ABSTRACT:
A low volume photographic material processing apparatus that utilizes a narrow horizontal processing channel with an upturned entrance and exit to contain processing solution within the channel. The channel is formed by a repeating combination of squeegee pinch rollers and impingement slot nozzles. Photographic processing solution is introduced through the impingement slot nozzles and the squeegee pinch rollers are used to remove the processing solution from the photosensitive material and provide transport of the photosensitive material. Solution level control is achieved by drains positioned below the tops of the upturned sections. The slot nozzles and the pinch rollers work interactively to break down the chemical barrier layer.
