How do I enable double-feed detection in my Ranger application?

[Bryan Clark]

When it comes to enabling double-feed detection, older versions of Ranger and newer versions behave differently.  It is best to upgrade to the latest version of Ranger whenever you can.

To enable double-feed detection, try making the following call when Ranger is in the TransportChangeOptions state:

  Ranger.SetGenericOption("Optional Devices", "NeedDoubleDocDetection", "true");

To disable double-feed detection call:

   Ranger.SetGenericOption("Optional Devices", "NeedDoubleDocDetection", "false");

If double-feed detection does not seem to work after setting the option above, look in Ranger's driver options file for your scanner.  (see Where are the Ranger INI files located?) If you find double-feed options in the driver options file, you can set them by calling Ranger.SetDriverOption().
