010-320 Heat Roll Over Temperature Failure RAP

BSD-ON:10.1
• The Control (Center) Thermistor detected a temperature higher than the specified value.
• The Rear Thermistor detected a temperature higher than the specified value.
Procedure
NOTE: When [010-320] occurs, NVM[744-220 FuserOverTemp]=1. After repair, change it to
NVM[744-220 FuserOverTemp]=0.
Check the resistance of the Control (Center) Thermistor between J600-5 and J600-6 (BSD
10.1 Flag 2/Flag 3). The resistance is 3k Ohms or higher.
Y N
Replace the Fuser Unit (PL 5.1).
Check the resistance of the Rear Thermistor between J600-2 and J600-4 (BSD 10.1
Flag 3). The resistance is 3k ohms or higher.
Y N
Replace the Fuser Unit (PL 5.1).
Check the wire between P/J410 and J600
wire between J410 and J600 is conducting without a short circuit.
Y N
Repair the open circuit or short circuit.
Check the wire between P/J401 and P/J523
Flag 4). The wire between J401 and J523 is conducting without an open circuit or a short
circuit.
Y N
Repair the open circuit or short circuit.
Replace the Fuser Unit (PL 5.1). If the problem persists, replace the Power Unit
