During the process of operating UV printers for printing production tasks, everyone may encounter nozzle blockage, which has a negative impact on normal production and printing. It can cause the print job to press the pause button, which has a significant impact. Faced with this worrying reality, how can we effectively remedy it without delaying production tasks? The following will discuss with you two main reasons: the two main causes of UV printer blockage, and finding the problem can efficiently solve it. Firstly, ink deposition blockage, which is a highly probable situation, should be paid more attention to. After the UV printer works, if the nozzle seal is not tight or if it is not used for a long time, the evaporation of water in the ink will cause ink particles to solidify and block in the nozzle holes. Therefore, the next time the UV printer is used, the ink cannot completely flow out, resulting in wire breakage and inability to print normally. 2、 Mixing two different inks together should be avoided, and this issue must be taken seriously. The impact of UV ink used in UV printers on the nozzle is very important. Different brands of ink have different chemical compositions, which can easily lead to chemical reactions and printing failures such as damage, color loss, and texture blurring. Therefore, when purchasing UV ink, it is necessary to carefully weigh and choose the appropriate ink, and select the matching ink from the UV printer manufacturer to ensure quality and effective after-sales service, and to serve customers well. After understanding the two main reasons for UV printer blockage, we will teach you how to quickly remedy the blockage phenomenon from four aspects, restore production printing jobs as soon as possible, and not delay production: First, you can use the nozzle cleaning function in the UV printer driver program, which is crucial and easy to operate, but sometimes the cleaning effect is not ideal, and sometimes other steps need to be coordinated for cleaning to solve the problem. 2、 If a slight fracture fault is found, attention should be paid to it, which is usually caused by the high viscosity of the ink on the nozzle. Sometimes it only adheres to the surface of the nozzle. Generally speaking, it can be restored by dipping in the original ink and cleaning it several times, which will not cause any physical damage. This is an effective method, but the disadvantage is that it wastes ink and has high cost. However, if there is a loss, there is a gain. After repair, it can be immediately put into operation, which can create greater economic value. 3、 Sometimes blockage is caused by chemical curing or impurities in the nozzle. In this case, soaking in 96% alcohol solvent for more than 2 hours can solve the problem, and the cleaning effect is good. 4、 A spare syringe containing 96% alcohol is needed to slowly inject 4 of them into the nozzle of the UV printer to solve the problem of ink blockage. The effect is rapid and thorough, but it wears out the nozzle. 4： If you find that the nozzle is severely blocked, you need to slowly inject a syringe containing 96% alcohol into the UV printer nozzle to quickly dissolve the dry and hard ink, in order to solve the problem of severe ink blockage in the nozzle. The effect is fast and thorough, but the disadvantage is that it may cause some wear and tear on the nozzle. However, special issues should be treated differently. Everything has two sides, and solving the problem is enough.
