ABSTRACT:
A photographic reprint system includes a preparation station at which film segments or strips are attached to an elongated tab. Indicia (typically in the form of holes) are formed in the tab to indicate the location of each film frame, to signify the end of the film segment, the end of a customer order, and the end of a reel. Information relating to the printing of each film frame, including the number of holes in the tab adjacent that frame, is stored in a storage medium such as a floppy disk. At a photographic printer, the tab and attached film segments are advanced sequentially to a print gate, where printing occurs based upon the data which is sequentially retrieved from the storage medium. A first hole sensor located upstream of the print gate counts the number of holes in the tab as each frame is advanced to the print gate, and this number is compared with the stored number which has been retrieved from the storage medium. Even if the numbers disagree, however, the film frame is still printed, but the number of holes is also counted by a second hole sensor adjacent the print gate. If the number of holes sensed by the second sensor also disagrees with the stored number, further operation of the printer is inhibited and the operator is required to resynchronize the system. If, on the other hand, the number of holes sensed by the second hole sensor agrees with the stored number, operation of the printer is permitted to continue without interruption.
