interface is USB Full-Speed (equal to USB 1.1.)
• The USB cable you are using should be the one originally included

scanning speed may vary, depending on the specified scan
settings.

operate on all ISIS (only for Windows) or TWAIN-compatible
applications. For details, contact your application software retailer.
