How to achieve a permanent chip
1. Recycle the original toner cartridge, take out the chip, and remove the encryption control aboveIC
2, the chip is equipped with a communication interface unit, encryption control.ICand control resetICAnd the implementation of communication interface unit, encryption control.ICand control resetICWiring for communication;Will encrypt controlICand control resetICweldedPCBBoard, completed the production of permanent chips;
3. When the permanent chip is installed on the toner cartridge, it can communicate with the printer through the communication unit interface. Each time the power-on and power-off is completed (restarting the printer or switching the front cover of the printer is a power-on and power-off process), the permanent chip will reset the memory in the control.ICThe initialization data in the data backup unit overwrites the data in the data cache unit, that is, after each power-on and power-off, the data recorded in the permanent chip is automatically updated, so when the printer reads the chip, it is displayed as a new drum.
In this way, every time the power is cut off and supplied, the toner cartridge detected by the printer is a new toner cartridge, which makes the printer unable to report the error code of replacing the toner cartridge, thus realizing the permanent use of the toner cartridge. When the clarity of the printed paper becomes worse, the user will add toner by himself.
Therefore, each time the user opens or opens the front cover of the printer, the mainboard powers off the permanent chip; and each time the power is turned off or the front cover of the printer is closed, the mainboard powers the permanent chip. According to the characteristics of the printer motherboard to the chip and power supply, the chip system will be reinitialized to update the data recorded by the chip. That is, the initial data of the backup unit is transferred to overwrite the original chip record data. When the printer motherboard sends a verification command again to verify the data stored in the chip, it is recognized that the chip is updated data, that is, the amount of toner is100 percent of the amount. In this way, the amount of data ink in the chip data storage area can be realized by restarting the printer or switching the printer front cover.100%, the amount of data powder of the chip recognized by the printer is100%State, so that the data recorded by the chip cannot reach the lower limit set by the printer, and the printer cannot report the error code for replacing the toner cartridge, the printer can work normally without restriction and realize the purpose of permanent use.
