I have a customer with an 11100 (ricoh) that continually has displayed the warning for the PCU cleaning unit. Last night it finally changed to "Replacement Required:Cleaning Unit for PCU". I have not been there yet for the current issue and he is gone until next week so I thought to do some research.
I have rebuilt this unit in the past and have never been able to make the warning go away and as long as it was working we didn't really care too much. Now that it is down it is, of course, a different story. Only once in this machines history has the unit been changed and not displayed the warning message. That was the first time at around 900k when I had a new unit. since then I have been rebuilding one of the 2 units I have while the other is in use. Usually it will go 800k to 1M pages (LTR). It currently has about 200K on the drum and rebuilt cleaning unit and just under 4M total. A typical rebuild is all the gears, both blades, lube bar, apply brush and drum. On the first rebuild I did I didn't have the gears and thought that may be the reason I was getting the warning. I promptly ordered a set and installed them and made no difference.
I have been through all the service modes and user modes resetting maintenance counts.
In service modes I will go to 7-266 and reset 005-11 for the cleaning unit, 012-017 for the main charge corona (when applicable) and 018 for the drum itself. If memory serves me correctly these are already reset if it has been done in user modes but not always, so I always check them.
Is there something in this unit that is triggering this? Is it really required to replace the unit?
Thanks in advance, and sorry for the long winded post.
Oh yeah, I posted this in the Ricoh section as well.
