I bought this a few years ago, knowing it had a fault, and intending to fix it, but never got round to it. Basically it is a duplex scanner, so it should scan both sides of a sheet. but the one of the glass lens covers has a crack in it, so you can only use it effectively as a simplex (one-sided scanner).
It should work with Windows PC's and some earler versions of Mac OS, but you will have to download the ScanSnap manager from Fujitsu.
Needs a standard USB 2.0 A-B printer-type cable.
