The function and usage principle of printer fuser unit

The main function of the printer fuser unit is to fix the toner or toner covered on the paper to the paper during the printing process, making it a permanent text or pattern. This process usually occurs at the end of the printing process and is called the fusing process.

The printers we operate include common types on the market, such as Xerox, OKI, Lexmark, HP, etc.

The working principle of the fuser unit is mainly based on the two key factors of heating and pressure. Specifically, it generates high temperature through a heating component, and then passes the paper through the slit between the upper and lower rollers at high temperature and high pressure. In this process, toner or toner is heated to its melting point and then penetrates into the fibers of the paper, thereby fusing it.

Currently, TOHITA most popular fuser units include the HP P3015, Xerox B400 and B7025, Kyocera FK-171, and Samsung 3310.

Of course, there are many other popular products that are not on the list.

Depending on the printer model and design, the fuser unit may have some different structures and working methods. For example, some fuser unit may use ceramic plate heaters, while others may use electromagnetic induction heaters. In addition, in order to ensure the fusing unit effect and prevent overheating, the fuser unit is usually equipped with devices such as heat-sensitive elements and thermal protectors to sense temperature changes and control the fusing temperature.

In general, the fuser unit is an indispensable part of the printer. Its function is to fix the toner or toner on the paper during the printing process, thereby producing clear and durable text or patterns.
