Hi,
<p>

&gt; Hi ScanMaker users!
&gt;
&gt; Over the last days I've been very busy trying to get my Microtek ScanMaker
&gt; X6 to work with Linux / SANE. I think I've seen about every problem that
&gt; can possibly occur (according to this mailing list...) -- and now it _is_
&gt; actually working. Since I've read nearly every `article' on the list, I
&gt; think it is only fair if I describe the solution which appears to get
&gt; around the problems (at least with my configuration...).
&gt;
&gt; Just for reference, I'm now using
&gt; o the new kernel version 2.2.1,
&gt; o an SCSI adapter AVA-1505 (which came with the scanner),
&gt; o a Microtek Phantom 636 scanner (Microtek says it's actually a ScanMaker X6),
&gt; o the kernel driver aha152x and
&gt; o the SANE package sane-pre1.01-3
&gt;
&gt; First of all, the adapter card should have been PnP (it _was_ detected by isapnp), but this
&gt; approach didn't work; in fact, the situation was exactly the same as Mr Rogers described in
&gt; his article -- see for example
&gt;
&gt; <a href="http://chandra.ph1.uni-koeln.de/linux/lg/issue31/rogers2.html">http://chandra.ph1.uni-koeln.de/linux/lg/issue31/rogers2.html</a>
&gt;
&gt; After the kernel had recognized the card, I tried to use an older version of SANE (which
&gt; came with S.u.S.E. Linux 5.3). Since it had no support for the new Microtek scanners, this
&gt; was doomed to failure...
&gt; Consequently, I upgraded to SANE 1.00; the scanner was now (should now have been?)
&gt; supported, but I just got to the point where it _should_ have started scanning (preview
&gt; scan with xscanimage). Then the whole X server got slowed down and still the scanner
&gt; wouldn't budge...
&gt; Another upgrade to SANE pre1.01-3 produced (after I manually edited part of the makefiles
&gt; to have it find _all_ of my SCSI and JPEG header files) xscanimage started producing
&gt; images, but they all had that greenish tint which is also described in some of the
&gt; `articles' on this list. The strange thing is: the preview scans were OK, just the `real'
&gt; scan was all green (and red -- in fact, only the blue parts appeared to be missing...).
&gt;
&gt; Since I had read about these problems, I then installed on of the `patches' for the
&gt; microtek2 backend, namely the file
&gt;
&gt; microtek2-pre0.6.120399.tar.gz
&gt;
&gt; which produced a more consistent result, i.e. _all_ scans (preview included) got green.
&gt; Installation of the old microtek2 backend from version 1.00 (just the microtek.? files)
&gt; slightly improved the results, but caused one further problem (also described on the
&gt; list): the first scan is OK, all further ones remain green.
&gt; Now comes the good ending: I replaced the microtek2.? files with those from another patch
&gt;
&gt; microtek2-pre0.6.291298.tar.gz
&gt;
&gt; and this combination, strangely enough, is working _and_ produces good color scans (24
&gt; bit), not just one, but as many as I like...
<p>
Sorry for the late response, but the mail mail was delayed until today.
<p>
Since you have read the archive: The problem with the wrong colors is
related to the
"bytes_per_line should be 3 * pixels_per_line, but it isn't" problem.
<p>
Other users have reported exactly the same misbehaviour (wrong colors) for
the version that works for you. I am currently trying to collect a list
of models and FW versions to elaborate the circumstances, under which this
behaviour is shown.
<p>
Thus it would be interesting, which FW version and model code your device has.
<p>
Also, there exists an update of the backend on
<p>
<a href="ftp://ftp.muc.de/people/bernds/mtek2/microtek2-pre0.6.280399.tar.gz">ftp://ftp.muc.de/people/bernds/mtek2/microtek2-pre0.6.280399.tar.gz</a> .
<p>
If you like, you can try it and tell me the results. I would be interested,
if it works for you or if the colors are wrong again.
<p>
In any case: I know now where the problem is and can provide a patch, if
necessary.
<p>
Bernd
