Hi !<br>

O.k. - could you send me the exact model of your scanner ? /proc/scsi/scsi<br>
|
|
should do, and maybe the output from SANE_DEBUG_MUSTEK=255 from a color scan.<br>
|
|
<p>
|
|
In case you have one that is identifying itself as MFS12000SP with a firmware<br>
|
|
revision of 1.00, I have a fix for this. I already sent it to David.<br>
|
|
<p>
|
|
The problem is, that this scanner uses a backlog-type line distance correction,<br>
|
|
which had a very subtle bug that shows up at high resolutions and big scan <br>
|
|
areas.<br>
|
|
<p>
|
|
Try scanning a medium sized area at 50dpi. You should not have problems, then. <br>
|
|
Actually you shouldn't have problems at below 72 dpi anyway. <br>
|
|
If you go beyond that, chances are that you will get horizontal stripes.<br>
|
|
<p>
|
|
In case that does not fit your problem, please have a look at sane-mustek(1),<br>
|
|
which discribes two options for mustek.conf that might help you. Well actually<br>
|
|
one of them might help. The lineart fix isn't really helpful for you.<br>
|
|
<p>
|
