Abstract
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.
