Digital input devices, such as scanners and digital cameras, can use the Windows Image Acquisition (WIA) driver model. Depending on the module being used, devices that use TWAIN, Kofax, or ISIS can also be used.
To use Windows Image Acquisition (WIA) digital input devices to acquire images, the WIA Windows service must be configured with an Automatic or Manual Startup Type. For more information on WIA, including a complete list of devices compatible with WIA, see http://www.microsoft.com.
