During the use of UV flat-panel printer, the problem that the nozzle does not produce ink is inevitable. Next, let's talk about the cause of this fault.

1. Ink supply problem

Check whether the UV ink itself is expired, coagulated and has quality problems. If so, please replace it with a new one.

2. Ink path and nozzle are blocked

When the nozzle is blocked seriously, it needs special cleaning fluid to clean. In addition, it is recommended to update the ink pipe once a year.

3. The software nozzle temperature is missing

Check whether the nozzle heating device of UV flat-panel printer is normal. If the equipment itself does not have this device, external heating sheets, heating fans, etc. can be installed to ensure that the nozzle of the nozzle is within the normal working range.

4. Negative pressure is not in the working range

To adjust the negative pressure value of UV flat-panel printer to return to the normal range, you can choose manual or software automatic mode.

5. Software nozzle voltage is missing

If the nozzle is burnt out, it needs to be replaced with a new nozzle; However, if the nozzle board fails, you can contact the manufacturer to replace it.

6. Nozzle board failure

The failure of nozzle board will lead to the failure of UV flat nozzle to produce ink. This situation can be fed back to the manufacturer.

7. Nozzle communication is missing

Check whether the cable arrangement and interface position of the UV flat printer nozzle are loose or broken, and replace it with a new one.

8. Nozzle damage

Only new UV flat-panel printer nozzles can be replaced. Note that the equipment must be grounded, independent power supply and voltage regulator.
