    Bizhub 600 write unit

    This machine with almost 2,000,000 on it started codeing 4704 and making the copies coming out dark grey all over, almost as dark as the text. I have pulled the write unit and will put it in another 600 tomorrow to test it. Has anyone else had an issue with this code?

      The write unit tested fine, then I found that the charge was touching the drum and causing the problem.

        Almost every time I PM one of these, I have to go back into the drum section and pull the charge unit out to fix this problem. It looks fine going back in, but within 200 copies, I am pulling developer, or have CQ issues. Any tips on the correct way of replacing the charge unit so these problems don't pop up? Emujo
        If you don't see your question answered in the forum, please don't think it's OK to PM me for a personal reply...I do not give out firmware and/or manuals.
