ABSTRACT:
A device for preventing a fixing unit from overheating in an electrophotographic system includes a heating lamp positioned within an interior portion of the heat roller for generating heat to increase a temperature exhibited by the heat roller. A frame supports a bearing of the heat roller. A thermal sensor is formed on one side of the frame and contacts a surface of the heat roller to control the temperature exhibited by the heat roller. A thermal fuse interrupts electrical power to the heating lamp upon detecting that the temperature exhibited by the heat roller exceeds a predetermined level. A pressure roller applies a force upon the heat roller so that the heat roller is displaced in a direction towards the thermal fuse as a recording sheet passes between the heat roller and the pressure roller.
