sc543 mpc4502

**blanka** · 06-27-2014

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

How susceptible is the area to power problems?

Is the power being supplied from the outlet the machine is plugged into OK?
If you've replaced all those parts with no success, you may want to check that if time permits. Maybe at least print out service mode 5-990-004 if possible and see the timing of the error codes in relationship to construction or energetic storms in the local area.

I have not tried a different power outlet as there is a shredder plugged next to where the machine is plugged in and it is working fine but that is something I can try. The timing of the codes seems to be random as there is no construction nor storm in the area.

I would suggest that you either move the MP C4502 or the shredder. Ideally the MP C4502 should be on a dedicated circuit. The shredder can produce a large amount of electrical noise on the line. This could be the source of your problem.
