The high pressure deflection plate of the inkjet printer is a key part of the inkjet printer nozzle. After the high voltage deflector plate is electrified, there will be a certain high voltage electric field between the two plates. The droplet is charged at the charging pole and enters the high voltage deflector, deflecting under the deflection electric field. Changing the electric charge of the droplet or changing the electric field intensity between the high voltage deflector can change the deflection displacement of charged droplet. The polarity of the voltage between the deflection plates ...
