Re: filmscanners: My replacement 8000 is banding like the first one :-(

Actually, Nikon LS2000 and LS30 and I suspect all the newer 35mm
models, at least, move the scanning "unit" (CCD, lens and lighting
source and any mirrors), and not the film.

Yes, they move the film into frame position, but then the fine movement
is done by  moving the scanner "head".

This does probably allow for more accurate scans in multi-pass
situations.

Probably the best manner for multi passes, is when the scanner allows
for each "line" to be multi-scanned without moving anything... scan,
scan, scan, scan, move, scan, scan, scan, scan, move... you get the
idea, building up all the multiple copies at the same time.  Then they
are all in identical registration.
