Resetting method for multicolor ink box chip ink balance information

Abstract

The invention provides a resetting method for ink level information of a multi-color ink box chip. By setting a resetting indication location, when any of the ink boxes has low ink volume, the ink excess information in all ink boxes is reset for once, thus avoiding the trouble caused by a plurality of resetting, reducing the times of cleaning printheads, avoiding wasting ink and prolonging the service life of the ink boxes.

Description

technical field [0001] The invention relates to a data processing method of an intelligent chip, in particular to a method for resetting information on remaining ink in a chip of a multi-color ink cartridge in an imaging device. Background technique [0002] Most of the ink cartridges used in inkjet printers are equipped with ink cartridge chips. When the ink cartridges are installed in the printer to work, the ink cartridge chips can exchange information and data with the printer. Ink cartridge chips generally store fixed information such as production date, manufacturer, and device code, and are also used to store variable information such as ink remaining. The remaining ink level information is one of the important information recorded in the ink cartridge chip in real time. The printer can calculate the remaining ink level by accumulating ink ejection times and write the remaining amount information into the ink cartridge chip. During the working process of the ink cartr...

Problems solved by technology

[0004] However, when the above-mentioned method of resetting ink remaining information is applied to a color inkjet printer, there will be the following technical problems: since the multicolor ink cartridges used by the color inkjet printer are generally several independent small ink cartridges, or Several independent small ink chambers are set in a large ink cartridge, and the colors of the ink contained in each small ink cartridge or small ink chamber are different. Correspondingly, the remaining amount of ink in each small ink cartridge or small ink chamber is the same. Recorded in a corresponding metering area in the ink cartridge chip, or separately metered by multiple chips, this is an equivalent way for those skilled in the art to complete the color printing task, when a certain color When the ink is almost used up first, that is, when it is lower than a predetermined value, there are generally some remaining inks of other colors. For example, when the remaining amount of black ink is lower than 10%, there may be 25% remaining of magenta ink. At this time, if the information on the remaining amount of black ink is reset, the printer will perform the operation of cleaning the print head before printing, and the magenta ink will also cause loss during the cleaning process, resulting in the amount of remaining ink falling from 25% to 20%. %, if you print again after cleaning, the remaining amount of magenta ink will soon be lower than 10%, the printer will alarm again, and the user needs to reset the remaining amount information of magenta ink, and then clean the print head again. In the process of frequent cleaning of the print head, a large amount of ink is wasted, and the ink remaining information corresponding to each color ink in the multi-color ink cartridge chip is reset sequentially, resulting in frequent interruption of printing and causing inconvenience to users
