ABSTRACT:
Processing solutions in a film processor for sheet film, for example, are replenished on the basis of the number of sheets processed during a predetermined time period. A first volume of replenishment solution is added to a tank for the processing solution each time a sheet is processed until a first predetermined number of sheets has been processed. If the number of sheets processed during the time period exceeds the predetermined number, then a smaller volume of replenishment solution is added to the tank.
