BEWARE of using this if you are trying to scan to PDF especially if you use PaperPort software. The pdfs show up with a documate watermark on them indicating that it is a trial version. GOOD LUCK getting it off...tried the ScanSoft support they know it is an issue but their fix doesnt work and youll have to pay $40 if you want to talk to someone. Still have not figured this out. Also, pages scan at 25pp per minute once they start going through the wait time at the start is long (even if you dont use the energy saving mode). http://garyadair.com/324971
