    You'll have to be much more specific than "Heidelberg 4 unit". Model, year of manufacture would help tremendously.

    Machine SM 102 -4P3 when you start production each unit impression engages but immediately disengages while still in production... machine is not showing any error

    Are you sure that the margin of the paper you are using is correct at the level of the margin table?

    You are printing a 0.08 splicer paper so this is the top white paper.
    check if the margin of the sheets is good at the level of the margin table.
    When the sheet arrives at the level of the front cleats, the sheets must be well flattened above the control detector.
    Put some leaf offal to keep the leaf flattened.
    If you have an sm 102 with a tablecloth, adjust the suction air of the feed table so as not to push the sheet too much against the front tabs.
    If you have an sm102 with holding brushes try to adjust them so that they are flush with the sheet when jogging on the front cleats.
    Let me know

    If you can change the type of paper will be better to advance to the diagnosis.
    Try coated paper or cardboard
