Savin c4540/Ricoh c4500 open door prob.

[jper34]

Hi Folks,
m working on Savin C4540 color copier thats indicating the right door being open. I replaced front/right door interlock switck, made sure both
micro-switches were making contact. All other switches seem to be working fine. Could there be another switch, either photo-interrupter or micro, that Im not
seeing? aaive read something about a power supply could cause this, Im just not sure, I did check fuss(ohmed out) fuses that I could see
on power supplies/boards, unless theres a hidden pcb. Any help would be greatly appreciated, as copier is down, and I am just not finding the cause...
so thanks, open to any and all help ..!!

Thanks,
Jaime

Have you tried jeppoing the right switches ? (push a piece of folded paper or flat screwdriver in to see if turns off the door open warning?)

There's a set switch at the top of the side door near the junction gate gear. The harness that runs to that sensor frays after time and gives this issue.
