The ScanSnap series does not support TWAIN drivers or ISIS drivers.
ScanSnap Home must be installed as the driver.
Scanning applications that support TWAIN or ISIS drivers cannot detect ScanSnap devices in the scanner list and therefore cannot be used.
To import scanned images into an application, please save the images onto your computer temporarily, and then upload them to the application.
