A processor of photosensitive material includes an automatic control system for providing both developer and fix exhaustion replenishment. As each strip of photosensitive material enters the processor, the width and length of the strip is sensed. Based upon the width and length, a determination of the area of each strip is made. The density of each strip is sensed after processing. Developer exhaustion replenishment and fix exhaustion replenishment are separately controlled. The developer exhaustion replenishment is provided as a function of a product of the area of the strip, the density of the strip, and a stored developer exhaustion rate. Fix exhaustion replenishment is provided as a function of a product of the area of the strip, an inverse of the density of the strip, and a stored fix exhaustion rate. A carryover rate is also stored which is indicative of carryover of developer fluid from the developer tank into the fix tank of the processor. A minimum fix replenishment is determined as a function of a product of the carryover rate and the area of the strip. If the minimum fix replenishment exceeds the fix exhaustion replenishment, the minimum fix replenishment is provided to the fix tank.
