    The problem is in swing griper and impression cylinder paper transfer.

    This is in the middle of sheet? It could be the transfer grippers that move paper from stack to swing gripper.

    hello, pass the paper slowly or suddenly to see which of the grippers of the machine causes it. Thank you for the return

    Impression sequencing roller switch (normally Klockner-Moeller) work. Usually not electrically fault, most often pivoting lever or roller plastic components worn out.

    If you open the side OS you will see little blue boxes with a small roller those are the switches that enable the impression. Call an electrician to measure those switches. If you check up your manual parts there is a page that details where those switches with numbers (eg e28).

    Most often, the electrical is OK, you must look for worn out plastic parts.
