Storage chip, reset method thereof, consumable container and imaging device

Abstract

The invention provides a storage chip. The storage chip comprises a control unit and a storage unit which is connected with the control unit, wherein the storage unit comprises a metering area, a non-metering area and a spare area, and the control unit comprises a read write unit, a reset detection unit and an authorization judgment unit. The invention also provides a reset method of the storage chip, a consumable container with the storage chip and an imaging device. By adopting the storage chip, the reset method, the consumable container and the imaging device, provided by the invention, the storage chip is suitable for consumable containers with various capacities, and the situation of the occurrence of warning of low or exhausted consumable allowance is avoided.

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. 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 that need...

Problems solved by technology

[0004] When the consumables container is installed on the imaging device, the imaging device reads data from the storage unit in the memory chip 13 to determine whether the consumables container is suitable for the imaging device; when the consumables container is used for a period of time, the imaging device will also read the data The remaining amount of consumables or the percentage of remaining consumables or the number of imaged pages in the storage unit to judge whether it can continue to work. The memory chip 13 writes the information indicating that the consumables are exhausted, indicating that the consumables container can no longer be used. At this time, a method is to produce a consumables container with a higher capacity than the existing consumables container, and install it on the consumables container. In the original storage chip 13, since the total imaging volume stored in the storage chip 13 is still the total imaging volume of the original consumable container, when there are still a large amount of consumables in the consumable container, the storage chip 13 will prompt "the consumables are exhausted". situation, waste

There is an existing consumable container whose capacity is set to be 70% higher than the original capacity. The consumable container still uses the original memory chip 13, and the imaging device still works according to the total imaging volume data stored in the memory chip 13. This will lead to When the remaining amount is still large, the imaging device will prompt the information of "low consumables" (report low) or "consumables exhausted" (report exhausted), which will affect the normal operation of the consumable container. If the user replaces the consumable container at this time, it will Resulting in wasted supplies remaining in the supplies container

In order to avoid the above situation, the total imaging capacity of the existing memory chip 13 is generally set to multiples according to its multiple, so that the memory chip 13 is suitable for consumable containers of different capacities. This type of memory chip 13 is generally called a capacity expansion chip. However, The capacity expansion chip can only be applied to the consumables container whose capacity is an integer multiple, and cannot be applied to the consumables container whose capacity is not an integer multiple; moreover, since the storage unit of the capacity expansion chip stores measurement data of different capacities, when the remaining capacity of the consumable reaches each capacity When the "report low" value or "report exhausted" value, the expansion chip will display the prompt of "low consumables" (report low) or "consumables exhausted" (report exhausted). In this way, the expansion chip will report exhausted many times or reported low, which brings trouble and inconvenience to users, and some users even mistakenly think that the consumable container can no longer be used and discard it, resulting in waste
