Reasons and Solutions for No Ink from Nozzle of UV Flatbed Printer


There are 8 reasons for the failure of the uv flatbed printer, which will inevitably occur during the use of the equipment. According to the differences in the design of uv flatbed printers from different manufacturers, there may be 10 reasons. There may be 6 different reasons. However, mastering the following 8 types can solve 99% of the failures of the nozzles not producing ink.

1. Negative pressure is not within the working range
The negative pressure value of the uv flatbed printer needs to be adjusted to return to the normal range. (In view of the different fluctuations in the added value range of equipment of different manufacturers, it needs to be recorded in advance for later use), you can choose manual mode or software automatic mode.

2. Problem with ink supply
Check whether the uv ink itself is expired, condensed, or has quality problems, which will cause the print head of the uv flatbed printer to not ink. If these phenomena occur, you can replace it with a new one by yourself.

3. The ink path and nozzle are blocked
When the ink path and print head are seriously blocked, it needs to be cleaned with a special cleaning solution. It can be judged that the blockage problem has been solved according to the bead-like lines ejected from the print head of the uv flatbed printer. It is recommended to replace the ink tubes with new ones about 6 months .

4. The software printhead temperature is missing
Check whether the heating device of the printhead of the uv flatbed printer is normal. If the device itself does not have this device, an external heater, heating fan, etc. can be installed to ensure that the printhead of the printhead is within the normal working range.

5. The software printhead voltage is missing
If the printhead is burnt, it needs to be replaced with a new printhead; if the printhead board is faulty, you can contact the original UV flatbed printer manufacturer and ask them to send a new printhead voltage board to replace.

6. The nozzle communication is missing and the network cable is loose
Check whether the flat line of the uv flatbed printer nozzle and the position of the interface are loose, broken, etc., and replace it with a new one.

7. The nozzle is damaged
You can only replace the new uv flatbed printer nozzle. Remember that the equipment must be grounded, must be independent of the power supply, and must be equipped with a voltage stabilizer.

8. Printhead board failure
The failure of the printhead card will cause the UV flat printhead to fail to discharge ink. This situation can be reported to the manufacturer, and the card is within the scope of the warranty.
