Analysis of the heating principle of the copier: What is the role of the fuser
- Ⅰ. Analysis of the heating principle of the copier
The heating of the copier is to allow the toner or drum of the copier to contact the paper through heat, so that the image can be correctly transferred to the paper. Specifically, the copier melts the toner or toner on the drum by heating so that it can adhere to the paper. The temperature at which the toner melts is generally around 100 degrees Celsius.
So, what are the ways to heat the copier? At present, there are generally two ways to heat the copiers on the market. One is heating through the photosensitive drum, and the other is completed by heating the fuser.
- Ⅱ. What is the role of the fuser in the copier?
The fuser is an important component of the copier. Its main function is to fix the heated toner on the paper. The pressure roller inside the fuser squeezes the paper and toner together so that they can adhere firmly together.
In addition to the fuser, there is another component in the copier called the photosensitive drum. By radiating the photosensitive drum to achieve heating, the static heat on the surface of the photosensitive drum can be printed on the paper, thereby completing the printing.
- III. Summary
To sum up, there are many ways to heat a copier, among which the fuser and the photosensitive drum are important components for heating. The fuser is responsible for fixing the toner on the paper, and the photosensitive drum is heated by electrostatic thermal printing. Regardless of the method, the heating of the copier is to make the printed image on the paper clearer and firmer.
