Confidential
 Error code 0900
Detected irregular power supply for more than 100 times.
 Error code 0A02
Detected a main fan failure.
 Error code 0B01
An error occurred in the high-voltage power supply PCB ASSY while operating.
Error code 0B02
An error occurred in the high-voltage power supply PCB ASSY when the machine was in the
ready state.
<User Check>
• Turn OFF the power switch. After several seconds, turn ON the power again and check
that this error is reset.
Step Cause Remedy
1
Low-voltage power supply PCB
failure
Replace the low-voltage power supply PCB
ASSY. Refer to “1.3.31 Reset counters for
consumable parts (function code: 88)” in
Chapter 5 to reset the irregular power supply
detection counter after the replacement.
2 Main PCB failure Replace the main PCB ASSY.
Note:
• The irregular power supply detection error of the low-voltage power supply PCB (error
code: 0900) occurs when there is a large distortion in the power supply voltage
supplied to the machine. In this case, if the same power supply is used, the same error
may occur even when the low-voltage power supply PCB ASSY is replaced. Ask the
user to review the installation environment.
• Do not reset the power supply PCB counter before replacing it with a new one. It may
cause fire.
Step Cause Remedy
1
Connection failure of the main fan
harness
Reconnect the main fan harness.
2
Connection failure of the toner
amount detection sensor PCB
harness (light emission)
Reconnect the toner amount detection sensor
PCB harness (light emission).
3 Main fan failure Replace the main fan.
4
Low-voltage power supply PCB
failure
Replace the low-voltage power supply PCB
ASSY.
5
Toner amount detection sensor
PCB (light emission) failure
Replace the toner amount detection sensor
PCB ASSY (light emission).
6 Main PCB failure Replace the main PCB ASSY.
<User Check>
• Replace the drum unit. (corona wire breakage)
Step Cause Remedy
1
Connection failure of the HVPS
flat cable
Reconnect the HVPS flat cable.
2
High-voltage power supply PCB failure Replace the high-voltage power supply PCB ASSY.
3 Main PCB failure Replace the main PCB ASSY.
