    The first ink form roller jumps on the operating side.
    When I look through the cover on printing press at the first form roller, it moves too much and jumps a little.
    The roller has no contact to the plate and cannot be adjusted.
    I have removed it and measured 70mm.
    The roller lock closes very easily just so engages.
    The roller mount does not move much, I thought it was something broken. I have found nothing.

    I put everything back together and adjusted.
    Roller could also be adjusted to the plate. Thought the problem was solved......but no

    Do you have any ideas?

    The bearing of the roller seems ok.

    Remove the bridge (tandem) roller and try.

    If bridge is too tight it will cause bounce.
