Heat belt (belt fuser)
The heat belt is a thin metal belt with a coated surface. This belt is heated by a ceramic heater bar. The heat is applied
to the media passing between the heat belt and pressure roll, fusing the toner on the media.
Heat belt (hot roll fuser)
The heat roll is a hollow metal tube with a coated surface. This tube is heated by a halogen lamp. The heat is applied
to the media passing between the heat roll and pressure roll, fusing the toner on the media.
Pressure roll
The pressure roll is used to apply pressure to the media surface for fusing. Pressure is applied to the media between
the pressure roll and heat roll (or heat belt) to aid in the fusing process.
Heater lamp (hot roll fuser)
The heater lamp is a quartz glass tube containing a halogen heater coil. A terminal is mounted to the end of the heater
rod using a harness.
Thermistor
The thermistor monitors the surface temperature of the media-feed portion of the heat belt or heat roll to provide
feedback to the controller board. This information is used to turn the ceramic heater or halogen lamp on and off to
maintain the desired temperature.
