manual bypass tray Part# 4658015106) (including options)
    3. Turn ON the main power switch and check to see that warm-up is started. Make sure that malfunction codes other than C2650 or improper IU/TC placement is not detected.
