There are three heating lamps inside the heating roller of the fusing unit, and one lamp inside the pressure roller for a total of four lamps.
- The heating roller has three fusing lamps (1020W each). The heat of this roller is transferred directly to the fusing belt.
- The pressure roller contains one fusing lamp (800W). The lamp inside the pressure roller keeps the pressure roller heated while the machine is in standby mode waiting for the next job.
- The heating elements are switched on an off at varied intervals for different paper sizes.
- The heating roller has four heat pipes on its inner surface. This comprises a closed condenser system that keeps the heat evenly spread over the surface of the heating roller.
