AF 2075 (Dsm675) gray backround

[nb321]

Hi guys,
i have problem with 2075 machine. printed image is full gray backround, only area around text should be is white. The SC 352 or 355 are logged. I've changed whole drum unit from another machine, whole developer unit, corona harness, corona unit, all grounding are clear and looks ok, and still it's same error. any idea?

Wow, that's impressive. I'd be looking at IPU, charge power pack or laser unit next.
