An electrostatographic type copying or reproduction machine incorporating a programmable controller to operate the various machine components in an integrated manner to produce copies is disclosed herein. The controller carries a master program varying machine operating parameters from which an operating program for the specific copy run desired is formed and used to operate the machine components to produce the copies programmed. As an aide to maintain copy quality and machine reliability, the programmable controller includes diagnostic programs for operating the machine components in a different manner. The machine includes a plurality of sensors disposed along the paper path through which sheets of paper are transported to various locations in the machine. As each sheet is detected, the time on a counter is stored in the controller memory. One of the diagnostic programs is utilized to selectively access the times as desired. |
