BSD-ON:10.1
• After the Main Lamp turned On during warm up, the Control Thermistor did not detect
READY temperature within the specified time.
• After the Main Lamp turned On during standby, the Control Thermistor did not detect a
specific temperature within the specified time.
• After the Sub Lamp turned On during standby, the Control Thermistor did not detect a
specific temperature within the specified time.
• After the empty rotation started, the Control Thermistor did not detect the empty rotation
finishing temperature within the specified time.
• After the Main Lamp turned On during printing, the Control Thermistor did not detect a
specific temperature within the specified time.
• After the Sub Lamp turned On during printing, the Control Thermistor did not detect a spe-
cific temperature within the specified time.
Initial Actions

• Indoor Temperature
Procedure
NOTE: When [010-327] occurs, NVM[744-220 FuserOverTemp]=1. After repair, change it to
NVM[744-220 FuserOverTemp]=0.
Check for paper on the Fuser. The Fuser has no paper wrapped round it.
YN
Remove the paper.
Check the installation of the Fuser Unit. The Fuser Unit is securely installed.
YN
Install the Fuser Unit securely.
Remove the Fuser Unit. Check the conductivity of the contact points of the Thermostat. The
contact points are connected.
YN
Replace the Fuser Unit (PL 5.1).
Check the resistance of the Main Lamp between J600-3 and J600-7 for an open circuit or a
short circuit (BSD 10.1 Flag 1).
The resistance of the Main Lamp is 100 ohms or lower.
YN
Replace the Fuser Unit (PL 5.1).
Check the resistance of the Sub Lamp between J600-1 and J600-7 for an open circuit or a
short circuit (BSD 10.1 Flag 1).
The resistance of the Sub Lamp is 100 ohms or lower.
YN
Replace the Fuser Unit (PL 5.1).
Check the resistance of the Control (Center) Thermistor between J600-5 and J600-6 (BSD
10.1 Flag 2/Flag 3)).
There is no open circuit in the Center STS and the resistance is 3k
ohms or higher.
YN
Replace the Fuser Unit (PL 5.1).
Check the resistance of the Rear Thermistor between J600-2 and J600-4 (BSD 10.1 Flag 2/
Flag 3)).
The resistance is 3k ohms or higher.
YN
Replace the Fuser Unit (PL 5.1).
Check the wire between P/J410 and J600 for an open circuit or a short circuit (BSD 10.1 Flag
2/Flag 3)).
The wire between J410 and J600 conducts and is free of a short circuit.
YN
Repair the open circuit or short circuit.
Check the wire between P/J607 and J600 for an open circuit or a short circuit (BSD 10.1 Flag
2/Flag 3)).
The wire between J607 and J600 conducts and if free of a short circuit.
YN
Repair the open circuit or short circuit.
Check the wire between P/J401 and P/J523 for an open circuit or a short circuit (BSD 10.1
Flag 4).
The wire between J401 and J523 conducts and if free of a short circuit.
YN
Repair the open circuit or short circuit.
Replace the Fuser Unit (PL 5.1). If the problem persists, replace the Power Unit (PL 9.1). If the
problem persists, replace the MCU PWB (PL 9.1).
