Abstract
A processing solution delivery system and method for a photographic processor includes a plurality of chambers that are adapted to hold a distinct processing solution therein. A manifold is fluidly connected to the chambers and includes an inclined solution passageway. The manifold provides a connection between the chambers and an associated processor. Provided in a spaced manner along the inclined solution passageway are manifold bores which introduce solution at different points along the inclined passageway. With the present invention, it is possible to introduce wash solution at the highest point of the inclined processing path at the end of a processing cycle so as to assure the removal of contaminants from previously supplied solutions. Further, it is possible to introduce a bleach or fixing solution at the lowermost point of the inclined path to effectively and uniformly quench a development reaction.
