The toner cartridge chip is a control component on the toner cartridge. Its function is very simple, receive information, store information, feedback information, and control the printer based on this information.

1. Receive information, mainly including the print volume of the toner cartridge, the amount of toner and the coverage of toner. This information is collected by the printer, and then fed back to the toner cartridge chip for storage. To ensure the normal operation of the printer, the collected information is irrecoverable.

2. Store the information, it will store the toner cartridge model and area information, which means that the toner cartridge chip can only work when a suitable toner cartridge is encountered. This also determines that the toner cartridge chip is incompatible in different toner cartridges and different printers. So there are almost as many models of toner cartridge chips as there are printer toner cartridges.

3. Feedback information. When people using printers need this information, they can give them feedback.

4. Control information. The toner cartridge chip will control whether the printer continues to print. When the printer determines that the toner is low, the printer will not continue to work.
