Epson ff-680 vs ff-640

UPDATE: See the updated video at • Epson ff-680 vs ff-640... . Epson has resolved two of the problems with the 680 with driver and software updates. I’ve also found a way to get some better scan quality by disabling one feature when scanning.

l don’t believe Epson is making this scanner anymore so when they’re gone, the ff-680 will be the only option (and in my opinion not as good but still useful and fast if you can’t get the 640, to see why watch the video). If you can’t get the 640 or want the 680, here’s the link: amzn.to/2ZFJDfp
