Abstract: The present disclosure relates to the technical field of printer consumables, in particular to threshold variable feedback circuit, consumable chip and consumables. The feedback circuit comprises a control unit; a feedback module including four different feedback units connected in parallel between the output terminal and the ground; each one of the feedback units comprises a gating component and feedback component that are connected in series between the output terminal and the ground; the control unit is electrically connected with the gating component of each one of the feedback units such that the feedback module selects and outputs an electrical signal of one of the feedback units to the output terminal. Selecting different feedback units can generate different feedback voltages to respond to the verification requirements of the imaging device, so that the consumable can pass the verification of the imaging device.

Abstract: The present disclosure discloses a method for reusing an ink cartridge, a system thereof, a readable storage medium and a reused ink cartridge, which belong to ink cartridge in printing field. The method includes detecting each of a plurality of heating elements in the ink cartridge, wherein the plurality of heating elements are located on both sides of nozzles of the ink cartridge; determining one of the plurality of heating elements which is not matched with a printer as a target heating element according to detecting result; and burning out the target heating element. Therefore, the target heating element will not be detected, the ink cartridge will match with the printer in new version, resulting in the ink cartridge can be reused and applied in the printer in new version.
