  Yes, this option is not effective for that model. The calibration for
  the 330cx is different from the calibration process on other models.

  Yes, that is a known problem. I will see whether I can fix it in the near
  future. Grayscale and B/W scans, however, should not have this problem.

  This is interesting, because it is the first time, that I read, that
  a scan with this model does not show this strange behaviour (hitting
  the top or bottom of the scan area). The backend does not execute one
  SCSI command for this model, that is executed, when other models are
  connected. This command fails on the 330cx for whatever reason, and
  I suspected that this missing command might cause these problems.
  When the scanhead stops at the right position after a scan under windows
  this shows, that the missing command is probably not the cause.

  These debug options are just fine. Can you make such a trace available,
  from the first scan after the scanner is switched on ? Can you also
  trace a scan (also immediately after the device is powered on) with
  sane ? The 'option dump 2' should be set in the microtek2.conf file.
  This will trace the SCSI commands, that the backend issues, so that we can
  compare them.

  However, there is one drawback of the wine traces. wine traces only the
  SCSI commands, but not the parameters of the commands, and not the
  replies from the device, so I cannot say, whether it will be sufficient.
  Otherwise wine must be patched (I have a patched version of the 990704
  release).

  Bernd
