Error code C447 indicates problem with Fuser temperature problem.Get the thermister cleaned on the fuser unit.If the thermister gets faulty or dirty, it will not let the fuser unit heat to the required temperature and this will cause the problem.-------- Also check that all the door covers are properly closed, also inspect if there is paper jam got there, causing this error.------ But if all this is not helping, then thermister needs to be replaced.---- As per error code C447.------ This will help.Thanks.Helpmech.

All error code soloution of fuser unit Fuser Unit Error Status Counter
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
When this code is used, the current set value of the fuser status counter is displayed. Only "0" can be
manually entered, in order to restore the fuser unit to its normal operation, after the fuser unit related
error is resolved.
For further reason why the counter value differs despite the same error code, refer to 5.1.7 or 5.1.8
[Fuser unit related service call] in the Service Handbook.
0: No error 10: C47 (Reserved)
1: C41 (Once) 11: C47 (Reserved)
2: C41 (Consecutively occurs) 12: C48 (Reserved)
3: C46 (Reserved) 13: C49 (Reserved)
4: C43 14: C47 (Reserved)
5: C44 15: C48 (Reserved)
6: C45 16: C49 (Reserved)
7: C44 17: C47 (Reserved)
8: C45 18: C48 (Reserved)
9: C44 19: C49 (Reserved)
* Default: 0
Use this code to resolve the fuser unit related error (error code C41, C43, C44 or C45). Resolve the
error, and set "0" (or reset the counter), in order to restore the fuser unit to its normal operation.
Remember to resolve the fuser unit related error, and then reset to "0." also 447
