Aficio 250 Need Service Code To Adj Drum

[mncopyguy]

Hi I Was Trained On Sharps And Canon's Not Ricoh's So If Someone Could Help Me I Need To Adj The Elec Value On A Aficio 250 So It Will Remove Shading

I didn't work on very many of these, but I pulled these two entries out of Goose's. I hope it helps.

Background:
Change SP2-912. (What is it? From what to what?)
On A224 set SP2-999 to '0', SP2-996 to '120', SP2-994 to '10', SP2-911 to '2', & SP2-201 to '600'.
I believe that this machine has a digital display, so you can see what each SP means.

You have not given enough information to evaluate the problem . Carrying out the adjustments mentioned will possibly only mask the fault.
Ie : SP2-912 only adjusts Fuser Temp.
The Copier may only require a new PCU [ All-In One] which will self adjust on replacement.

What i strongly believe that your Pcu is overtone..there is no way to adjust the drum value if so.What you need is a new drum(PCU) or you could try to adjust the TD sensor and the toner turning speed this would required skill check the value of TD sensor sp5-220..but my advice to you just change the whole PCU..solve all the problem.

Hi
This copier was never great on copy quality from what I remember. Try what zkafs suggested, but don't expect great copy quality, even after you replace the PCU.
