That's interesting...I thought the Polaroid SprintScan 4k that I had used
the plastic teeth in the carrier to move the film...but you are saying it
only positions the film with those teeth, I assume then locks the carrier
somehow, and uses an other mechanism (lead screw perhaps) to move the film
during scanning.
