Fuser Units and Parts
Fuser units permanently bond toner to paper using heat and pressure. Our fuser parts include the heated roller/upper fuser roller and pressure roller also known as lower fuser roller, ensuring high-quality, reliable prints.
What Is a Fuser Unit?
A fuser unit is a key component in laser, electrostatic, and xerographic printers. It permanently bonds toner to paper by using two rollers—one heated and one that applies pressure.
Components of a Fuser Unit
-
Heated Roller (Upper Fuser Roller): Heats up to approximately 150° C to 200° C, melting the toner so it can adhere to the paper.
-
Pressure Roller (Lower Fuser Roller): Works with the heated roller to compress the toner into the paper fibers, ensuring a solid print.
Fuser Lifespan
On average, a fuser unit lasts about 100,000 pages, though this may vary depending on your printer’s use and maintenance.
Signs of Fuser Failure
Worn fuser units may cause prints to show parallel spots, loose toner, or stains, indicating that replacement is needed.
