Abstract (en)
[origin: WO9716771A1] The invention relates to a unified bus system (CANBUS) used for communication in printing or copying apparatus. Each functional unit of the device is connected to the bus system (CANBUS) by an interface. This interface preferably contains a memory unit (DPRAM) in which data and messages associated with particular functional units or sensors are stored at a defined point. When these data or messages (D1..Dn) are modified, they are updated in all memory units (DPRAM). The functional units (SUB1..SUBn) are notified about the presence of new data or messages (D1..Dn) on demand.
