Abstract
Apparatus for processing photosensitive material includes upper and lower tanks for a processing solution. The tanks are connected together so that the solution can flow freely from the lower tank to the upper tank. The photosensitive material is advanced through a processing chamber between the tanks while the solution in the upper and lower tanks is provided to the chamber. A sump holds a supply of the processing solution, and a pump is coupled to the sump to draw the solution from the sump. The pump also is connected to the lower tank so that the processing solution is delivered to the lower tank, and from the lower tank some of the solution is furnished to the upper tank.
