WIA Automation Library 2.0 does not support duplex scan


When scanning documents using an application that uses the Windows Image Acquisition (WIA) Automation Library 2.0, the application will fail to perform a duplex scan. The application scans one side of the document but not the second side.


This is a limitation of the WIA Automation Library 2.0.


You can avoid this problem by developing your application using native WIA 2.0 (Windows Visa and Windows 7) or WIA 1.0 (Windows XP).
