The invention relates to a processor for photographic material comprising a large number of processing tanks (1-9), through which the photographic material to be processed passes in sequence and in which photographic processing solutions, such as in particular, developer, bleach, fix and stabiliser solutions are provided. The processor also comprises a pump and conduit system for pumping the processing solutions that are used from storage containers for the processing solutions and water from a water tank into the processing tanks. A replenishment pump (41-47) and a corresponding replenishment conduit (31-37) are provided for each storage container (11-16) and the water tank (24). A control unit (50) for the replenishment pumps interacts with the level sensors (S1-S6) that are allocated to the storage containers, in such a way that the replenishment process is stopped when one of the storage containers is empty. An additional pump (71-73) and a corresponding additional conduit (61-63), which are controlled by the control unit (50), are provided at least for each of the storage containers that hold the photographic developer solution (11-13). Said pump and conduit can be used to automatically pump residual quantities of the processing solutions held in these storage containers (11-13) out of said containers. All remaining storage containers can be emptied, leaving no residue, using the replenishment pumps (74-76). The automatic emptying of the storage containers without residue simplifies the treatment of said storage containers and in particular, simplifies their disposal, thus making the latter less expensive. |
