Abstract: A remanufactured ink cartridge and a method thereof are provided in the present disclosure. The remanufactured ink cartridge is suitable for an inkjet printer with an ink-suctioning needle and a limiting protrusion which are configured to be adjacent with each other; an original ink cartridge includes a case and an ink discharge part; a cavity for storing the ink is formed in the case; the cavity is separated by a separation plate into a first cavity and a second cavity which are connected to each other through a channel. The remanufacturing method includes forming a limiting groove facing the cavity on the case and adjacent to the ink discharge part, wherein the limiting groove is connected to the second cavity, configured to allow the limiting protrusion to enter the second cavity; and blocking the channel to cut off a fluid connection between the first cavity and the second cavity.

Abstract: Remanufactured ink cartridge and method of making the same are provided. The method includes providing an ink cartridge, including a polyhedron for containing ink and a first engagement part on the polyhedron; providing an external body including a second engagement part; forming a modified ink cartridge by at least cutting off the first engagement part from the ink cartridge; and forming a remanufactured ink cartridge by combining the external body with the modified ink cartridge. The remanufactured ink cartridge is capable of being interchangeably used with a target ink cartridge.
