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.
