ABSTRACT:
A reproduction apparatus having a series of process stations and a logic and control unit for controlling the operations of the process stations includes a fuser and pressure roller-type fusing apparatus. The fusing apparatus includes a member for oiling the fuser roller, and a fuser skive device with finger portions that contactably ride on the fuser roller for stripping copy sheets. The finger portions are mounted to a flexible member that is connected to strain gauges which sense actual sheet stripping forces on the finger portions. The strain gauges are connected to the logic and control unit which contains a preprogrammed stand for sheet stripping forces on the finger portions on ideal process station conditions. The logic and control unit compares the sensed actual sheet stripping forces from the finger portions for any deviations from such stand, and then use such deviation to adjust an operating condition of at least a process station.
