Handling Errors

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();
        });
        DWObject.SelectSource();
        DWObject.CloseSource(); //close source before open
        DWObject.OpenSource();
        DWObject.IfDisableSourceAfterAcquire = true; //close source after acquiring
        DWObject.AcquireImage();
    }
    

    Reboot your device.
