Reasons and solutions for UV printer not inkjet ink

The failure of UV printers to produce ink is one of the common problems during the printing process, this can have a serious impact on print quality and print efficiency.

Now let us understand together what causes the printer not to produce ink. 

Print head clogged 

Clogging of print head is one of the common reasons why UV printers do not produce ink. If the UV ink is not cleaned properly, or poor quality ink is used, Impurities may enter the print head, cause the print head to become clogged. In addition, not using the UV printer for a long time may also cause the print head to become clogged.

Ink is too viscous

If the ink is too viscous, the fluidity will be poor, the ink cannot be ejected normally. At this time, we need to dilute the ink to improve its fluidity.

Dry ink

If the ink is not used for a long time, it may dry out. At this time, we need to solve the problem by cleaning the print head.

Ink tube failure

Ink tube failure is also one of the reasons why the UV printer does not produce ink. For example, the ink tube connection is abnormal or the tube is damaged, etc.

Ink supply issues

Ink supply problems may also cause the UV printer to not produce ink. For example, insufficient ink supply, ink quality problems, etc.

Print head damaged

Improper use may cause the print head to burn out, as a result, the UV printer does not produce ink. At this time, we need to replace the print head with a new one.

Solution to UV printer not producing ink

There are many reasons why UV printers cannot produce ink, and the solutions are also different. When encountering the problem of ink not coming out, we need to analyze and judge based on the actual situation, choose an appropriate solution.

At the same time, regular maintenance and upkeep of the UV printer can also effectively avoid problems such as ink failure.
