Refers to the printer toner cartridges can use the toner cartridge type, in general, will use the manufacturers recommended and matching printer toner cartridges, unless the two different models are filled with, otherwise can not be used. The basic structure, the basic structure of the magnetic drum, is made up of basic base material made of aluminum, and photosensitive material coated on the base material. According to the different photosensitive materials, there are basically three kinds: OPC drum (organic light guide material), selenium drum (Se selenium) and ceramic drum (a-Si ceramic). From the point of view of life, OPC drum life is relatively short, generally only about 3000 pages, of course, the cheapest price. Se drum life is about 9000 pages, a-Si drum life can reach 90000 pages, the price of nature is also followed by the rise of analogy. In terms of composition, the general OPC 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 selenium drum (Se selenium) and ceramic drum (a-Si ceramic) are synthesized from four to five layers of material. Especially the ceramic drum, the fourth layer is the first protective layer, the fifth layer is a second protective layer, and the fourth and the fifth layers are used for protecting the photosensitive layer, so as to guarantee the long life of the magnetic drum. Edit this paragraph There are two types of cartridge: integral type (or integral type) and separated type. In the design of integrated cartridge is mainly the toner cartridge and the photosensitive drum fitted on the same device, when the toner is exhausted or damaged when the photosensitive drum cartridge will be scrapped
