Summary: This is a screaming fast scanner. Sheet fed scanners are great for 1 purpose, scanning sheets, not thick stuff, not a multi-sized stack of stuff, and not slippery stuff! Great for sales people, mortgage brokers, real estate companies and so forth. There are Vista 32 and 64 bit drivers on Xerox's site.
Summary: I haven't used this scanner extensively yet. I am scanning old paper records. Sometimes two sheets get through at the same time. This may be a problem with other types of scanners as well-I have no experience with other sheet fed scanners. It seems to scan fast, and the Papersoft software seems to work well so far. It is unable to scan photos (with thick paper)-the photo will go off course and jam. This seems to be a major flaw.
