The toner cartridge of the laser printer is divided into two types, one is the drum powder integration, that is, the toner cartridge integrated with the photosensitive drum developer roller toner cartridge; There is also a separation of drum powder, and the photosensitive drum is not integrated with the developer roller and powder box. The integrated drum is generally to meet the disposable use, and various manufacturers do not approve of powdering, and the life of the photosensitive drum is not long. Drum powder separation toner cartridge generally a photosensitive drum can meet the needs of replacing several toner cartridges, most drum powder separation toner cartridges on the market have a longer life than the drum powder integration, but the price is relatively high.

Generally, the printing volume of a toner cartridge is between 2000 pages and 6000 pages, and the toner cartridges of most A4 format laser printers are generally about 3000 pages, while the toner cartridges of A3 format printers, network printers, and color printers have a larger toner capacity and a larger number of prints. The amount of printing is relative to the coverage of the font on the output paper, so there is no accurate number of sheets, the higher the printing resolution, the greater the print density, the greater the consumption of toner, and the number of prints that consume large toner cartridges is relatively less. The life of the drum is generally more than a toner cartridge toner used a lot, most of the toner drum life is more than 10,000 pieces, if you pay attention to the use can be replaced several times to save costs.
