Abstract
An automatic photographic paper cutter cuts photographic prints from a strip of photographic paper which bears cut marks indicating the locations of desired paper cuts. An automatic paper feed control allows a predetermined number of cut marks to be missing without halting the operation of the paper cutter. A total feed length for the last previous paper feed-and-cut cycle in which cut marks were sensed at both ends of the cycle is stored and continuously updated with each paper feed-and-cut cycle. If a cut mark is not sensed within a predetermined length or 'window', the automatic paper feed control causes the paper to be driven the stored total feed length, stopped, and cut.
