Abstract: The present invention provides a method for controlling an ink cartridge chip, the ink cartridge chip and an ink cartridge. The ink cartridge chip comprises an interface unit and a control unit, wherein the interface unit is connected to an image forming apparatus and used for receiving a light control instruction sent by the image forming apparatus; the light control instruction includes a light-on instruction used for indicating the illumination of a light-emitting unit on the ink cartridge chip; and the control unit is used for controlling whether to execute the light control instruction according to the state of the ink cartridge chip when the interface unit receives the light control instruction, and updating the state of the ink cartridge chip according to the light control instruction. The present invention also provides a corresponding control method and an ink cartridge.

Abstract: A storage device includes an interface unit, a storage unit, a detection unit and a control unit. When the detection unit detects a preset trigger condition and the total surplus of the recording material is greater than the capacity of the recording material, the control unit effects the updating of the total surplus of the recording material stored in the storage unit and the erasing of the surplus of the erasable recording material or the consumption amount of the erasable recording material as a calculation value. When the total surplus of the recording material is less than or equal to the capacity of the recording material, the control unit will not actively update the total surplus of the recording material or the consumption amount of the recording material in the storage unit. Provided is a consumption container, which can better manage the data in the storage device.

Abstract: The present invention provides an information storage device and an image forming cartridge for an image forming apparatus. The information storage device comprises at least two communication interfaces, at least two storage units, a detection unit, a first control unit and a second control unit, wherein the communication interfaces are configured to connect with a controller in the image forming apparatus and establish an information communication path between the first control unit and the controller in the case of being connected with the controller; the storage units and the communication interfaces are arranged corresponding to each other; the detection unit is connected with each foregoing communication interface; the first control unit and the second control unit are respectively connected with each foregoing storage unit and the detection unit. By adoption of the information storage device, the quality of executing the task of the image forming apparatus can be improved.

Abstract: An imaging cartridge chip with self-adaptive contacts includes a set of contacts. Each contact of the set of contacts has the function of a full series of contacts. The specific function of each contact in the set of contacts is determined by identifying a signal received by the contact from an external contact.
