Try to scan a narrow strip at 1200dpi (e.g. -x50)
If the problem does NOT appear then it is probably a
problem with the SCSI-Interface.

The scanner suffers from buffer overrun at high data
rates. I experienced this problem with the SCSI card
shipped with the scanner and (less worse) with
my Adaptec AVA-1505.

Resolutions >300 dpi are extremly demanding as they
are actually mapped to 600dpi or 1200dpi
(the scanners firmware can't deal correctly with "odd"
resolutions in color mode) and downscaled by the
backend.
