  There is a new version of the microtek2 backend in the CVS-Snapshot
  which is available at www.mostang.com/sane. I don't know if it helps but
  if you like you can test it.

  It depends on the bug in the firmware, i think you will have to find it
  out by yourself.

  You should modify the backend so that it corrects the values rather than
  xsane. Xsane is identical for all scanners, the scanner-dependent code
  is in the backend (microtek2.c in your case).
