Abstract: An automatic photographic processor having a filter provided in a circulating flow path of the processing liquid used in a developing tank. A control device calculates the total quantity of light-sensitive material processed by the liquid since the filter was last changed. The control device generates a warning signal when the total quantity reaches a predetermined value. An accoustical or optical warning device responsive to the warning signal indicates that the filter should be changed. A flowrate meter or pressure detection system in the circulating flow path checks the effectiveness of the filter and can also generate a warning signal for the warning device to indicate that the filter should be changed.
