    Issue on cyan unit konica C1085

    Hi,

    We have issue when printing 100% cyan on left side of the sheet.
    When we print picture or image not containing excess cyan, there is no problem.

    We change, développer, drum, corona, transfert... nothing work

    here attached some picture, you can see on some place there is lack of cyan.

    Thanks,

    You can print the test Pattern 75, 58, 43 to isolate the issue..!!!
    seems something blocking the PH filter Glass,,,

    Thanks

    Cyan PRINTHEAD/ROS/Laser

    I don't think you are a tech..
    get out your USER manual look thru 'troubleshooting' Image Quality.. follow the suggestions.

    Re: Issue on cyan unit konica C1085

    I'm looking at your photos and find an interesting discrepancy with your description: the color at the right of your photo reads C:0 M:4 Y:8 K:68

    I detect variations in M to left increasing to 14 then decreasing to 4, and K 68 diminishing to the left to 40. But there isn't a single pixel of cyan in the photo anywhere. I don't think this is a very good print sample, especially if you suspect cyan. Try this:
    =^..^=

    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.
