    C759 Backgrounded prints, only from scans

    Hi all, very interesting one. I myself didn't attend it was other tech's, 3x of them so far... I'm expecting to go there next week, I'm in a different city...

    MC: Develop Ineo+ 759 Problem started: all of a sudden (supposedly)

    Machine prints original other PDFs/word docs etc fine, no issue. Internal charts etc fine no issue. Scans from machine viewed on the computers, no issue. Problem arises when the machine PRINTS scanned documents ONLY from other C759's and also itself from the same office. There are 5x of these C759's in this office and only this machine has this issue.. Text and graphics are illegible and look like they are all highlighted in black.

    Work done so far apparently:
    Compare settings lists from other C759's in office and set the same, no change
    Firmware (more than one version), no change
    Clear all data and format, no change
    Replace MFPB, no change
    Replace HDD, no change
    Try all combinations of different scan settings and try and compare, no change
    Try all different drivers etc, no change
    Try different computers, apps etc, no change
    Try same documents on scanned to usb and print directly, no change

    It actually works fine other than this, no other issue other than printing scanned documents, and only from C759's including itself... LOL
    Test print a scan from a C364e and works.... Test print a scan from a HP MFP and works....

    I have tried to replicate an issue with all forms of setting changes in our office here and none have produced images even remotely like this.

    Original documents like above I have successfully printed on a C360i, C368 and C754e with no issue, all perfect, no issues.

    Must surely be a setting issue that can only be resolved with resetting/replacing nvram? I thought the nvram initialization tool stopped working kike the 8 series after a certain version? I'm not familiar so much with this model only the C360i/C658/C454e etc. I had suggested the coordinator got the field tech to change the software switch that converts it to a KM so it resets a lot of the background settings then try to see the result if any change and use km driver. Any feedback appreciated on this one!

    Print a management list from a working machine and compare it to the management list from the machine having the problem. You might find a setting off.

      Have you tried a different file format when scanning ?

        I have seem issues like this ... usually associated with a specific driver or setting, or a specific application.

        Have you tried printing a PDF scan via a USB stick? That would rule out the entire network side of the equation. Or sending a print capture directly to the printers IP address?

        When you view the scans (before printing) are there visible defects, at higher enlargement? Here is an example that I pulled out my remaining hairs for:
        Hold on a second: Excel is acting weird ...

        Kip 3100, Shaded bands in the feed direction on prints. Background is present, but not visible in PDF original documents. In this case the background was occurring during scanning of printed originals on a Toshiba e Studio 2830C. To confirm presence of background in the PDF, print the image rotated 90 degrees to determine if the background rotates also. If yes, work on the scanning issue.

        eStudio 2330C, 2820C, 2830C, 3520C, 3530C, 4520C, Masherbrum, Wavy background on images through DF. Rectangular blocks of background on scans 300dpi, Printed Image original type, PDF. Only seen on resulting 300% prints of scanned image. DF height is mis-adjusted too high. Skewing and buckling originals. Scanning background adjustment requires tweaking. Lower DF left hinge to an even 1mm spacing. Clean optics. Perform color calibration. Adjust Image Quality Adjustment Scanning > Background Adjustment Printed Image 05-1071 > set from default 50 to 40.

        I really hope that you're not headed down this road. =^..^=

        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.
