The multi-jet docking code printing device passes through a plurality of ink tubes to the nozzles, shares one ink cartridge, and the centralized ink supply shares a set of ink supply systems, usually called a central ink supply system or a centralized ink supply system. The central ink supply system monitors the amount of ink in the inkjet device ink cartridge. When the ink in the ink cartridge reaches the minimum control line, the system sits an alarm sound to add ink to realize automatic control of the ink supply device. In the process of coding, the control of the ink is an indispensable part of obtaining high quality coding. If the ink in the ink cartridge is too small during the coding process, the ink may be broken, the content of the inkjet code may be incomplete or blurred, so when the ink volume reaches the minimum control line, ink should be added to ensure the quality of the inkjet. This technique is applied to the blood collection label QR code printer. (Automatically supply ink, an alarm is issued when it is detected that the ink in the ink cartridge reaches the minimum control line, and the pump starts to extract ink from another large ink cartridge to supply the inkjet cartridge.) The central ink supply system guarantees the ink output, which effectively ensures the best results when the coding time is maintained, achieves high quality coding and saves ink; automatic control reduces manual labor intensity and avoids manual operation. Possible misuse. In addition, there is no need to replace the ink cartridges, and the startup after reloading the ink cartridges is avoided, and the time, paper, ink, and the like caused by the debugging are wasted.
