    c451/550/651 Developer Dumping

    I am having a problem and hoping someone may be able to steer me in the right direction. I have a c650 that is dumping black developer. The problem started after I replaced the drum in the imaging unit. It was a relatively new imaging unit and the drum had a couple of small scratches on it (not sure how they got there). I didn't want to trash the whole imaging unit with a new (costly) imaging unit so I purchased a new drum and then disassembled and reassembled the imaging unit with the new drum. After replacing the imaging unit in the copier it started immediately dumping black developer. So I took that out and replaced it with a brand new complete imaging unit. The same thing is happening. It immediately dumps black developer.

    Any ideas on what I can do or check are greatly appreciated. Thank you!

    There are a few bulletins for this. I'll try and dig them out and post later
