What is the impact of uv printer voltage on print head printing

The working voltage problem of UV flatbed printer is a very important problem. Since this device is used on the computer + the main control board mobile phone software to carry out the photo output to the copier, the copier here cooperates with each other, and the UV lamp + nozzle sprays the UV ink on the copied material. It is an operation process with many components cooperating with each other and with high accuracy requirements. Anything wrong is a problem. Therefore, all components must be careless. Today, as far as everyone is concerned, the UV printer is a more critical part of the composition. The operating voltage of the UV printer's nozzle main control board is harmful to the nozzle.

Different well-known brand flatbed printers have different nozzle working voltages. For example, the working voltage of epson nozzles is 30V, the working voltage of cyber nozzles is 33V, and the accurate working voltage of nozzles is 38V. The different working voltages of nozzles are for ink. The viscosity of the specified ink is not the same, the viscosity of the specified ink with a high nozzle working voltage is also high, and the viscosity of the specified ink with a low nozzle working voltage is also low, and the two are directly related.

A. The high working voltage of the print head and the low viscosity of the ink will result in excessive ink jet and too fast speed. Ink dots from the reflective surface of the ink dot to the bottom of the nozzle block the nozzle, and burrs and ink floating will continue to occur.

B. If the working voltage of the print head is low and the ink viscosity is high, there will be situations such as no ink ejection, uneven graphics, and non-roundness.

As mentioned earlier, high voltage will increase the bending of the piezoelectric ceramic sheet. If it is in a high-frequency oscillation situation, the piezoelectric crystals inside the nozzle will fatigue and damage and break, and the operating frequency of the nozzle will be too low. The contrast of the interface is endangered. Therefore, the working frequency of the nozzle in the middle of 28V-32V is more suitable.
