Both good questions and observations.  Frankly, the 
mechanics of the LS-8000 leave me wondering and, 
well, a bit nervous.

If you look very closely you'll see that it is indeed 
that big massive film holder that's being moved 
during the scan.

I too have observed those big gear-teeth on the 
side (edge) of the film holder and wondered about 
their purpose.

Is it possible that the gear teeth are used during 
loading/unloading of the carrier only?

Is it possible that the gear teeth are in any way 
related to the banding?  (The spacing of the gear 
teeth and the spacing of the bands is quite 
different.)
