All error code soloution of fuser unit Fuser Unit Error Status Counter
Purpose
When a fuser unit related error (error code C41, C43, C44 or C45) occurs, the set value of the fuser status
counter varies, depending on type of error.
Displaying and checking the set value of the fuser status counter can analyze a cause for the error. If
any of "2 to 9" is set at the fuser status counter, the fuser unit will not be operated for safety reasons.
After the fuser unit related error is resolved, if "0" is set, the fuser unit will be operated as usual. If any of
"10 to 19" is set at the fuser status counter, the fuser unit will be operated as usual, even if "0" is not set
after the fuser unit related error is resolved.
C41: Thermistor or heater abnormality at power-ON
C43: Thermistor abnormality after abnormality judgment
C44: Heater abnormality after abnormality judgment
C45: Thermistor abnormality during printing
C46 to C49: Reserved
