Source is connected to the maximum supported number of applications

  • Symptom

    When you try to acquire images, you may get this error.

  • Cause

    The problem may occur when the source is not disabled completely after a transfer ends or is used by other applications.

  • Resolution

    • Check whether another application is using the source. If yes, close it and try again.
    • Set IfDisableSourceAfterAcquire to true and use CloseSource() to make sure that the source is closed after a scanning session.
    function btnScan_onclick() {
      DWObject.RegisterEvent("OnPostAllTransfers", function () {
      DWObject.CloseSource(); //close source before open
      DWObject.IfDisableSourceAfterAcquire = true; //close source after acquiring

    Reboot your device.
