It's for the 4490, but maybe the 3490 has the same problem?

Thank you for the link.
Hi,
I am wondering whether the epkowa backend is capable of 16 bits/channel,
as I only get a funny stripy false colour preview at this depth.
Scanning at 8 bpp is OK, but the 16 bpp options seems valid also in the
sense the backend accepts it.
I own an Epson Perfection 3490 Photo, which, by the

Really? Then that would be an improvement as compared to the Windows

Hi Krzysztof,
Did you manage to patch the snapscan backend in order to get full bit
depth raw (uncorrected) data from your scanner? I'm interested also but
have very limited C skills.

It looks like the black calibration (lower values, around 70) is the same
data in both 8-bit and 16-bit mode (i.e., in 8-bit mode the LSB is
present and 6-bit MSB is assumed to be zero).
I will experiment with this a bit longer -

Do you know whether this scanner sets a different focal plane when
scanning slides/film compared to the flatbed (as it should)?
Haven't checked that yet. But I don't know if the

Hi,
Is there anything I can do to help get the Transparency unit to
work?
As far as I know the transparency unit of the 3490 works ok. The only
thing not supported is the automatic film feeder of the 3590. Please
make sure you

otherwise it would be nice to know if quality calibration solves it,

I own an Epson Perfection 3490 and I am beginning to use it with the CVS
version of SANE (snapscan backend). While it seems to work well at
resolutions up to 1200 dpi (but I did not yet perform really thorough
testing), I noticed a kind of interlacing behaviour when scanning
negatives/diapositives

You should make sure that the epkowa backend is installed in the same
location as the other sane-backends. Most likely, you can fix things

What is the normal procedure to set-up the latest Iscan with Debian? I
did so far:
- download the tar.gz
- unzip, detar, configure and compile
- make install
- copy epkowa.desc into the dll directory
- modify dll.conf to include epkowa
I noticed files intended for hotplug in the source tree.
Which current USB, =3200 dpi scanners able to scan films/slides are
well supported by SANE (or by other, possibly proprietary but freely
available frontends)? I know of Epson PF 3490 and 3590 which work more
or less according to recent posts, but how about other types/brands?

Hi all,
I have to apologize for putting a corrupt file on my homepage.
In the file microtek2_20010814.tar.gz there was missing a part of

Now I have the correct version up. Please try again.
