I have never used Epson's software other than for testing, TWAIN or
not, to drive any Epson scanner. To me, that's just junk software.

I use Vuescan, which supports the Epson Perfection 1640su and works
very well. I've used Vuescan to drive Epson 2450, V700, Minolta Scan
Dual II, Polaroid SprintScan 35E/S and Nikon Coolcan IV ED (LS-40)
scanners. I've compared it against the Epson, Minolta, Nikon, Polaroid
OEM software and a couple of third party (SilverFast, Apple's Image
Capture, and a couple others I can no longer remember). It is without
a doubt the best scanning software I've used.

Here's an information page for Vuescan with this scanner:

You can download Vuescan for evaluation from the home page:

And there's a decent Users Guide available in PDF:

I don't work with a scanner unless Vuescan supports it nowadays.
That's my bottom line. ;-)
