Description: Transport motor malfunction
• The motor lock signal remains HIGH for a predetermined consecutive period of time while the transport motor remains energized. • The rack positioning sensor is in the blocked state when the rack motor remains deenergized. • The rack positioning sensor is not blocked a second time even after the lapse of a predetermined period of time after it has been blocked once while the rack motor remains energized.
Remedy: 1 Check the M1 connector for proper connection and correct as necessary. 2 Check M1 for proper drive coupling and correct as necessary. 3 Check the PRCB connector for proper connection and correct as necessary. 4 M1 operation check. PRCB PJ8-1 to 6 1600W: C-2 1650EN: C-2. 5 Change PRCB. 6 Change DCPU.
Code: 001B
Description: Rack rotation failure
• The rack positioning sensor is unable to detect the deceleration control position after the lapse of a given period of time after the rack motor has started while the rack motor is turning. • The count value of the edge of ON signal of the rack positioning sensor during each developing positions are not a predetermined value while the rack motor is turning.
Remedy: 1 Check the M2 connector for proper connection and correct as necessary. 2 Check M2 for proper drive coupling and correct as necessary. 3 Check the PRCB connector for proper connection and correct as necessary. 4 PS5 sensor check. PRCB PJ5-11 (ON) 1600W: C-11 to 12 1650EN: C-11 to 12. 5 M2 operation check. PRCB PJ5-5 to 8 1600W: C-12 1650EN: C-12. 6 Change PRCB.

Description: Duplex unit cooling fan motor malfunction
Remedy:
Code: 004C
Description: Ozone ventilation fan motor malfunction
• The ozone ventilation fan motor does not rotate evenly even after the lapse of a given period of time while it is being started. • The motor lock signal remains HIGH for a given period of consecutive time while the ozone ventilation fan motor is being rotated.
Remedy: 1 Check the FM2 connector for proper connection and correct as necessary. 2 Check the fan for possible overload and correct as necessary. 3 Check the PRCB connector for proper connection and correct as necessary. 4 FM2 operation check. PRCB PJ16-1 (REM) PRCB PJ16-3 (LOCK) 1600W: C-4 1650EN: C-4. 5 Change FM2. 6 Change PRCB.
Code: 004E
Description: Power supply cooling fan motor malfunction
• The fan motor lock signal remains HIGH for a predetermined consecutive period of time while the power supply cooling fan motor remains energized.
Remedy: 1 Check the FM1 connector for proper connection and correct as necessary. 2 Check the fan for possible overload and correct as necessary. 3 Check the PRCB connector for proper connection and correct as necessary. 4 FM1 operation check. HV CN2-1 (REM) HV CN2-3 (LOCK) 1600W: B-5 1650EN: B-4 to 5. 5 Change PRCB. 6 Change DCPU.
Code: 0092
Description: Transfer belt rotation failure
• The belt positioning sensor does not detect the transfer belt position detection hole a second time even after the lapse of a predetermined period of time after it has detected one while the transfer belt is rotated.
Remedy: 1 Check the PRCB connector for proper connection and correct as necessary. 2 PS6 sensor check. 3 Change Imaging cartridge. 4 Change PRCB.
