[filmscanners] RE: Epson Perfection V750-M Pro Scanner,



caryenochr@enochsvision.com,

I apologize for using your post as a vehicle for posting a correction to one
of my earlier posts where I referred to WMA drivers when I should have
referred to WIA drivers.  I am sorry if my error in reference has caused any
confusion or trouble.

Silverfast provides a 64-bit installer for the V500 (and presumably related
Epson
scanners). It's WIA and it installs both a standalone client and a plug-in
for Photoshop.
Silverfast also provides an optional TWAIN version but there's no reason to
install it
that I can see.

In the flier packaged with the scanner, Epson tells you not to install from
the CD. They
point you to their website so you can install the latest 64-bit driver for
it. That
appears to be a WIA driver. Epson's OEM software is like most OEM software;
it's mediocre
and very basic. You need either Vuescan or Silverfast. I use Silverfast
Studio Ai version 6.6.

There's no "yes but." I explicitly stated that I installed a USB scanner so
my comments
applied only to that.

Do any prosumer manufacturers even make SCSI scanners anymore?

I know that. I didn't say they were the same. You might be responding to
someone else's
post there.
