  • Offset preventing oil pressure sensor system
    Patent number: 6243557
    Abstract: A mechanism for sensing the pressure in the offset preventing oil delivery system for the fuser assembly of a reproduction apparatus. The pressure sensing mechanism includes a pressure-sensing gauge operatively associated with the offset preventing oil delivery system. A pressure sensing circuit includes a pressure gauge port for converting detected pressure from the pressure-sensing gauge into a corresponding electrical signal. Responsive to the electrical signal, the pressure sensing circuit calculates a delta voltage between when the oil delivery system is operating and when the oil delivery system is not operating, and determines whether the delta voltage system is within a specific operating range. A logic and control unit, responsive to the electrical signal, monitors the electrical signal from the pressure sensing circuit to ensure that the offset preventing oil is being properly delivered to the oil delivery system.
