Enter the SP mode and execute fuser SC reset. Then turn the machine OFF and
ON.
If the SC occurs again, do the following steps. Check if the SC reoccurs by cycling
the power after each step.

After turning the fusing lamp ON, the pressure roller thermistor (center) has failed
to reach -40 °C continuously for 30 seconds. AND the power supply voltage is
lower than specified voltage.

After turning the fusing relay ON, the pressure roller thermistor (center) has
detected over 248 °C continuously for 1 second.
Error Name/Error Condition/Major Cause/Solution
Thermistor is deformed or not in contact
Power supply voltage low
Overheating protection device triggered (blown fusing thermostat)
Fusing drive non-rotation
Check the input power source and reconnect the cable to the outlet.
Replace the pressure roller thermistor (center) (TH3).
Replace the fusing thermostat (TH1).
Replace the fusing unit.
Replace the EGB (PCB1) or/and the PSU (PCB4).
