Try to scan a narrow strip at 1200dpi (e.g. -x50)<br>
If the problem does NOT appear then it is probably a<br>
problem with the SCSI-Interface.<br>
<p>
The scanner suffers from buffer overrun at high data<br>
rates. I experienced this problem with the SCSI card<br>
shipped with the scanner and (less worse) with<br>
my Adaptec AVA-1505. <br>
<p>
Resolutions &gt;300 dpi are extremly demanding as they<br>
are actually mapped to 600dpi or 1200dpi<br>
(the scanners firmware can't deal correctly with "odd"<br>
resolutions in color mode) and downscaled by the<br>
backend.<br>
