Abstract
A reproduction machine having a plurality of operating stations and a plurality of devices for controlling operational tasks of said operating stations comprising a master controller having an arithmetic and logic unit for controlling the devices in accordance with sensed operational parameters and a stored operation program and interface means connected in a communication path between the master controller and the devices. The interface means comprises a fiber-optic communication path for isolating the master controller from electrical noise and transients of the devices.
