Abstract
An electrophotographic reproduction machine for use as a copier/duplicator having a master microprogrammed controller and a plurality of area controllers cooperatively operative to carry out a plurality of machine operation tasks. At least one of the area controllers contains a separate microprogrammed controller for controlling selected tasks and devices in the reproduction machine in synchronism with the operation of other tasks as controlled by the master controller. An optical communication link couples the master and area controllers and serves to isolate the master controller from transients and a direct I/O connection.
