ABSTRACT:
A system and method for processing a flexible photosensitive sheet or web material (PSM) including a photographic emulsion on at least one of the faces thereof employs a reservoir cell having an elongated cavity for containing a relatively small quantity of processing solution held therein in a sheet-like configuration and through which the PSM is routed during a processing operation. A pump is associated with the cell for circulating processing solution through the cell cavity from one end of the cavity to the other end thereof to enhance the distribution and mixing of the processing solution within the cavity. There is also associated with the cell a flat strip of substantially air-impermeable material for engagably overlying a substantial portion of the upper surface of the processing solution contained within the cavity to reduce the likelihood of oxidation of the solution if left within the cell for a prolonged period of time. The cell also includes an electric heating element secured in heat exchange relationship with the body of the cell and appropriate controls for controlling the temperature of the reservoir and to thereby control the temperature of the processing solution contained within the cell.
