ROBBY C  I'm using the Epson driver that came with the scanner and have only one issue which is the same as MICKSMAC is having with the SilverFast driver where auto-selecting the multiple frames of the slide or filmstrip holder doesn't work. In '06 when I had a couple thousand slides and negatives to scan, it made for a much longer job than it should have been.

ROBBY C  wrt your second problem scanning multiple images and my 4490 PHOTO with Epson drivers: Except for a short time after buying the scanner, I have not been able to do that either, although I can zoom in on each slide to set the margins. Epson has been more than useless in responding to me about it. I'll never buy another Epson product.
