    Hi to everybody

    Sometimes we have the next problem on printing - stripes or waves (see the attachment).
    This is electrical or mechanical problem ? Where I can start looking to fix it ?

    Thanks to all

    Adjustment of the pressing springs of the rollers. And then a new adjustment of the rollers.

    Hi Drukman!

    There is a picture with rollers in the attachment.
    The rollers 11.4 and 11.5 are absent.
    We have only 402, 21 and 31 rollers. But they don't have the pressing springs.
    Which of those rollers I must to adjust ?

    PS
    The stripes appear only sometimes and on different printing sections +C*.
    But sometimes is all ok .
    I can't find any regularity.

    Thanks.

    you might want to try printing magenta before cyan for this particular form.
