Can a PCU Unit (Loss of ground between the unit and the copier) from a Ricoh Aficio 1035 cause an SC350 error code? Any help appreciated. Thank you.

What else have you checked?
It would be stupid for me to send you off looking for wrong things, so I need more information.
Thanks.
I replaced the id sensor because of overtoning; was going to replace the dev. unit but when replacing the id sensor noticed that it was unplugged9the one I replacing was a new one I installed last visit. I had switched toner supply to pixel. After replacing the id sensor I switched toner supply back to sensor. Before leaving I checked the drum and noticed it was black with toner which I've seen on this model and others just not sure what causes this leading eventually to a SC-350.
Thanks!!!
I used to have a real knack for not getting the PCR installed properly in these PCU's, so that it didn't contact the drum entirely. Black copies and SC's were the result.
Beyond that, I think you're looking at an HVU, or BICU, and that's just plain nonsense on a 14 year old box.
Bad grumd of the drum shaft is not uncommon - back then we used some modifications like sort of copper-spring plates touching the rear end of the drum shaft. I also recall I wicked quick and dirty improvisation I did with a paper clip LOL
I also wouldn't recommend start ordering expensive stuff for this machine even if I like it more than the current engine^^
maybe a hard drum. Did I hear someone playing Taps????????

Ive had the Brass screw holes break on the dev unit where it connects to the drum part of the PCU cause sc350 and blk copies before.
I believe the SC350 can also be caused by the Timing Pulley (AB030574) that is on Drum Shaft slipping. It is "D" shaped and can cause problems when it wears and you have a very old machine. When this pulley goes you also get partial images, black bands, shrunk images in your copies. Take the Flywheels off and take a close look at this pulley.
The drum shaft housing uses what is supposed to be a conductive ball bearing for the drum shaft. With age, it loses its conductivity. Test from the drum shaft to the outer race of the bearing. It should be less than 1 ohms.
I have also encountered machines where the ground contact for the doctor blade is missing from the back of the development unit. This will cause dirty background.
