Ricoh MP C 2500 all the colors slightly become yellow

[TecnocopyVI]

Hi guys,
I have a problem with Ricoh MPC2500, when stamp inner tests i don't have this wrap yellow, but when I make copies (color) all the colors slightly become yellow in the same point. I have tried to change OPC Yellow,CCD,RAM,Yellow Development but the problem persists.

Someone can i help me? Thank you very much!

If this is only happen in copy mode there must be something wrong with the scanner.

I suppose you've clenaed it properly and tried an ACC? There may be also something wrong with one of the scanner SPs. Perform a NV Ram backup, reset all scanner related SP stuff and check the results.
