A fuser is a component in laser printers that heats the toner powder, causing it to melt and adhere to the paper to create a permanent print.
The fuser unit comprises two parts: a heat roller and a pressure roller.
After the toner is placed onto the paper, it passes through these two rollers.
Under high temperature and pressure, the toner becomes part of the paper.
It is a critical component in ensuring high-quality, durable print output.
