Fuser film sleeve is a special high-temperature-resistant material film used for fixing when copying or printing by a copier or printer; fixing is the process of fixing the unstable and erasable toner image on the copy paper on the paper, generally through After the fixing unit is heated, the toner is melted, and then penetrates into the deep layer of the paper fiber, which is the effect of copying or printing.

Fuser film sleeve is multi-layered, generally divided into three layers: forming layer, base coating, and surface coating; the surface of Fuser film sleeve is not sticky, and can conduct electricity and heat conduction. A Fuser film sleeve with poor thermal conductivity will not only cause the toner to not be firmly fixed on the media, but also turn the partially softened toner onto the Fuser film sleeve or the lower roller, or even agglomerate, damaging the heating components.
The difference between Fuser film sleeve and fixing roller:
Inside the fixing roller, there are one or two or more heat lamps for heating, so that the characters are fixed on the paper.
There is a ceramic sheet inside the Fuser film sleeve. After the ceramic sheet is heated by electricity, the text is fixed to the paper through the Fuser film sleeve.
Most copiers and printers on the market use fuser rollers, a small part of them use Fuser film sleeves. For example, some Canon printers and copiers use Fuser film sleeves, and all HP printers use Fuser film sleeves. film sleeve.
The biggest difference between the fuser roller and the Fuser film sleeve is that the fuser roller consumes a lot of power, is slow to warm up, has a long warm-up time, and has a long service life. Fuser film sleeve is just the opposite.
