Problems solved by technology

[0010] It can be seen that because the inkjet printer manufacturer has set up the process of matching the ink cartridges on the inkjet printer, especially the process of matching whether the ink remaining in the ink cartridge is full, in order to use the inkjet printer provided by the inkjet printer manufacturer normally, the inkjet printer must be used. Ink printer manufacturers provide ink cartridges, which brings inconvenience to users and increases costs, and also limits the fair competition opportunities of other ink cartridge manufacturers
[0011] In addition, because the inkjet printer manufacturers set up the inkjet printer of the inkjet printer to check whether the ink remaining in the ink cartridge is full or not, it is necessary to modify the ink cartridge and fix the piezoelectric sensor module. Therefore, the ink cartridge without ink Unable to recycle and reuse, causing environmental pollution

[0099]In the present invention, the circuit for simulating the stimulus response characteristic can also be connected with the storage chip bound on the ink cartridge, specifically, the control unit of the storage chip can be connected with the oscillation circuit. When the memory chip detects that the ink remaining in the ink cartridge is empty in the stored printing information, it sends a control signal to the oscillation circuit of the circuit through the control unit. After the oscillation circuit receives the control signal, it changes the oscillation circuit to receive The characteristics of the excitation response obtained after receiving the excitation signal, that is, the resonance characteristic of the excitation response indicating that the ink in the ink cartridge is empty, makes the inkjet printer know that the ink in the ink cartridge is empty, and informs the user to replace the ink cartridge or / and stop printing.

[0100] In this example, the circuit used is ...
