Abstract: The invention relates to an office machine that comprises an electronic control unit and a data communication interface, wherein internal data of the office machine can be read via the data communication interface and internal data of the office machine can be input. According to the invention, the office machine (10) is associated with a computer unit (20) that is or can be connected to a computer network (24) and that can access internal data of the office machine. Said computer unit is further adapted to allow read-out of internal data of the office machine via the computer network or/and input of internal data of the office machine via the computer network.

Abstract: A control system for office machines, in particular copiers or the like, includes a replacement component which must be exchanged after a specific level of use, the system includes at least one detector of level-of-service and a display unit for the level of use associated with the detector to display the level of use and/or any crossing of an upper limit of level of use. The control system further includes a read/write unit for a coded data carrier, in particular a magnetic or chip card, associated with each replacement component to be integrated. Upon introduction of a coded data carrier, the control system shall reset the level-of-use detector. Such a control system lowers the danger of qualitatively inadequate replacement components being installed.
