Ink cartridge chip applied in ink cartridge, ink cartridge, and ink cartridge adapter
The application provides an ink cartridge chip applied in an ink cartridge which is detachably installed in an imaging device. The ink cartridge chip includes an interface unit and a control unit. The interface unit receives a light control command from the imaging device, which may be a light-lighting-up or a light-extinguishing command. The control unit is connected to a light-emitting unit, and lights up the light-emitting unit on detecting that the ink cartridge chip is in a power-up initialization stage. And the control unit is also connected to the interface unit, and determines, in a case that the light control command is a light-extinguishing command, whether a preset extinguishing condition is satisfied, extinguishes the light-emitting unit if the preset extinguishing condition is satisfied, and maintains a current state of the light-emitting unit if the light control command is a light-lighting-up command.
