Method for controlling regenerated chip, regenerated chip and regenerated ink cartridge

A method for controlling a regenerated chip, a regenerated chip, and a regenerated ink cartridge are provided. The regenerated chip is electrically connected to a printer by means of a first data signal wire and a logic signal wire, and is electrically connected to an ink cartridge chip by means of a second data signal wire. The method for controlling a regenerated chip includes: detecting an operation command sent by the printer by means of the first data signal wire and the logic signal wire; and when it is detected that the operation command is not a selected operation command, sending a data signal to the ink cartridge chip by means of the second data signal wire, wherein the data signal instructs the ink cartridge chip to communicate with the printer.
