Fuser Assembly (Fusing/ Paper Output)
The Fuser Assembly fuses the complete toner image that was transferred onto the paper, using heat
and pressure. The paper output section is also included in the Fuser Assembly. The Fuser Assembly is
made up of the following main components:
• Heat Roller - A tube-covered hollow metal roller, which applies heat to the paper to fuse the toner.
• Pressure Belt - A belt that contains a pressure system within it. This pairs up with the Heat Roller
and applies pressure to the paper to fuse the toner.
• Main Heater Lamp - A Lamp located inside the Heat Roller that heats the left and right ends of
the Heat Roller.
