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.

System for managing replaceable modules in a digital printing apparatus

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.

Remanufacturing system for replaceable modules in a digital printing apparatus

A fuser module, being a fuser subsystem installable in a xerographic printing apparatus, includes an electronically-readable memory permanently associated therewith. The control system of the printing apparatus reads out codes from the electronically-readable memory at install to obtain parameters for operating the module, such as maximum web use, voltage and temperature requirements, and thermistor calibration parameters.

A shaft assembly and method of forming a shaft assembly having an elongated hollow shaft with a stepped portion on the surface of the shaft. The stepped portion of the shaft surface is formed of two straight edge sections joined by an inclined section. A gear having a corresponding straight/inclined edge configuration engages the shaft and contacts the shaft only on the corresponding straight edge portions. Both the shaft and gear are made of plastic.
