Storage chip, resetting method thereof, consumable item container and imaging equipment

Abstract

The invention provides a storage chip, which includes a communication part and an integrated circuit part connected with the communication part, wherein the integrated circuit part includes a main control unit, a storage unit connected with the main control unit and a power source control unit; the power source control unit is connected with the main control unit and the storage unit; the storage unit includes a metering area, a non-metering area, a non-metering spare area and a serial number area; and the main control unit includes a read-write control module and a reset detection module that are connected mutually. The invention further provides a resetting method for the storage chip, a consumable item container with the storage chip, and imaging equipment. With adoption of the storage chip, the resetting method for the storage chip, the consumable item container and the imaging equipment, automatic resetting of the storage chip can be realized and use is convenient.

Description

technical field [0001] The present invention relates to a memory chip and its resetting method, in particular to a memory chip used in a consumable container and its resetting method. The present invention also relates to a consumable container and an imaging device with the above memory chip. Background technique [0002] The imaging equipment mentioned in the present invention refers to equipment that converts electrical signals such as characters and patterns into visible images on paper and other media, such as inkjet or laser printers, copiers, fax machines and multifunctional machines. [0003] The two commonly used printers are inkjet printers and laser printers. Inkjet printers use ink cartridges containing ink as consumable containers to provide printing ink to the printer to form text or patterns that need to be printed on paper; The toner cartridge with toner is used as a consumable container to provide the printer with toner for printing to form text or patterns ...

AI Technical Summary

Problems solved by technology

[0006] A method for resetting the existing memory chip is to set a reset circuit in the memory chip 13, and the imaging device maintains power supply to the electrical contacts of the memory chip 13, once the control unit of the memory chip 13 detects that the If the data in the storage unit is in an "exhausted" state, the relevant data in the storage unit will be initialized as new data. Since the above reset method must ensure continuous power supply to the storage chip 13, it is only applicable to the contact type (that is, the use of electrical contacts as Communication part) memory chip 13, since the memory chip 13 of the non-contact type (using an induction coil as the communication part) is intermittently powered, its power supply time cannot meet the time requirement for the memory chip 13 to reset all data, which will inevitably lead to some data being out of order. Reset to the initial state, and then cause the occurrence of work abnormal situation or work to stop; And, above-mentioned reset method must spend very long reset time, is not easy to use
