We all know that the price of a UV printer ranges from tens of thousands to hundreds of thousands, and the core component of a UV printer is the UV print head, which is what we often call the print head. For printing enterprises, the phenomenon of "plugging" of UV DTF printeroccurs from time to time, which is miserable for users. Leaving the printer for a long time can cause plugs, the improper operation can cause plugs, and poor ink quality can cause plugs. It seems that plugging is indeed a headache.

What is the "culprit" that causes UV printer plugging?
If it is not repaired in time, it will not only affect the production progress but also may cause permanent plugging, making the printer scrapped. If you change the sprinkler head, it will increase the cost. Therefore, it is particularly important to learn the "real thing". Daily maintenance can reduce the plugging phenomenon, and can easily deal with emergencies. The "culprit" of UV printer clogging is that the print head is not tightly sealed or placed for a long time after normal printing, and the moisture is excessively evaporated, causing the ink particles to dry and stick to the fine print head tip so that the ink cannot be sprayed normally. Or different inks are mixed, resulting in a chemical reaction, which usually manifests as broken lines, missing colors, blurred handwriting, and even failure to print normally. Therefore, the right medicine can better solve the problem fundamentally.
There are ten reasons for UV printer plugging.
First, is the bubble plug. The defoaming performance of UV ink is not good, and bubbles will be generated in the ink. Once the bubbles enter the print head, it is difficult to come out, causing air blockage. Second, the debris plug. The tiny particles in the UV ink enter the nozzle and block the narrow channel of the ink. Third, the filter plug. The sundries and harmful solvents in the inferior UV ink are blocked in front of the filter screen, and they will be blocked for a long time. Fourth, dry plugs. If the print head is not used for a long time, the ink dries up and causes the plug. Fifth, chemical plugs. Using UV inks of different properties, after the chemical reaction, debris may cause plugging. Sixth, corrupt plugs. When the temperature is high, bacteria multiply in the UV ink, the ink is corrupted and degenerated, and debris appears inside the print head. Seventh, fouling plugs. The UV ink itself is very hard in water during production. If this type of ink is used for a long time, the dirt will remain in the nozzle, which will cause the effective diameter of the nozzle to become smaller, which often starts with the appearance of horizontal streaks on the nozzle. Eighth, oily plugs. The digital printing machine ink car needs lubricating oil, which will volatilize and spread to the nozzle, changing the physical properties of the nozzle, and causing plugging. Ninth, electrical plugs. The print head is set to check the electrical performance of the ink or the ink cartridge chip. When there is non-standard ink or chip, the ink valve is closed to different degrees, and the ink cannot pass normally, which is called a false plug. Tenth, dirty plugs. The UV printer print head is exposed outside, and dust particles in the air are adsorbed on the print head and cause plugging.
