An apparatus for registering film in a drum scanner assembly comprising: a horizontally oriented concave curved film platen having first and second horizontal edge regions and third and fourth curved side edge regions connected between first and second edge regions, the concave, curved film platen having a curved surface defining a curved film path from the first edge region to the second edge region; a plurality of slider assemblies having film engagement members mounted relative to the platen to engage film fed into the film platen, the film engagement members being independently slidable within the slider assemblies; and means for simultaneously moving the slider assemblies according to the size of film to be fed onto the film platen such that all of the film engagement members are aligned across the platen in a direction perpendicular to the film path; wherein as film is fed onto the film platen from the first edge region along the curved film path toward the second edge region, the leading edge of the film engages the film engagement members to move the members along the slider assemblies until the film is registered on the platen, the film being de-skewed during the movement.
