If the printer reports a high voltage fault.

This may be due to the excessive ink plug factor caused by the poor grinding water quality, which directly leads to the plug factor is a parameter directly related to the particle size of the pigment in the ink. The nozzle is blocked. If the plugging factor is large, the particles are also large. If the ink with larger plugging factor is used, no problem may be found in a short period of time, but with the increase of usage, the filter will be blocked gradually, causing damage to the ink pump, and even some large particles will pass through the filter, causing permanent plugging of the ink head, causing serious damage to the ink head. The troubleshooting method is to use the original ink provided by the manufacturer.

It can check whether the high-voltage deflection plate on the print head is clean. The absolute values of the two plates of the high-voltage deflection plate are different, which will cause the high-voltage fault of the inkjet printer. If the printer reports a high voltage fault. And clean. If your inkjet printer often reports a high-pressure fault, the problem may be more complex, which may be caused by the high-pressure sensor is too sensitive. In addition, the ink points may not split well. It can be checked and adjusted accordingly. If it can't be repaired by itself, the professional inkjet printer company shall be contacted in time, and the professional inkjet printer Engineer shall repair the inkjet printer on site.

It leads to insufficient ink supply, insufficient ink-jet and color fault. Especially in winter, too high viscosity of ink will cause ink to stick in the ink pipe. The temperature is low, this kind of phenomenon is more prominent. The troubleshooting method is to increase the indoor temperature (such as turning on the air conditioner, using the dryer, electric heater, etc.) to reduce the viscosity of the ink or use the ink with lower viscosity.
