Universal chip and data communication method thereof

Abstract

The invention provides a universal chip arranged on a consumable container. The universal chip comprises a substrate, a communication unit arranged on the substrate and an integrated circuit connected with the universal chip, wherein the integrated circuit comprises a control unit, a storage unit, a data acquisition unit, a logic comparison unit and an information conversion unit; the storage unit is used for storing information related to the consumable container and comprises a universal information area and a special information area; the control unit is used for controlling the access of the information in the storage unit; the data acquisition unit is used for acquiring external identification information; the logic comparison unit is used for comparing whether the type of the identification information is consistent with the printer type in the special information area; and the information conversion unit is used for converting the universal information in the universal area into universal information corresponding to the identification information to communicate when a compassion result is inconsistency. The invention also provides a data communication method of the universal chip. By adopting the invention, the chip can still be normally used when the chip is repeatedly arranged on different models of printers and is convenient to operate.

Description

technical field [0001] The invention relates to a general chip and a data communication method thereof, in particular to a general chip used for a consumable material container and a data communication method thereof with a printer. Background technique [0002] The two commonly used printers are inkjet printers and laser printers. Inkjet printers use ink cartridges containing ink as consumable containers to provide printers with printing ink 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 to be printed on the medium. [0003] Chip 10 is generally all installed on the housing of existing ink cartridge, and chip 10 structure is as follows: figure 1 As shown, it includes a substrate 11, on which a communication unit for receiving signals and electric power of the printer and an integrated circuit 12 for realizing communi...

Problems solved by technology

However, due to the use of general information as the general metering area of ​​multiple printers, when the total printing volume of each printer is different, that is, the size of the consumable container of each printer causes a difference in the amount of consumables contained, resulting in a deviation in the total printing volume. At this time, if the general-purpose chip is used on a certain printer for a period of time, and then used on another printer, the data recorded during the printing process will have errors with the actual data, especially when the deviation is large. Large; for example, the toner cartridge of type A printer has a printing capacity of 1500 pages (5% coverage) and the toner cartridge of type B printer has a printing capacity of 3000 pages (5% coverage). After printing 750 pages on the printer of type A, the remaining printing volume is (1500-750) / 1500*100%=50% of the total printing volume, and the 50% is recorded in the general information area. The toner cartridge is installed in the B-type printer, and the B-type printer reads that the remaining amount is 50%, that is, it is considered that 3000*(100-50)%=1500 pages have been printed, and the remaining 3000-1500=1500 pages, but in fact There are 2,250 pages remaining, which will lead to incorrect measurement of consumption and insufficient output of total printed pages; on the contrary, if the toner cartridge prints 750 pages on a printer of type B, the remaining print volume will be (3000-750) / 3000 of the total print volume *100%=75%, and the 75% is recorded in the general information area, when 75% of the used toner cartridge is put into a printer of type A, the printer of type A will read the remaining amount as 75%, which means it is considered complete 1500*(100-75)%=375 pages were printed, and the remaining 1500-375=1125 pages, but in fact there were only 750 pages left to print, which resulted in consumption measurement errors and the printer finally printed pages that turned white. Indicates that the toner is exhausted; the above situation not only seriously affects the printing quality, but also brings great inconvenience to the user; and in the actual operation process, some printers use the number of printed pages to measure the remaining amount. Installed on a printer with a large deviation in total page output, because the data length of the metering area of ​​the chip is different, but the initial data of the general information area is the same, the data overflow of the metering area of ​​the general information area will occur after printing for a period of time, which will cause the printer to report an error , so that the toner cartridge cannot continue to be used, so it is particularly important to propose a general-purpose chip that can be repeatedly installed on different printers and still be used normally
