dirt from the rollers with while turning the toothed wheel slowly in either direction. Dry the rollers

The roller frame should not be removed from the adapter. When opening the roller frame, stop when
you feel resistance. Forcing the frame open could result in damage to the adapter.
If the rollers inside the adapter are not clean, even film that is neither curled nor warped may jam in the
adapter several times in succession, possibly resulting in damage to the film. Should this occur, you will
need to clean the rollers. If the film continues to jam after the rollers have been cleaned, consult with
your nearest Nikon service representative.
