How to deal with broken ink during UV printing?

At present, UV flatbed printers have been used in many industries, but UV flatbed printers are prone to cable problems. This article will give you a detailed description of the causes and solutions of cable pulls.
Abnormal pull line:

 Auxiliary equipment abnormal line: refers to the line that lacks ink in the entire nozzle or between multiple consecutive ejection points.

Reasons and solutions: No ink jet on the head or insufficient ink supply of UV flatbed printer, or ink sticking on the head due to the negative pressure of the UV flatbed printer. 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.

Feather pull line:
Feathered pull line: This type of pull line is generally a solid line or white line arranged in an equally spaced direction along the direction of the print head. When printing the print head status chart, it can be observed that the splicing position overlaps, is spaced, or has poor feathering.
Reasons and solutions: You only need to check and adjust the belt to make the UV flatbed printer operate normally, and adjust the nozzle transfer position or feathering of the nozzles.
Plugging cable:
Plugged cable: This type of UV flatbed printer cable is generally a "white line" at a fixed position in a certain color channel. In severe cases, there will be multiple "white lines".
Appearance and solution: There are many reasons for the plugging point. For example, the operation mode and environmental factors will cause the pull-out line of the plugging point, the uv ink will shake the ink unevenly, and the process of adding the uv ink will bring some impurities. The cleaning nozzle is not standardized 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.
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 method, you can quickly solve it by yourself.
