Consumable chip, consumable container and data writing method for consumable chip

Abstract

The invention provides a consumable chip, a consumable container and a data writing method for the consumable chip. The chip is provided with a substrate, wherein the substrate is provided with a communication unit and an electronic module which is electrically connected with the communication unit; the electronic module is provided with an interface unit, a control unit for receiving a signal transmitted by the interface unit, and a nonvolatile memory connected with the control unit; and the control unit is provided with a data register for temporarily storing data which are not written into the nonvolatile memory in time. The method comprises the following steps that: the control unit receives data needing to be written into the nonvolatile memory, and judges whether the data size of the received data is greater than a preset data size, and if so, stores data exceeding the preset data size in the data register; and the control unit writes data within the preset data size into the nonvolatile memory, and writes the data in the data register into the nonvolatile memory. According to the invention, data transmitted by an imaging device can be completely written into the nonvolatile memory, and the work of the imaging device is not influenced.

Description

technical field [0001] The invention relates to the field of printing, in particular to a consumable chip mounted on a printing consumable, a consumable container equipped with the consumable chip, and a data writing method for the consumable chip. Background technique [0002] As a common office equipment, printers provide great convenience for modern office. Existing printers are divided into inkjet printers and laser printers. Inkjet printers use ink cartridges containing ink as consumable containers to spray ink on paper to form text or patterns that need to be printed on paper; laser printers use ink cartridges containing toner The toner cartridge is used as a consumable container to form text or patterns that need to be printed on the medium. [0003] see figure 1 , an existing color inkjet printer has a casing 11, figure 1 The inkjet printer is shown with the chassis 11 omitted. The machine core 12 of ink-jet printer is provided with in the casing 11, and is provi...
