    What's so special about it? Well it's the only way to calibrate the CCD. That's about it. =^..^=
    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.

    The new ISC improved the image immediately, but the directional lines in the gray were still invisible until I ran the U411 calibrations.

    And it's a Kyocera, not Konica.

    And yes, it's definitely an image processing issue. =^..^=
    OOPS! I should have known that. Sorry.

    I must admit i never had something like this on any Kyocera color machine. Thanks for sharing blackcat.

    I used GIMP specifically for that image since it's what I have available at work. It's one of the better freeware image manipulation software out there.

    Glad to hear that you solved it!

    We have the exact same problem on a 8353ci. Engine board was swapped I think then it caused this.

    The dp colours are fine duplex but anything that uses the platen glass has the weird purple tint to everything.

    The board you are talking about is the one directly connected to the lens under the glass?

    No sir, the ISC is on the back frame of the scanner (at least on the Alphard2 series).

    I don't have a service manual For the Iris2, but I suspect that the CCD is wired directly to the Engine PWB. All the image processing must happen there. =^..^=

    I suspect that you may not have purchased the CCD calibration sheets, or run the calibration. There is a data table that must be populated to define the CCD colors. =^..^=

    That's what it would print and then a photocopy of it off the glass.

    I don't think it has a connection board on the 8353ci. We changed the engine board and it returned to normal.

    The ribbon cable that goes from the image scanner carriage to the engine may have deformed contact pads that were making a poor contact or short. I have seen several instances of various ribbons over the years that get wonky with removal/reinstallation and have learned to inspect or re-trim on each handling of the connection. Most notably was a screen ribbon on an M3540idn new out of the box that had a purple screen background.
