Check the surface of image transfer roller. Check if there is any dust or damage on the fusing roller surface.
Fuser Control
The fuser is heated by the heater lamp, which is powered by AC voltage. When the power supply board receives a FUSER LAMP signal from the engine controller board PWB-A , the power supply board PWB-E supplies the AC voltage to the heater lamp. This AC voltage is cut by the interlock switch when the case is open. The fuser temperature is detected by the thermistor. Based on the TH1 signals from the thermistor, the engine controller board PWB-A controls the fusing temperature 165 C, 329 F using...
