ABSTRACT:
In a roller transport assembly of a film processor, respective cross-over rollers for transferring the exposed film from one tank of processing solution to an adjacent tank of processing solution are positioned above the free surfaces of the solutions during normal operation. However, the cross-over rollers are immersed in the solutions during non-operation of the processor to prevent the residue of solution on the roller surfaces from oxidizing to form a viscous or solid deposit.
