What's the General Structure of Toner Cartridges?

- Jul 04, 2018 -


It is generally composed of a basic substrate made of aluminum, a toner cartridge fitting, and a photosensitive material coated on the substrate. According to the difference of photosensitive materials, there are basically three types: OPC drum (organic photoconductive material), toner cartridge (Se selenium) and ceramic drum (a-si ceramic).


From the perspective of life, the life of the OPC drum is short, generally only about 3,000 pages, of course, the price is also the cheapest.


The life of the Se drum is about 9000 pages, and the life of the a-si drum can reach 90,000 pages. The price is naturally increased by analogy.


In terms of composition, the general OPC drum has only three layers. The first layer is an aluminum tube, the second layer is an insulating layer, and the third layer is a photosensitive layer. The surface of the toner cartridge (Se selenium) and ceramic drum (a-si ceramic) is synthesized from four to five layers. In particular, the ceramic drum, the fourth layer is the first protective layer, the fifth layer is the second protective layer, and the fourth and fifth layers are used to protect the photosensitive layer, thereby ensuring the long life of the toner cartridge.
