Time chance pcu

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.

You will need to enter your Model #

u dont have to unless u getting poor copy quality.
its only an internal counter.

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).

A knocking noise is typically a bad bearing, probably in the fuser. You can try lubricating the bearings (once the fuser has cooled down) and see if the noise goes away. If not, the bearings might need to be replaced in order to get rid of the noise.
