This type of drivers (Twain Data Source On WIA) are not supported in FineReader 14 and FineReader PDF 15. If it's possible, install the TWAIN driver downloaded from the scanner manufacturer’s website.

More details: Microsoft provides a TWAIN wrapper for some WIA drivers. This allows applications that cannot use WIA drivers to see these WIA drivers as TWAIN. When using a TWAIN driver with FineReader 12 or earlier versions, you may see a TWAIN driver that begins with "WIA -".
