Therefore, considering from the aspect of environmental protection, after users add ink to the ink cartridge on the market after using up the ink, the ink cartridge can be recycled only by installing the reset chip unit provided by the invention, which not only can simplify the process steps and increase the convenience of remanufacturing the ink cartridge, but also can reduce the manufacturing cost and greatly reduce the influence of the waste ink cartridge on the environment.
In summary, the present invention provides a reset chip unit, which is installed on an ink cartridge without destroying a flexible printed circuit of the ink cartridge, so that the ink cartridge can be directly applied to the reset chip unit, and the used ink cartridge can be reused by refilling ink. The cost of the additionally arranged reset chip unit is low and is far lower than that of a new ink box, so that the overall production cost can be reduced, and in consideration of environmental protection, after a user uses ink and adds the ink to the ink box on the market, the ink box can be recycled only by installing the reset chip unit provided by the invention, and the influence of the waste ink box on the environment is greatly reduced.
