Abstract
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. The controller carries a master program bearing 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. A multiple prioritized interrupt system is employed to distribute the operating program to the machine. Self check routines check the operational integrity of the controller prior to start-up of the machine and periodically while the machine is processing copies.
