Several reasons and solutions for uv printer nozzles failing to eject ink

1. The software printhead voltage is missing
If the nozzle is burned out, replace it with a new nozzle; if the nozzle plate is faulty, replace it with a new nozzle voltage board.

2. The nozzle communication is missing and the network cable is loose
Check the position of the interface of the uv printer nozzle, whether the flat wire is loose or broken, and if so, replace it with a new one.

3. Negative pressure is not in the working range
Just adjust the negative pressure value of the uv printer and let it return to the normal working range. (In view of the different fluctuations in the added value range of equipment from different manufacturers, it needs to be recorded in advance for later use), you can choose the software automatic mode manual mode, or you can choose the manual mode.

4. There is a problem with the ink supply
Check whether the uv ink has expired, whether there is condensation, and whether there is a problem with the quality. These will make the uv printer print head out of ink. If any of these problems occur, just replace the ink with a new one.

5. The temperature of the software nozzle is missing
Check whether the heating device of the printhead of the uv printer is operating normally, but some equipment does not have this device, so you can install an external heater, heating fan, etc. to ensure that the temperature of the printhead is within the normal working range.

6. The ink path and nozzle are blocked
It is recommended to replace the ink tube with a new one every 6 months. When the ink path and nozzle are seriously blocked, use a special cleaning solution to clean it. Learning to clean is an important step in maintaining the nozzle. It can be judged that the blockage problem has been solved according to the beaded lines ejected from the nozzle of the uv printer.

7. Nozzle board failure
The failure of the printhead board will cause the uv printhead to fail to discharge ink normally. If these problems occur, you only need to report them to the manufacturer, and the board will be covered by the warranty.
8. The nozzle is damaged
There is no other way to replace a new uv printer nozzle. What needs to be remembered is that the equipment must be grounded, must have an independent power supply, and must be equipped with a voltage stabilizer.
