PCU? fax\printer machine says time to change PCU...is this something I can fix myself or does machine need serviced?

Hi, PCU stands for photo conductor unit, most of us call it a drum unit. You should be able to order from any office supply. It is easy to install and will come with directions.

I've never seen a message like that with the 0390H code. There is no mention of that code in either the user manual or service manual. The closest thing is the sc390 code, which means either the toner density sensor or the developer has gone bad, and typically replacing the PCU can fix that problem.

If the new PCU doesn't fix the problem, you might want to try calling Ricoh for support, since their documentation doesn't mention that code.

Order a new PCU from Ricoh. Power off the machine and replace the pcu.
If you try and cheat it it will run for a short while and then lock-up breaking some gears. Cheeper just to order a pcu. Check Ebay, i see alot of Ricoh supplies there.

you need to replace the Photo Conductor unit (drum unit).

hi,
as long as copy quality is not a issue you can use it. If you order a photoconductor you can replace it by your self.
