The causes and solutions of UV flatbed printer cable

        I. Ancillary equipment pull line with abnormal properties: Refers to the pull line lacking ink in the whole nozzle or between multiple consecutive ejection points. The cause of this pull line is that the nozzle does not spray water or the UV flatbed printer does not supply enough ink, or because the negative pressure of the UV flatbed printer is unstable, ink is stuck on the nozzle, etc. But for this kind of cable, it is usually caused by the failure of the nozzle circuit board or the negative pressure pump and ink supply pump. Under normal circumstances, replace the corresponding circuit board and negative pressure pump. Of course, there is another way to increase the frequency of the ink supply pump and periodically change the filter to eliminate the abnormal properties of the auxiliary equipment.

        2. Feather pull line: This kind of pull line is generally realized by the nozzles arranged in a direction that is obviously equidistant from each other or white lines. When printing the state diagram of the print head, it can be observed that the splicing positions overlap, space or have poor feathering. The pull line like this only needs to check and adjust the belt to make the UV flatbed printer operate normally, and adjust the nozzle transfer position or feathering of the nozzle. However, it should be noted that in the case of different grayscale graphics to be printed, the degree of feathering required at the same transfer position may be different.

        3. the cable of the nature of the plugging point: This type of UV printer cable is generally a "white line" in a fixed position of a certain color channel, in severe cases there will be multiple "white lines". There are many reasons for blocking points. For example, the operation mode and environmental factors will cause the pull line of the plugging nature, the uv ink will shake the ink unevenly, some impurities will be brought in during the process of adding the uv ink, and the nozzle will not be cleaned properly when wiping, so that the environmental dust adheres to the nozzle . When cleaning and maintaining the print head, use a sponge to remove other impurities such as dry ink or glaze powder.

        4.When using a UV flatbed printer, users should pay more attention to observation and pay attention to daily cleaning to reduce the occurrence of cable problems. Even if it occurs, there is no need to worry. According to the above methods, you can quickly solve it by yourself.
