I had this several times and developer unit was shot.
The wierd thing is you already replaced it...

Thanks TMaged, found the QA. Rarely do I go to the portal because I hate windows explorer.

Anymore if we have time we just replace these old style augers even if there's no sign of a CQ problem. prevents the inevitable future service call.

We were getting this but was a yellow background. Check the developer and main charge bias settings. (Can't remember which maintenance mode.) Adjusted to "factory specs" and voila all was good again! Mind you this was after a full maintenance kit and HVU board replacement.
