The error message means that there is an invalid field in
one of the SCSI commands. To tell you more please enable
debugging (set SANE_DEBUG_MICROTEK2 to 30) and set
'option dump 2' in the microtek2.conf file. The latter option
will print all the SCSI commands to stderr.

You could also try different settings (for the scan area size
or the resolution, for example) and tell me, whether these
will allow you to do a scan.

There is nothing unusual in the scanner attributes, so such
an error should not occur. But interesting enough: Your device
claims to have a lookup table size of 4096 words, which means
that it accepts gamma tables. Lee's scanner doesn't accept
gamma tables at all, and it prints the line

LUT capabilities: None

There is now some stuff in the backend, so that it avoids
sending gamma tables to these models. Maybe that your problem
is related to this.
