Attachment 29857Did you happen to build over the part in red (that is the ground plate) if you replaced pcu and developerbox as 2 units; you need to salvage this part from the old pcu.I dont know if it is included in the complete unit.

We are fully aware about that issue coz it already happened to us. Without that "ground plate", the problem will be light copies/prints. I personally double checked physically the drum unit and transfer belt unit and installed new HV board but still not ok. We had changed 3 PCDUs (yellow) already because of this problem.

Let me restate my previous post as you have not yet answered it. "Have you checked the machine side contact for the charge roller? This sounds like the yellow drum is not being properly charged."

I think you have a point, let me update you tomorrow. Thanks a lot.

can I just ask what you mean by "build over the part in red". I have a call which has been escalated to me as the prints have gone light and I think drum and dev assemblies have been replaced. I assume you mean you can rebuild the unit without the red plate?

Just the opposite. You need to use the highlighted part from the old machine.
