   I've got an Epson Perfection 1670 Photo and I'd be glad to answer any
questions you (or anyone else on this mailing list) have. Please Cc me as
I haven't subscribed to this list.

- Works under both Linux's scanner kernel module and libusb.
- I've gotten it to work under both Debian unstable (very easy, glorious
  apt-get) and Red Hat 9.0 (heavily mangled with alien-converted debs).
- I was also able to get the Epson firmware file using unshield (CVS
  version from the synce project). Else, you can get it from:
- Flatbed scanning (ie not transparency) works even up to the maximum
  resolution of 1600dpi. Jeff's result (above) maybe caused by the older
  sane-backend-1.0.13 -- shrugs.
- The transparency scanning works to the extent that the fluorescence
  light can be controlled from sane.

- A bit expensive IMHO.
- The four scanner buttons doesn't have any effect.
- Film scanning seems to introduce fine lines (only noticeable at high
  resolutions) that isn't due to the negative.
- Not sure which component is at fault, but the colour of the
  film/negatives aren't properly calibrated.

As far as I'm concerned, film scanning of the 1670 isn't usable under
sane. Of course, it is distinctly possible that I haven't got things setup
correctly as I've never played with film (35mm Kodak) scanning before. It
is also possible that the CVS version of sane-backend fixes some of the
above problems (currently using 1.0.14).

BTW, thank you to the developers who integrated 1670 support into sane.
