Abstract: An apparatus for processing photosensitive material. The apparatus includes a processing chamber having an entrance and an exit for allowing a photosensitive material to travel through the processing chamber. A first supply means is provided for supplying processing fluid to the processing chamber to create a first fluid layer on one side of the photosensitive material and a first drain for removing processing fluid from the first fluid layer. A second supply means is provided for supplying processing fluid to the processing chamber to create a second fluid layer on the opposite side of the photosensitive material and a second drain for removing processing fluid from the second fluid layer. Means are provided for minimizing oxidation of the processing solution.

Abstract: A method for replenishing a solution in a film processor having a sump tank. The method provides for adding a sufficient amount of replenishment solution to the sump tank upon powering up of the film processor and in response to removing processing fluid from the sump tank and supplying it to the processor so as to raise the level of the processing fluid in the sump tank to a predetermined level. The addition of further replenishment solution is delayed until a predetermined amount of photosensitive material has been processed through the film processor. Thereafter replenishment solution is supplied to the sump tank in accordance with the amount of film that has been processed by the film processor.
