I never had the 8000 open so I wonder how the film carrier moves
while it scans. It can't be by the gearing teeth at the side of
the carrier one would think. Is there a more sophisticated
mechanism inside ?

I always thought that by the gearing teeth at the side the
carrier is pulled in and positioned and after that a scan unit
moves below the single frame to scan it. Never paid attention to
what it actually does.
