Looking for common issues with a single color from all you Konica-Minolta gurus out there.

C352 presents edge-to-edge Magenta midtone background in full, auto or single color modes. Glass copy, print & internal test print. K-only seems fine.

M imaging unit has been replaced and issue went away for awhile, then came back. Power seems fine without long term monitoring.

Scratching my chin.

I'm thinking in terms of HVPS issues... Maybe not. Don't get to play with a lot of theses. Usual genre is C550, C552 & pro C6500/6501 classes.

Thanks for your feedback.

(edit)

Btw, saw the PRCB & possible poor PH connection hits in Solution guide... The latter, then former, will probably be my first angles of attack barring any better ideas.

Similar problems have usually been caused by a faulty HV1 board... I have replaced quite a few of these on various color Bizhub models.
