An electrostatographic type copying or reproduction machine incorporating a programmable digital computer to operate various machine components. The computer includes a memory which contains a plurality of different operating programs with each program instructing the machine to operate in a different manner. In one embodiment, one of the programs is utilized to produce copies, whereas other selectively accessable programs operate the machine components in such manner to diagnose machine malfunctions.

Reproduction machine with different operating programs

A reproduction machine for making either single sided or duplex copies, and incorporating automatic document handler and sorter for handling original documents being copied and copies made. To enable copy quality to be checked, either when the machine is stopped or in the midst of a copy run, a sample copy is provided for. Where the sample copy is selected during a copy run, an accommodation in copy billing rate is made.

Sample copy system for xerographic reproduction machine

A reproduction machine for making two-sided or duplex copies. When there is an odd number of simplex original documents to be copied in the duplex mode, the last copy sheet bears an image only on one side. The present invention provides a control system for operating various machine components in response to such an occurrence in order to optimize the throughput capability of the machine.

Automatic duplex control system for a reproduction machine

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.
