Abstract
A processor for photographic film or paper has a tank for holding a processing solution. A filter is located within the tank, and solution is removed from the tank through the filter and returned to the tank. An improved replenishment system for the processing solution includes a storage container for holding a concentrated replenishment solution. A pump delivers to the core of the filter a quantity of the concentrated replenishment solution. Water is provided to the filter core through a pressure regulator, a control valve and a fixed orifice. A microprocessor controls the pump and the control valve so that predetermined quantities of replenishment solution and water are simultaneously provided to the filter.
