1. Accept information
This information mainly includes the print volume of the toner cartridge, the amount of toner, and the coverage of toner. However, 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. This is why the chip needs to be replaced. In the chip program, the toner cartridge is a bucket of consumed water, and there is no possibility that it will fill up again, and it is an underwater fish itself. When the water dries, the fish will die.
2. Store information
As mentioned earlier, it will store the information that the printer feeds back to it, which is only part of the information it stores. The toner cartridge chip also stores the toner cartridge model and area information, which means that the toner cartridge chip can only work when it encounters a suitable toner cartridge. This also determines that the toner cartridge chip is incompatible in different toner cartridges and different printers.
Feed back this information when the printer needs it. When people using printers need this information, they can give them feedback.
4. Control printing
The toner cartridge chip controls whether the printer continues to print. When the printer determines that the toner is low, the printer cannot continue to work.
