Abstract:
A replaceable electrophotographic marking engine for use in a marking machine, the replaceable electrophotographic marking engine responsive to control signals for selectively depositing marking material on media, the replaceable electrophotographic marking engine comprising:a housing associated with the replaceable electrophotographic marking engine, the housing configured for docking with the marking machine, the housing having an undocked position and a docked position wherein the housing is secured to a receiving station associated with the marking machine; and a radio frequency linking device mounted to the housing so that the radio frequency linking device is at a specific fixed orientation, and there is substantially no relative movement between the radio frequency linking device and a corresponding radio frequency linking device associated with the receiving station when the replaceable electrophotographic marking engine is in the docked position with the marking machine and the marking material is being deposited on the media, the radio frequency linking device providing a radio frequency link with the corresponding radio frequency linking device for transferring information between the replaceable electrophotographic marking engine and the marking machine without use of electrical conductors directly connecting the replaceable electrophotographic marking engine and the marking machine; wherein the radio frequency linking device includes a signal terminal coupled to a power conditioner, and wherein a supply voltage is provided to components of the radio frequency linking device by the power conditioner as a result of a radio frequency signal at the signal terminal of the radio frequency linking device.
