This is the second one I have seen doing this I am getting blank copies and there is some developer dump Good coronas, The last one we ended up upgrading the customer but this is not an option on this one

I just started a new job and would love to walk in the door on my first day with a solution. Assume the simple stuff is done and go from there.
Thanks and anyone near Raleigh welcome me to the area (from SE kans)

Read this post, it has lots in common with your problem: Copy quality

Try replacing Drum potential sensor and develper at the same time. I have seen this many times. The sensor throws the bias off and causes it to pull dev and make the copies washed out.The sensor comes with the board that is over the bypass.
