Fuser Unit
A heated component that bonds toner to paper using heat and pressure during the printing process.
Detailed Explanation
The fuser unit is a critical component in laser printers and copiers. It uses heat (typically 180-220°C) and pressure to permanently bond toner particles to paper. The fuser consists of a heated roller and a pressure roller that the paper passes between. Fuser units require periodic replacement (typically every 100,000-300,000 pages) and are a significant maintenance expense.
