ABSTRACT:
A photographic printer has a punch marking module for placing cut and end-of-order marks on the photographic paper. A quick connect/disconnect mounting assembly automatically centers the punch marking module properly with respect to a paper mask. The quick mounting assembly includes a pair of detent bars and registration pins on a mounting base attached to the paper mask. A rigid member and a pair of plate holders form the bottom of the punch marking module. A plurality of ball plungers engage a plurality of recesses in the detent bars and the end plate holders engage side edges of the mounting base. The ball plungers apply a force to the rigid member holding it against the registration pins in an engaging relationship.
