Initial Actions
• Power OFF/ON
Procedure
Check the installation of the Fuser Unit. The Fuser Unit is securely installed.
Y N
Install the Fuser Unit securely.
Check the resistance of the Center Thermistor between J621-5 and J621-1
resistance is 3k ohms or higher.
Y N
Replace the Fuser Unit (PL 7.1).
Check the Center Thermistor wiring between
circuit (BSD 10.1). The wire between P/J410
cuit or a short circuit.
Y N
Repair the open circuit or short circuit.
Replace the Fuser Unit (PL 7.1). If the problem persists, replace the MCU PWB
