 How to Solve the UV Flatbed Printer No Ink

uv printer

UV printing is a unique method of digital printing utilising ultraviolet (UV) light to dry or cure ink, adhesives or coatings almost as soon as it's hit the paper, or aluminium, foam board or acrylic 

It is a common problem that UV flatbed digital printers cannot print ink. Some users think that the nozzles are clogged when they encounter the nozzles. Indeed, the biggest possibility that the nozzles of UV flatbed printing machines cannot print ink is that the nozzles are clogged. But like the UV flatbed printer, there is a situation that ink is not output all the way, in addition to the clogging of the nozzle, there may be other reasons, so how to solve the problem that the UV flatbed printing machine does not output ink all the way?

The reasons why UV flatbed printers can't produce ink are as follows:

1. The negative pressure is not in the working range

If the negative pressure is not in the normal working range, you need to adjust the negative pressure value of the UV flatbed printer to restore it to the normal range. You can consult the manufacturer for this negative pressure value and let the manufacturer teach you how to adjust it.

2. Ink problems

We can check whether there is a problem with the UV ink. If the ink expires, condensation and other problems will cause the UV flatbed printing machine nozzle to not produce ink.

3. The ink path and nozzle are blocked

When the ink path and nozzle are seriously blocked, you need to clean it with a special cleaning fluid. You can judge that the clogging problem has been solved according to the beaded lines ejected from the nozzle of the UV flatbed printer. UV flatbed printer manufacturers recommend replacing them at regular intervals.

4. Software nozzle temperature is missing

Check whether the heating device of the nozzle of the UV flatbed printing machine is normal. If the device itself does not have this device, an external heater, heating fan, etc. can be installed to ensure that the nozzle of the nozzle is within the normal working range.

5. Software nozzle voltage is missing

If the nozzle is burned out, it needs to be replaced with a new nozzle. If the print headboard is faulty, you can contact the original UV flatbed printer manufacturer and have it send a new print head voltage board to replace it.

6. Whether the data cable of UV flatbed printer nozzle is loose

Check whether the flat wire and interface of the UV flatbed printing machine nozzle are loose or broken, and replace it with a new one.

7. The nozzle is damaged

Only replace the new UV flatbed printer nozzle, remember that the equipment must be grounded, must be an independent power supply, and must be equipped with a voltage stabilizer.

8. Nozzle board card failure

The failure of the print headboard will cause the print head of the large format UV flatbed printer to fail to deliver ink. This situation can be reported to the manufacturer and the board is stuck within the scope of the warranty.
