ABSTRACT:
A processor of photosensitive material includes an automatic control system for providing anti-oxidation replenishment. The control system includes a real time clock for providing an indication of the time of day, and means for storing a schedule of operating hours of the processor. The control system controls anti-oxidation replenishment as a function of the time of day and the schedule of operation. In one embodiment, the control system provides anti-oxidation replenishment on a twenty-four hour basis (even during nonoperating hours) by operating the developer circulation pump and the anti-oxidation replenishment pump on a periodic basis during nonoperating hours. In another embodiment, which is particularly useful when there are restrictions against leaving on electric power to the processor during nonoperating hours, the control system adds a bulk amount of anti-oxidation replenishment at the time of turn-on of the processor. This bulk amount of anti-oxidation replenishment is a function of the time of turn-on and the last turn-off time. Anti-oxidation replenishment is supplied at a first rate for operating time of the processor, and at a second, lower rate for nonoperating time of the processor.
