Five Reasons for Burning Print Head of Digital Printing Machine

The digital printing machine print head can be used to print the best results, and the print head is good, and the ink will be more expressive. The print head is an indispensable carrier for digital printing production, but the operation is not good, the print head is easy to be burned, then everyone knows why the digital print print head is burnt?

There are five reasons why the digital printing machine print head is burnt:

1. The static electricity is too high

Excessive static electricity can affect the printing effect. In severe cases, it can damage the circuit part of the printer. Especially in the autumn and winter seasons, if the human body is too high, if you touch the print head directly, it will easily damage the circuit part of the print head. Therefore, not only the printer has a good and stable grounding, but also the operator is in contact with the machine and the print head. Be sure to do anti-static measures, such as with anti-static meters.

2. The positive and negative poles of the power supply are reversed.

This kind of operation is illegal. During the operation, try to follow the standard operation, especially the print head of the wide-format digital printing machine. If it is not necessary, try not to insert or pull the circuit to avoid the positive and negative connection of the power supply. Reverse operation.

3. Staying in the “dry burning” state for a long time

If the print head of the digital printing machine is in a “dry burning” state for a long time, it is naturally easy to be burned.

4. The working voltage is too high

If the print head is operated under high load for a long time, it is easy to cause aging of the piezoelectric crystal, especially for the piezoelectric print head.

5. Strong corrosive ink or other liquid gets on the printed circuit board

How to get strong corrosive ink or other liquid on the circuit board of the print head can easily cause short circuit, especially solvent ink. Therefore, in the process of processing the print head, we need to pay special attention to not to blot the ink onto the data line interface of the print head, which is likely to cause a short circuit. In severe cases, the print head will be burnt.

The above 5 points are the reason why the digital printing print head is burned, I hope to help you digital printing practitioners.

In the daily production of digital printing, everyone should pay more attention to the maintenance of the print head. If the print head is burned, there is usually no way to recover it. It can only be scrapped and replaced with the print head. This increases the production cost.
