[0002] A printer is one of the output devices of a computer, used to print the results of computer processing on related media. An inkjet printer turns colored liquid ink into tiny particles through a nozzle and sprays them onto printing paper. Some inkjet printers have three or four print heads to print yellow, magenta, cyan and black. If more colors need to be printed, more heads are needed. Some printers share one head, and the ink is pre-mixed before entering the nozzle for inkjet.

[0003] Among them, for printers that share a common nozzle, when the ink is mixed, although the mixed ink in the previous tube enters the nozzle for inkjet printing, there will still be some residual ink in the tube, and each printing has certain variables. Although the corresponding amount of ink can be pre-mixed according to the computer's printing volume, there will be a situation where the printing volume increases or decreases, which may easily lead to insufficient or residual internal ink. When it is insufficient, you can continue to mix the color, but the residual mixing ink is easy to contaminate the subsequent ink, affecting the accuracy of the subsequent ink mixing.
