Hi GT93769,
Thank you for using the Xerox forum.
I checked on the Xerox Scanners support site and noticed that when I select Documate 3220 There are TWAIN downloads available.
Have you reviewed this site and drivers? > Office Products> Scanners> DM3220 TWAIN Drivers
I would suggest that you review the DM3220 TWAIN Drivers and respond or you may consider contacting our specific product support experts at the following link: Request more information from a Solutions Advisor
