<p>An automatic fluid replenisher control system for processors of photosensitive material stores density aim point values for control strips of photosensitive material, a developer exhaustion replenishment rate, and anti-oxidation replenishment rate. Signals are provided from which the area and the density of the material processed can be determined. The automatic replenisher control system provides exhaustion replenishment as a function of area and density of the processed material and the stored developer exhaustion replenishment rate, and provides anti-oxidation replenishment as a function of the anti-oxidation replenishment rate and the amount of exhaustion replenishment which has been provided. On a periodic basis, a control strip is processed, and densities of a high and a low density area of the control strip are measured. The automatic replenisher control system compares the low density value with one of the density aim point values. Based upon this comparison, the automatic replenishment control system leaves the exhaustion replenishment rate unchanged, adds additional exhaustion replenishment, inhibits exhaustion replenishment for a predetermined time interval, requests an additional control strip after a predetermined time interval, and/or adjusts the stored exhaustion replenishment rate. Once the measured density from the low density area of the control strip is within a selected range of the density aim point value, the automatic replenishment control system compares the difference between the two measured densities of the control strip with the difference between the two density aim point values. Anti-oxidation replenishment is adjusted in a similar manner.</p> |
