How does the voltage of the print head affect the print head?

Let’s talk about the nozzle voltage of the universal printer because the voltage of the nozzle can determine the curvature of the piezoelectric ceramic inside the head, and it should be noted that high voltage can also increase the inkjet volume.

Shenzhen Micolorprint universal printer experts especially reminded: The manufacturer recommends that the rated voltage of the head of the machine should not exceed 35V, and it should be noted that the lower the better without affecting the picture quality. It has been proved by practice that it is necessary to pay attention to the fact that the voltage exceeding 32V may encounter frequent ink breakage of the head, and the current service life is reduced. Moreover, as mentioned earlier, the high voltage will increase the bending of the piezoelectric ceramics, but if it is in a high-frequency oscillation state, the piezoelectric crystals inside the head will be easily fatigued and damaged. However, it should be noted that the working voltage will cause The saturation of the picture to be affected. And paying special attention to the working voltage of the head between 24V-32V is more appropriate. And different brands of universal printers have different head voltages. For example, the nozzle voltage of the Gongzheng Machine is 37V. Different voltages require different ink viscosity, and high head voltage requires high ink viscosity. Moreover, the low voltage of the head requires the viscosity of the ink to be below, and the two are in a proportional relationship.

Additionally, it’s worth noting that the voltage of the print head can also affect the ink droplet size. A higher voltage can create larger droplets, while a lower voltage can result in smaller droplets. This can impact the overall clarity and sharpness of the printed image.

It’s important to consider all of these factors when selecting a voltage for the print head, taking into account the desired print quality, ink viscosity, and lifespan of the print head. In general, it’s best to stick within the recommended voltage range provided by the manufacturer to ensure optimal performance and longevity of the printer.
