    you have too much CYAN ..not green. Y & C = G.

    look at the dispensing ratios

    gradation adjust is not PARTS but a service mode function. replacing parts should be done AFTER calibrations/adjustments have failed.

    So you're not even going to look at the consumables, like imaging units? In addition to cyan massively overtoning, magenta is massively undertoning. You must have been talking to the hotline: "Oh yeah, it's got to be a board..."

    =^..^=

    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.

    Hi all,
    I would like to mention that I am a field engineer so the first thing I have done was to change the IU. When I say green I understand that Green is mix of Cyan and Yellow. So any feedback would be much appreciated. Thanks all
