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.
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.
