The big upgrade from the ScanSnap s1500 is the ability to scan without a computer. The iX500 has a built-in image processor and wi-fi, you can scan to memory or to a nearby mobile device. And Fujitsu provides its own app, so you don’t have to wrestle with Eye-Fi.
It’s a bit faster, too, at 25 ppm, and you can read about the other upgrades, like multi-feed detection and more-reliable paper-picking on the iX500 product page.
We’ve got a review unit on the way, and we’ll let you know if the iX500 is good enough to keep a ScanSnap at the top of our best scanner picks.
