Your scanner is 2400dpi x 4800dpi? Perhaps the attached patch is more
usable. It reduces the maximum speed of the head, and adjusts the
maximum y-resolution.

These scanners are pretty low-level. To do anything useful, you need to
setup the motor and ccd. This includes calibration. The calibration is
done only once in win98.

These analyses seem to be not very useful. I see a lot of unknowns where
there should be register reads/writes. I put my scripts here:

There shouldn't be a lot of windows logs needed.
