This copier is driving me mad the first call was for a fuser error that was caused by the belt being split and the thermistor was damaged by the belt .I replaced the fuser belt and the thermistors witch comes with all 3 thermistors and the oil and cleaning roller . Then it keeps every few hours going sc541 im sure the rollers and belt are in correct and the bearings are all ok. I have today changed the fuser harness at the rear of the copier and the one that connects t the thermistors and it came back in this afternoon any one had this problem as im running out of ideas
