This evening a demo ff680w scanner arrived at my store, so I took it home to test it out against my ff640. If you are thinking of buying this type of device, I strongly advise against buying it. Buy the 640. There are two main reasons
1 Scan quality. Sorry, but side by side the 640 does a better job, especially with images on luster type paper. I’ve attached a file, zoom in to 100% and to me it’s pretty obvious. This is at 300dpi, at 600 dpi the 680 is a little better, but still not as good as the 640. I’m totally puzzled by this, maybe a tradeoff for being slightly faster? Not worth it.
2. In what appears to be a total blunder, I cannot find anyway to scan a stack of snapshots in the order of the stack. On the 640, you stack the pictures face down into the scanner and it takes the bottom one first (which is the first print in the stack), and proceeds. When its finished, you can continue to take prints off of a large stack, place them in the scanner, and continue scanning. When finished, the images are numbered in order from top to bottom of the stack.
With the 680, you stack the prints into the scanner face forward. Just like the 640, it takes the bottom print first and proceeds through the stack. That means the bottom print is now numbered 0001, and the top print is whatever number of prints that were in the stack. So the only way you can keep the sequence correct is to scan from the bottom of the stack forward. Of course, this means the sequence is backwards of the stack, and so you have to figure out some way to reverse the filenames if you want them to make any sense.
One other big issue, one of the 680’s big features is wifi connectivity, but unless your router supports WPS, it’s a nightmare to get the scanner onto your network. Many of the newer devices (Like Eero) do not support WPS. I gave up trying to get it onto the network, and now after testing it glad I didn’t keep trying.
It’s headed back to Epson tomorrow, I wouldn’t sell this device to a customer.
The good news is the new software works just fine on the 640 and is definitely an improvement. Auto rotation detection works at least part of the time, and you can view the results in a browser like fashion right after scanning, correcting rotation without having to go to a secondary program.
