I have 1045 model, more times error sc546 comming

Enter in the service mode open the front door and turn OFF the copier.Unplugged,wait 10 seconds,plugged on close the front door and turn ON the main power switch.It is the total trouble reset and work 100%.

SC546 is htermistor reading in the fuser is not getting a correct reading.. this could be due to toner build up on the face of the thermistor open up the front of the machine the fuser is at top right hand side. there is a screw under it to release the unit. open the side dooor and you can pull teh unit out. have a look at the surface of teh rollers if they look shiny black they are ok if there is any wear on them they may need changing. to clear the code enter the service mode by pressing the yellow clear button at top of number pad then enter 107 then hold down the stop button till teh screen changes to sp mode,, you need to look for section 5.mode then scroll to 810 sc reset .. execute this and turn off the machine wait 5 secs and turn back on.. this should clear your code . if this keeps coming up the thermistors may need to be changed they ar cheap and you could change them yourself.. if you need more details let me know. Good Luck A
