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 fixed time interval is initiated after which the anti-oxidation replenishment required due to expired time is compared to the amount of anti-oxidation replenishment provided by the exhaustion replenishment in that time interval. An amount of needed anti-oxidation replenishment is added to the developer tank, as a function of the difference by which the required anti-oxidation replenishment exceeds the anti-oxidation provided by exhaustion replenishment. If the accumulated amount of replenishment exceeds the anti-oxidation replenishment needed, no replenishment is provided and the excess value is carried over to a subsequent time interval so that the accumulated overreplenishment errors which occurred in prior art fixed time/variable quantity replenishment systems are eliminated.
