Abstract

The present invention provides a liquid ejection device capable of solving the problem that ink cartridges with different liquid volume measurement methods cannot be mounted in the same holding part of the conventional inkjet printer. The printer (1) recognizes the ink cartridge via the third interface by installing the ink cartridge (14) on the mounting unit (9), and transmits it as information C to the management unit (19). Based on the information C, the management unit (19) causes the detection unit (16) or the calculation unit (17) to perform liquid volume measurement via the first or second interface. The installation part (9) can be installed with: a first liquid storage body (26), which can detect information A; a second liquid storage body (27), which has a circuit board (18) for storing information B; A storage body (28) is capable of detecting information A and has a circuit board (18). The management unit (19) can determine, based on the information C, whether to use either the information A or the information B, or to use both the information A and the information B.

Description

technical field [0001] The present invention relates to a liquid ejection device. Background technique [0002] Among the inkjet printers that are liquid ejection devices that eject liquid onto a recording medium, there are inkjet printers that use detachable ink cartridges. As a method for detecting the remaining amount of ink in the ink cartridge, there is known a method in which, as in Patent Document 1 and Patent Document 2, an optical sensor or an electrical sensor is used to directly measure the amount of liquid in the ink cartridge below the The method of detecting when the ink is used up at a predetermined threshold, or as in Patent Document 3, calculates the difference between the information on the amount of liquid in the ink cartridge and the information on the amount of liquid consumed from the ink cartridge, and obtains the amount of ink in the ink cartridge method of margin. [0003] The inkjet printers of Patent Document 1 and Patent Document 2 are equipped ...
