Digitech supports scanners that are ISIS certified. To check if your scanner is ISIS certified head over to https://www.opentext.com/support/scanner-drivers to see if the scanner in question is compatible.

Alternative

If you cannot locate the scanner in question on scannerdrivers.com, there is another site you can use: https://www.emc.com/microsites/scannerdrivers/index.htm

This site has a few older scanners, so a good place to check just in case the scanner you are looking for can't be found on scannerdrivers.com.
