    hi for all
    the problem is the double-sheet detector not work...
    and I think these problem form the side lays
    and the way to adjast the side lays in the manual is not clear

    from manual:
    (Use the screwdriver to turn the adjusting screw until the
    adjasting plate can no longer by moved)

    *I turn the adjusting screw all way down and the adjasting paper 0.1mm can be moved

    *and which direction should I testing the movement?(DS-OS)

    and Thank

    Yes, we need to know the machine type and serial number. Also we need to know if its CPtronic or CP2000. If possible please provide software version.

    Stream feed GTOs are a little tricky to set the double sheet sensor. It may just need to be adjusted but it is also possible that you need a new sensor or a new amplifier. If you go to the service wrench 2 screen, then the v/a screen and scroll through your screens till you get to one that has two columns, EWK1 and EWK2. EWK1 position 1 and 2 are the operator and drive side double sheet detectors. Inch the press to 147 degrees and check the values in these positions. the values must be between 400-800. if you are getting a 0000 value, it is possible that the sensor or amplifier is bad.

    I have sold and installed full automatic double sheet detector on Both GTO single sheet and stream feeder.
    You do not need to adjust sensor sensitivity for any stock you run, plastic sheet, transparent film, cardboard except envelop or film with backing sheet.
    You don't need to remember or refering operating mamual for value, setting, timing degree or how to adjust, just like late model CPtronic, Mitsubishi, Sakurai or Komori.
