Abstract
There are provided a method, system, and apparatus for automatically cleaning a spread roller system for use in a photographic apparatus of the self-developing type. A cleaning apparatus includes a pod of cleaning fluid rupturable as it passes through a nip of a pair of spread rollers. The cleaning apparatus includes at least an opening which distributes the cleaning fluid over the rollers following pod rupture as the apparatus passes through the nip. Such an apparatus can be included in a film assemblage which comprises a film cassette housing a stack of film units of the self-developable type, wherein the cleaning apparatus is at the top of the stack and is opaque so as to also serve as a dark slide.
