How long a toner cartridge can last includes two indicators. One is the number of papers that can be printed. This is related to the weight and quality of the toner and the size of the toner bin. Generally, when purchasing a toner cartridge, the number of printed sheets will be marked (the international standard is A4 paper Calculated at a coverage rate of 5%, it means that each piece of A4 paper prints so much content, how many pages can be printed), the greater the number of printable pages, it is obvious that the toner cartridge can be used longer.

Another indicator is the photosensitive drum, the core component of the toner cartridge, which is related to the life of the toner cartridge. The factors that affect the photosensitive drum are the different photosensitive materials. Toner cartridges can be classified according to different photosensitive drums: OPC toner cartridges (organic photoconductive materials), Se toner cartridges and ceramic toner cartridges. In terms of service life, OPC toner cartridges generally have a lifespan of about 3,000 pages, Se toner cartridges have a lifespan of 10,000 pages, and ceramic toner cartridges have a lifespan of 100,000 pages.
