During the operation of UV printers, everyone may have encountered nozzle blockage, which has a negative impact on normal production printing. How can we effectively remedy this heart wrenching and practical problem without delaying production tasks? Below, the editor of Zhongliqi will discuss with you:

There are two reasons for the clogging phenomenon of UV printers:

1、 Ink deposition blockage

 

Due to poor sealing or prolonged stagnation of the UV printer nozzle after operation, the evaporation of water in the ink causes the ink particles to solidify and block the nozzle holes. In the next use, the ink cannot flow out completely, resulting in broken lines.

 

2、 Mixing different inks

 

The impact of UV ink used in UV printers on the nozzle is crucial. The chemical composition of ink from different brands is different, and mixing them can easily cause chemical reactions, leading to printing failures such as broken lines, color loss, and blurry textures. Therefore, when purchasing UV ink, it is important to choose ink from a UV printer manufacturer to ensure quality and after-sales support.

 

After understanding the causes of UV printer clogging, Zhongliqi editor will teach you how to remedy the clogging phenomenon!

 

1、 The built-in nozzle cleaning function in the UV printer driver is easy and convenient to operate, but the cleaning effect is not ideal.

 

2、 If a minor wire breakage occurs, it may be caused by excessive viscosity of the ink on the nozzle, sometimes only adhering to the surface of the nozzle. Generally, dipping in the original ink and cleaning it multiple times can restore it without any physical damage. The disadvantage is that it wastes ink and has a high cost.

 

3、 For blockages caused by chemical solidification or impurities inside the nozzle, the blockage is relatively mild and can be cleaned by soaking in a 95% alcohol solvent for more than 2 hours. The cleaning effect is good, but it takes a long time.

 

4、 In the case of severe nozzle blockage, it is necessary to slowly inject a syringe containing 95% alcohol into the UV printer nozzle to solve the problem of nozzle ink blockage. The effect is fast and thorough, but there is wear and tear on the nozzle.

 

The above are the methods to remedy the nozzle of UV printers. When the nozzle is blocked or disconnected, it can be considered according to the actual situation.
