Abstract
To minimize the effects of electromagnetic noise on signals generated by a data processing unit controlling the process stations in an electrostatographic machine, the data processing unit itself is encased in a shielded housing to thwart electromagnetic radiation. Output signals from the data processing unit are distributed to remote interface units located throughout the electrostatographic machine where the signals are stored and used to control networks actuating the electrostatographic process stations. Electro-optic couplers are used in transmitting input and output signals to and from the data processing unit to further minimize noise isolation.
