Abstract
A photographic printer has a paper feed system for automatically advancing print paper by a predetermined feed length after each exposure. A paper feed cut off circuit terminates the paper feed after a predetermined time period in the event that the paper feed has not been previously terminated. This prevents waste of large amounts of print paper in the event of a malfunction in the automatic paper feed system.
