Abstract
Apparatus for fusing a toner image to a support by means of heat and pressure. The fuser apparatus includes a heated fuser member which contacts toner image carrying supports moved along a path. A sensor is spaced from the fuser member for sensing the temperature thereof and for producing a signal representative of the temperature. Logic and control means connected to the sensor maintains the temperature of the fuser member within predetermined limits and interprets a sudden large drop in the temperature sensed as a jam condition caused by a support deviating from its path of movement and interposing between the fuser member and the temperature sensor.
