    Re: CP3525 no magenta

    UPDATE

    have tried:
    Upper and Lower HVPS
    Y-M Laser

    all motor/sensor tests respond properly
    drum and developer rollers turn
    taping laser shutter nothing
    disable carts .. swap magenta to cyan and versa problem stayed with magenta slot
    swapped door levers .. no change
    visually checked and felt sensors... all look the same no springs outta place
    cleaned all contacts and innards
    stop test .. no magenta toner on drums nor belt
    engine test w/o formatter no magenta

    could it be the DCC? I mean shit that is about the only thing left!

    This seems interesting I feel for you though.
    Kinda crazy. Keep us up to date with this one. Yes DC controller... it sends the signal to turn on HV.
    Good luck!

    Gotta remove that to replace the fuser drive assembly. I did one the other day, and literally have a full six hours into this machine (finally found a tiny plug I had missed). Anyway, just got a call this morning for another one. Grrr.

    Anyway, I would think the magenta drum drive wouldn't work if it's the main drive ass. But then, maybe there's a different drive for the developer section. You might try to see if you can get to the dev roller and mark it somehow, to see if it's turning. Maybe it's just the developer motor on the drive assembly.

    i did mark developer roller.. mentioned that in the update. and yes developer drive is part of that same gear train.. it drive off of the drum drive gear no individual motor for the developer.
