(54) Cartridge, cartridge chip, light-emission control method and device for cartridge chip


(57) A light-emission control method for a cartridge chip is provided. The control method includes: determining whether it is currently in a stage that an inkjet imaging apparatus prompts a cartridge state, when the inkjet imaging apparatus begins to supply power to the cartridge chip; determining whether a current cartridge state meets a preset condition, in the case that it is currently in the stage that the inkjet imaging apparatus prompts the cartridge state; emitting light according to a preset light-emission rule to prompt a user with the current cartridge state, in the case that the current cartridge state meets the preset condition. According to the light-emission control method, it is beneficial to reduce process requirement and design difficulty for the cartridge chip. In addition, a light-emission control device for the cartridge chip, a cartridge chip and a cartridge are provided.
