Hey everybody. Got a 622. Keeps kicking up sc543. Thermistors are ok. Found on rear of fsr unit a spring for jam door was out so it wasn't pivoting. Clnd thermistors. Yesterday after correcting it, i ran 240 clicks. Open & closed jam door. Turned off & on. Made 10 more. Hung around. Was good. At end of day popped sc 543 again. Chckd heat lamps connect, not burned. Where thermistors contact heat roller I can see aluminum core but slight. Never seen it code out cause of that. Mylar on thermistors not split nor rubbed out. Any thoughts.

check for fusing unit drawer(index6 p39 parts catalogue)
sc503 means fusing Lamps still on, no fusing temperature regulation
Check for TR401 and TR411 on power supply unit: change PSU -
