    There is a new version of the microtek2 backend in the CVS-Snapshot
    which is available at 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).
