Roller frame
Using a dry cotton swab or a swab that has been slightly dampened with water and wrung out,
remove dirt from the rollers while turning the toothed wheel slowly in either direction. Dry the
rollers with a dry cotton swab or leave the roller frame open until the rollers dry.
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.
