ABSTRACT:
A device for recycling developer fixer into a photo processing machine. The device includes containers for containing chemicals coming out of overflow outlets of the photo processing machine. The chemicals flow into the container, and a portion thereof are recycled and returned together with fresh chemicals to the processing machine. A portion of the used chemicals are discharged to a drain. The recycled chemicals can either be pumped into an automixer where the fresh chemicals are added or directly into the inlet line to the photo processor tank where fresh chemicals are simultaneously also input. Alternately, the overflow can be directed to the automixer first and either returned directly therefrom, or optionally, by way of a separate container, to the photo processing machine.
