Copier Drum Unit

The basic structure of the drum is generally composed of a basic substrate made of aluminum and a photosensitive material coated on the substrate. According to the different photosensitive materials, there are basically three types: OPC drum (organic photoconductive material), toner drum (Se selenium) and ceramic drum (a-si ceramic). From the point of view of life, the life of OPC drums is relatively short, generally only about 3,000 pages, and of course the price is the cheapest. The life of the Se drum is about 9,000 pages, and the life of the a-si drum can reach 90,000 pages. The price naturally rises by analogy. In terms of composition, the general OPC toner cartridge 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 composed of four to five layers of material. Especially for ceramic drums, its fourth layer is the first protective layer, and the fifth layer is the second protective layer.Key words:copier drum unit,printer toner drum,canon drum unit...
