ABSTRACT:
A processor of photosensitive material includes an automatic control system for providing anti-oxidation replenishment and preventing anti-oxidation overreplenishment, as a function of a stored anti-oxidation replenishment rate and anti-oxidation replenishment provided by exhaustion replenishment. A time interval of a predetermined duration is initiated by the control system. During the interval, the control system provides exhaustion replenishment based upon the area and density of photosensitive material processed. At the end of the interval, the control system compares the anti-oxidation replenishment required due to expired time to the amount of anti-oxidation replenishment provided by the exhaustion replenishment during that time interval. The control system then causes the needed amount of anti-oxidation replenishment to be added to the developer tank. If more anti-oxidation replenishment than needed was provided by the exhaustion replenishment, the control system extends the duration of the succeeding time interval as a function of the excess replenishment.
