Abstract
An electrophotographic printing or copying machine includes a functional module which can be readily removed and replaced by service personnel. The module includes a monitor in the form of an electronically-readable memory, which includes information about how the particular module is to be operated. A distribution board electronically accesses the memories within the monitors and reads therefrom information, such as how much voltage to supply to different components within each module. The distribution board can also update the number of prints made with each module, and maintain this count within the monitors.
