After-sales maintenance telephone of inkjet printer, what is the high-voltage fault of inkjet printer?

Charged ink droplets are deflected in the high-voltage electric field (high-voltage deflection plate) to form dot matrix characters together with the movement of the product. High-voltage fault is set to prevent uneven high-voltage electric field or leakage. The root cause of the high-voltage failure of domino inkjet printer is that the absolute values of the two plates of the high-voltage deflection plate are different.

Ink-jet printer is a kind of equipment controlled by software, which marks products in a non-contact way. The theory of inkjet printer was invented in the late 1960s, and it was not until 1970s that the world's first commercial inkjet printer was produced. According to the working principle, it can be divided into continuous inkjet printer (CIJ) and on-demand inkjet printer (DOD). According to different implementation methods, it can be divided into piezoelectric inkjet technology, pressure valve inkjet technology and thermal inkjet technology (TIJ). According to the above principles, inkjet printers can be divided into small-print inkjet printers, large-print inkjet printers and high-definition inkjet printers. Ink-jet printer is a high-tech product, involving many scientific fields, and its working principle is the same, but the technology of each machine is different or slightly different in ink system, ink-jet printing system, software control, electronic system and so on.
