Hello!

There's a problem with the fuser unit (Unstable fusing temperature).
Check the thermistor, there is toner on it. Clean it gently and carefully with alcohol and then you probably must reset the SC counter, similar to the way you do after replacing the fusing unit.

I didn't understand exactly what happened:

1. Did you put a new FUSER UNIT in the printer and the error is still here? If so, YOU MUST RESET THE ERROR IN SERVICE MODE.

2. If you put the FUSER UNIT in ANOTHER printer and the error appeared there, CAREFULLY CHECK THE THERMISTOR, LAMP, THERMOCOUPLE AND SO ON. You will need to reset the error for the other printer too, in SERVICE MODE.

Good luck!
