Abstract

An electrophotographic printing or copying machine includes a functional module which can be readily removed and replaced. 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. In a remanufacturing process, certain combinations of codes in the memory are noted to determine whether individual parts in the module should be replaced.
