Chip of consumable container, chip data recording method and method for preventing cavity data of chip from being abruptly changed

Abstract

The invention provides a chip of a consumable container. The chip comprises a storage unit, a control unit and an interface unit, wherein the storage unit is used for storing the data of the consumable container; the control unit comprises a control part and a judgement part; the control part is used for controlling access operation of the data of the storage unit; the judgement part is used for judging whether the consumption of representation consumables required to be recorded by a printer is smaller than a protection consumption threshold value; when the consumption is smaller than the protection consumption threshold value, the control part sends out a control instruction to record relevant parameters into the storage unit; and the interface unit is connected with the storage unit and the control unit respectively to realize data exchange between the storage unit and the control unit and data communication among the storage unit, the control unit and the printer. The invention also provides a recording method of the chip and a method for preventing the cavity data of the chip of the consumable container from being abruptly changed. By adoption of the invention, the abrupt change of the cavity data of the chip and the abrupt reduction of the chip capacity of a user interface caused by the data abrupt change are effectively prevented, and the invention is convenient to use.

Description

technical field [0001] The present invention relates to a chip structure, a chip data recording method and a method for preventing sudden changes in its capacity data, in particular to a structure of a consumable container chip used in an imaging device, a method for recording data on the chip, and a method for preventing sudden changes in the capacity data of the chip Methods. Background technique [0002] As an imaging device, printers are widely used in offices and homes. Currently, two types of printers are commonly used: inkjet printers and laser printers. The consumables of inkjet printers are ink. Tiny ink droplets are accurately sprayed on the media to be printed to form images or texts. The consumables of laser printers are toner, which prints toner on the media to realize the printing of images or texts. Most of the ink cartridges and toner cartridges There is a chip, and the ink cartridge or toner information is stored on the chip. By accessing the chip, the data...

AI Technical Summary

Problems solved by technology

At present, the chip used in the consumable container is passive, that is, when receiving the record command or record request information of the printer, the relevant information of the remaining amount is recorded in the memory module of the chip; in many cases, even if the ink cartridge (or carbon The ink (or toner) in the toner cartridge) is relatively sufficient, and it is often detected by the remaining amount detection device of the printer. For example, the performance of the ink cartridge (or toner cartridge) is not good enough or the ink (or toner) detection device of the printer is defective. Faults, etc. At this time, when the parameters related to the detected ink volume (or toner volume) are recorded into the chip, it will cause a sudden change in the chip capacity data, so that the capacity suddenly drops on the user prompt interface, causing inconvenience in use. If the above When the sudden change of capacity data occurs when a new ink cartridge (or new toner cartridge) is installed, an incorrect capacity test result will appear, which will not only cause trouble for users, but also lead to distrust and complaints about product quality. Therefore, It is necessary to provide a method that can prevent sudden changes in chip capacity data
