Bizhub C452 printing PINK backgrounding (and P21, P28 code)

[PanaTech]

I have recently installed a new Bizhub C452, and after 2000 B/w printer, and 800 color print. It suddenly print a think layer of pink at the background. It work ok when printing b/w, but whenever u print/copy color. It puts a layer of magenta on the background. I cleaned the IDC sensor, and it won't work. I replaced the drum/dev unit, and wont work.

Any ideas? am I missing something?



Thanks in advance

It could be the transfer belt itself. I have had them fail and stick when printing colour. It happened to me on cyan, but same diff.

I could be that the run up procedure was done incorrectly also, but usually swaps between C & M when backgrounding. The P codes also point more to a belt failure rather than run up being done incorrectly.

problem solved.

It was the laser. going to claim warranty for that.
