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.
