    Try switching off the drum potential sensor. SW 6 bit 7. Just an idea. Not sure what that can do to the charge value if its faulty.
    Whatever

    Strip & clean all the contacts, blow out all stray toner & developer this may help stray dev causes shorts.

    951 has a transfer belt?!? Oh the days when you could just turn the light off in the room open the door and key the door switch and watch for the arcing. I am surprised, I assumed the high volume monochrome machines would still have corona wires.
