Abstract
Disclosed herein is an automated system adapted to be connected to commercial film processors, the system including a common automated sequencer for advancing the wash, rinsing and fill cycles in both the developer and fixer containers. To accommodate the level requirements in the various containers and the variations in pumping rate there are periodic wait logic sections which bring the developer and fixer cycle into synchronism. The foregoing system includes an interface panel provided with level detectors and the necessary interconnections with the commercial units.
