I wondered about the “Dust Removal” too, but I gave it a shot and the result was far from what I was getting with Digital ICE. There was still quite a bit of dust and some strange artifacts as well. So I assume it’s the same “Dust Removal” as in the previous version.
To download Epson Scan 2, you have to go to the Support section of Epson’s website and enter your scanner model there.
You’ll find the download link below the “Drivers”, it’s called “Scanner Driver and Epson Scan 2 Utility v6.4.84”. Here’s a link to the support page for Epson V600.
