    C454e cyan developer

    Howdy Folks,

    I have a couple of these C454e machines that are eating cyan developer units. One machine just yesterday has only 9000 copies on the unit. I replaced the drum and developer previous to this change. I just sent them back to KM for their YPP. When I take out the unit there is not a brush on the mag roller, seems to be all gone? The waste toner box is a little heavy, so I think that it is going in there. The one machine that I was just at yesterday has over 1 million on it and the other one has not quite a million. One has G00-K2 and the other has G20-M1. Just throwing that out there, because the cyan developers are always backordered.

    Thanks
    KEN

    Make sure the other drums are not way past yield. Drums of another colour can cause this symptom if they are too old.

    None of the other drums or developers are over life. They are about half way through their nice little life.

    On a bizhub C658 I had a bad HVT that consumed developer in seconds. I'd install the cyan developing unit and with 10 seconds it was empty. =^..^=
    If you'd like a serious answer to your request:
    1) demonstrate that you've read the manual
    2) demonstrate that you made some attempt to fix it.
    3) if you're going to ask about jams include the jam code.
    4) if you're going to ask about an error code include the error code.
    5) You are the person onsite. Only you can make observations.

    Corkscrew output, check:
    - other consumables over life
    - HVT or HVT contacts leak
    - clogged filters
    There were some bulletins here in other topics, maybe copyman posted them, as I don't have them handy.

    We've been facing this on multiple machines for years always cyan dev that gets depleted.

    All drums, transfer belt & filters new, remaining devs well in life replaced cyan dev unit after a few thousand dev is depleted again.

    Seen it on the C452/C552 & all the 4 series machines not yet on the 8 series so there is hope!
    Let us eat, drink, and be merry, because tomorrow we may die!

    What about HVT lines on these. Did you check contacts for evidence of arcing? That can be tricky fo trace.
