ABSTRACT:
Electrophotographic copying apparatus is disclosed having an elongated electrosensitive web defining a plurality of selectable image areas and having a plurality of perforations formed along an edge therein and movable along an endless path relative to a plurality of actuable work stations disposed along the path. The work stations are operative when actuated to perform a work operation on a selected image area of the web, respectively. The apparatus includes means disposed at a fixed location along the path for sensing the perforations to produce signals, a logic and control unit having a programmable computer with a stored program and responsive to such perforation signals for actuating the work stations in accordance with the program to cause the work stations to perform work operations on the web in timed relation to movement of selected image areas along the path respectively.
