What version of the backend do you use ? The one included in sane-1.00
should not show this behaviour. A pre-0.6 version of the backend exists,
for which some people have reported problems, that look like yours.

The scanner (and the backend) support scans with a color depth of more
than 8 bit per color, but scanimage (and xscanimage, and most
image processing programs) don't.

If the scanhead moves back and fourth during a scan, you might consider
to increase the 'option strip-height' in the microtek2.conf file. Otherwise
it's probably not a problem of sane or the backend.
