Abstract
A multiprocess photographic processor has a plurality of tanks through which photosensitive material is transported. Different photosensitive materials are transported through different combinations of the tanks to provide different processing while utilizing the same processor. An automatic replenishment control system stores replenishment rates for each type of photosensitive material, as well as pattern information indicating those tanks which require replenishment during a particular process. During the processing of photosensitive material, replenishment is provided to selected tanks based upon the type of photosensitive material being processed, the stored replenishment rates, and the stored pattern information associated with the particular process being used.
