How can we avoid clogging of the printer head?

July 23, 2020

It is very troublesome for the print head to be clogged. In addition to affecting the normal work, it also requires professionals to visit for maintenance and other expenses. Below we will tell you how to minimize the clogging of the printer head.

 

1.Selection of light box cloth: The surface roughness of the light box cloth directly affects the generation of static electricity. Try to choose a light box cloth with a low CaCO3 content and a smooth surface.

 

2.When performing air ventilation in the operating room, pay attention to changes in temperature and humidity.

 

3.Using ink with a higher viscosity will have a better antistatic effect. The principle is that the heavier the ink droplet, the smaller the electrostatic effect, but the higher the viscosity, the greater the effect on the piezoelectric crystal of the print head.

 

4.The grounding problem must be taken seriously. Method: The copper plate should be welded well, and the copper wire should be buried in damp soil 1.5 meters below the ground, and the salt water should be poured. It is best to use the whole wire for the ground wire, without any joint, and make good contact with the machine.

 

5.Some customers use electrostatic brushes to solve static electricity is also recommended.

 

6.The humidity around the machine reaches 40-60% relative humidity, so that static electricity generated from the friction of the PVC light box cloth will also be transmitted out of the air, and will not affect the ink droplets on the print head. The standard for purchasing an industrial humidifier is not to consume less than 4 liters of water per hour. If the ventilation is good, try to choose a humidifier with a water consumption of 6 liters/hour. In addition, some customers use spray guns and compressed air humidifiers with good results.

 

7.Try to keep the indoor temperature constant.
