Only now with the ScanSnap it really works. He simply pulls a everything from the smallest document (inserting a bit fuddelig) until DinA3 (with auxiliary leaf) just anything goes. And the whole thing in sensational speed and ... wireless! That part is awesome and worth every penny. Even with mobile devices (iPhone, iPad) can be scanned.
If something stuck times remains in the catchment, the mostly my own fault (brackets not removed) is. If the device actually for once even a feed error, it indicates an out in perfect manner and allows resume exactly where it left off.
Professionally, I am using Windows 7, a privately Macbook Air: with two works of outstanding scanner. The only drawback so far really is the scanner for WLAN can only be always connected to a computer. If one wants to scan to another computer wireless, you must first register the other computer. This also works again relatively easily.
A strong buy recommendation: the best 400 I've long been invested.
