    Hi,
    Your machine may have air leakage. Try to throw ON and OFF ink, dampening rollers on each unit. You should also check the pneumatic cylinder for impression mechanism. It's quite difficult to check it while the press is running.

    As Mathew mentioned, it could be also on of the pneumatic cylinders is damaged, in your case I think it is the pneumatic cylinder for feeder air, it is at the DS under the feeder cover.
    Send us feedback.
    Good luck.

    Dear sir,
    During machine running i was continuously checking the voltages at 11B14 and there was 5vdc permanent so it means there is no pressure drop in pneumatic compressor.is there another senoser which is responsible to check the pressure.
    Please guide

    Check
    i4 value in diagnostic/ current value
    Sak
    If Average value is going down below 17 then air error will come

    Ashok is right
    You can check the gauge of the pneumatic compressor, if the air is actually leaking or it is the pressure sensor.

    Surely there is a leak at the level of a pneumatic cylinder; remove the covers of the printing units and watch the pressurizing cylinders, dampeners, grippers etc ... You will find a leak at the time of printing
