Hello everyone
I've got a machine that keeps coming up with sc543, I have tried 2 new fusers (thinking the first one was faulty), a PSU and a AC controller board also firmware is up to date. I have followed the bulletins to try and reset the error code using sp5-810-002 but it keeps coming up with "fail"
Can reset the code using 5-810-001 but error will come back after a few days. Any help would be greatly appreciated
