If it is not repaired in time, it will not only affect the production schedule, but also cause permanent plugging, which will make the printer scrap. If you change the nozzle, then the cost can be higher! Therefore, it is especially important to learn a "true skill". Daily maintenance, reduce the phenomenon of plugging, in the face of unexpected situations, can easily deal with!
The "culprit" of the UV printer plugging phenomenon, because the print head is normally printed, the seal is not tight or placed for a long time, the water is excessively evaporated, causing the ink particles to dry at the tip of the fine print head, so that the ink cannot be ejected normally. Or different inks are mixed with each other to produce a chemical reaction, which usually manifests as a failure such as frequent disconnection, missing color, illegible writing, or even normal printing.
We all know that the price of a UV flatbed printer ranges from tens of thousands to hundreds of thousands. The most need for maintenance of the whole machine is the nozzle. The nozzle plug is one of the common problems. Firstly, the cause of the plug is clearly understood. Better solve the problem fundamentally! Share it for everyone today!
Plug cause
Common reasons for UV plugs for UV flatbed printers:
First, [bubble plug] UV ink defoaming performance is not good, bubbles will be generated in the ink, once the bubble enters the nozzle, it is difficult to come out, resulting in air blockage.
Second, [Miscellaneous Plugging] The tiny particles in the UV ink enter the nozzle and are blocked in the narrow passage of the ink.
Third, [filter net plug] Inferior UV ink in the debris and harmful solvents are blocked in front of the filter, it will block after a long time.
Fourth, [dry knot plug] In a long period of time, no nozzle is used, and the ink is dry to cause plugging.
V. [Chemical plugging] UV inks of different natures are used, and debris is caused by chemical reaction.
Sixth, [corruption plugging] occurs when the temperature is high, the bacteria in the UV ink multiply, the ink is spoiled and denatured, and debris appears inside the nozzle.
VII. [Fouling plugging] UV ink itself is made of water when it is produced. The ink is used for a long time. The dirt is in the nozzle, causing the effective diameter of the nozzle to become smaller.
Eight, [oily plug] UV ink vehicles need lubricating oil, will volatilize and spread to the nozzle, changing the physical properties of the nozzle, causing plugging.
Nine, [Electrical plug] The nozzle is equipped with ink or ink cartridge chip electrical performance detection. When there is non-standard ink or chip, the ink valve is closed to different degrees, the ink can not pass normally, and it is called false plug.
X. [dirty plug] The nozzle is exposed to the outside, and dust particles in the air are adsorbed on the nozzle to cause plugging.
In general, the classification and solution of UV printer plugging phenomenon can be roughly divided into two categories: soft plug and hard plug. Understand the cause of the plug, then look at the solution:
The repair of the soft plug, the soft plug block refers to the disconnection fault caused by the viscosity of the ink on the nozzle due to various reasons. Sometimes it only adheres to the surface of the nozzle of the ink outlet. Generally, the cleaning solution can be recovered after repeated cleaning. The operation is simple and fast, without any physical damage; the disadvantage is that the use cost is high, and the cleaning liquid is wasted. Note that the above method should generally not exceed three times. When the printer "plug" is not serious, it should be opened within three times; if it cannot be opened three times, it means that the plug is more serious, and the number of cleanings is not necessarily useful, and it is unnecessary to waste a lot of expensive cleaning liquid. Further processing according to the specific situation.
