Why does the industrial inkjet printer have scattered dots when printing?

Firstly, check it whether the machine is damaged.

Secondly: 1. It may be that the spray hole of the spray gun head is blocked, but it is not completely blocked, so the ink droplets ejected from the spray hole are not straight, so the spraying content becomes scattered. Just remove the nozzle and clean it.

2. In addition, the voltage of the nozzle is too high, the spraying force increases, and the spraying material is just very hard. Just reduce the voltage.

3. If the printing interval is too long, it will also cause scattered spots in the printing. In addition, the aging of the head of the inkjet printer will also produce dispersion points if it does not reach the maximum interval of inkjet printing.

4. Due to the unstable transportation of spray printing products, spray printing scattered points are generated. In addition, when other signals interfere with the signal of the inkjet printer, scattering points will also appear.

5. When using the inkjet printer, pay attention not to mix different inks. Even inks with different production dates are not allowed, otherwise, the nozzle of the inkjet printer will be blocked and cannot be sprayed.
