Abstract: This provides an electrophotographic system having heat rollers that have roughened surfaces capable of cleaning debris from the surface of the fuser roll. This debris can be removed from the system by paper in subsequent contact with the fuser roll containing residual debris.

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.
