I picked up the Epson 2480 when it came out; kind of an earlier version of the 3590. It's fantastic for large volume home-quality photo archiving, but wasn't up to scale for "professional" scans; film, print, or otherwise. I don't know if the 3590 has improved much, but a few tidbits of advice:
- I had a lot of photos of varying sizes; even slightly varying, as if from different photo labs, but the same "size". A stack needs to pretty much be exactly the same width or the feeder gets confused.
- Keeping the stack in the feeder filled is important. It would be nice if they could increase the capacity, but generally I was feeding 20-30 photos every, well, 15-20 minutes, or longer on higher quality scans.
- I improved the quality of scans much better by simply wiping off each print with a lint-free cloth before scanning than I did by changing any settings on the scanner. In fact, the default "Home" mode on Epson's software was very good. Other than removing dust, wiping the photos makes sure none of the photos are stuck together, which makes things go much more smoothly.
Really, tho, great products -- HP had come out with something similar a year or so before the 2480; I forget the product, but it had trouble with scratching the photos that scanned through it. Ouchie. The Epson didn't cause any such trouble.
Enjoy the scanning!
