An electrostatographic type copying or reproduction machine incorporating a programmable controller to operate the various machine components in an integrated manner to produce copies. 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.

Control system and interface for electrostatographic machines

A xerographic 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 fault flag array is routinely scanned, each flag comprising the array being associated with an operating component or area of such machine such that on a fault or malfunction thereof, the fault flag corresponding thereto is set. On detection of a fault flag, a machine fault is declared. Display means are provided to visually identify the fault location. A permanent record of certain faults and machine operations are stored in memory for future use.
