Hello....<br>

<i>&gt; Hi !</i><br>
<i>&gt; </i><br>
<i>&gt; &gt; My problem is that using a mustek 1200SP scsi scanner with sane,</i><br>
<i>&gt; &gt; gray images work at any resolution without any problems. If I try</i><br>
<i>&gt; &gt; to scan colour, the image comes out totally scrambled (the colors</i><br>
<i>&gt; &gt; are really weird, stripes all over the image, etc).</i><br>
<i>&gt; </i><br>
<i>&gt; O.k. - could you send me the exact model of your scanner ? /proc/scsi/scsi</i><br>
<i>&gt; should do, and maybe the output from SANE_DEBUG_MUSTEK=255 from a color scan.</i><br>
<p>
Since the machine is at home, I cannot send the exact<br>
/proc/scsi/scsi now. But the Scanner identifies itself as SCANNER<br>
in /proc/scsi/scsi (where normally the brand stands).<br>
<p>
<i>&gt; In case you have one that is identifying itself as MFS12000SP with a firmware</i><br>
<i>&gt; revision of 1.00, I have a fix for this. I already sent it to David.</i><br>
<p>
yes, could be. think that's it.<br>
<p>
<i>&gt; The problem is, that this scanner uses a backlog-type line distance correction,</i><br>
<i>&gt; which had a very subtle bug that shows up at high resolutions and big scan </i><br>
<i>&gt; areas.</i><br>
<i>&gt;</i><br>
<i>&gt; Try scanning a medium sized area at 50dpi. You should not have problems, then. </i><br>
<i>&gt; Actually you shouldn't have problems at below 72 dpi anyway. </i><br>
<i>&gt; If you go beyond that, chances are that you will get horizontal stripes.</i><br>
<p>
correct. I've testet it, till 72 dpi it works without any<br>
problems. Also the Preview is fine.<br>
<p>
<i>&gt; In case that does not fit your problem, please have a look at sane-mustek(1),</i><br>
<i>&gt; which discribes two options for mustek.conf that might help you. Well actually</i><br>
<i>&gt; one of them might help. The lineart fix isn't really helpful for you.</i><br>
<p>
<p>
If you could send me the fix, I would test it tonight....<br>
<p>
Thx in advance<br>
Tobias<br>
