Digital Printing Nozzle

The print head is the most core component of the printer, inkjet printer, and inkjet printer. More than 90% of the effect and quality of the machine's drawing are determined by the quality of the print head. However, the print head is the most expensive among them and the most easily damaged. Because of these particularities, the manufacturer has done various harsh tests before the nozzle leaves the factory, and there will be no quality problems.

Precautions for nozzle replacement:

1. After receiving the nozzle purchased from our company, go back and use a needle to inject water to check the nozzle to see if it is blocked. This is a very redundant and dangerous practice. First of all, once the sprinkler head enters the water, you can turn on the machine before it is dry, which will burn the board at light, and burn the head in severe cases; secondly, the sprinklers sold by our store have been strictly tested and tested It is shipped only after a good time, and it has a protective liquid. If you inject water into the head with a needle, not only will the protective liquid in the head be washed away, but also because the pressure of the hand is too high, it is easy to cause air blockage of the nozzle, resulting in no ink.

2. The head surface of the nozzle is very fragile and must not be bumped, so be sure to protect it. Its surface is a piece of aluminum, and the inner layer is coated with a crystal oscillator and very small ink tubes. When touched, it will be concave, deformed, or even broken, so the nozzle will be scrapped.

3. Be careful when installing the print head, be sure to turn off the power first and install it in place. After installation, push the trolley to move left and right with your hand to check whether it is smooth. Do not turn on the power after installation, because if the head is not in place, the trolley will easily break the head when it moves, and the human hand can feel it, and it can be retracted freely. , strong controllability.

4. When connecting the plug cable, do not bring ink, and make sure that it is in good contact with the socket and does not touch the feet, otherwise the nozzle will be short-circuited and burned.

5. The steel shaft should also be clean and smooth. It can be wiped with a paper towel with some lubricating oil. Do not add oil directly to the shaft. The excess oil will flow to the nozzle and cause damage.

6. After the mechanics and circuits are correct, it is necessary to check the water circuit. First, check that the amount of water in the ink cartridge is insufficient; second, check whether the small cleaning blade and the ink suction pump are dirty.

7. There will be air in the newly installed nozzle, so the printing will not be normal immediately. Only after the air in the head is completely exhausted, can the lines be produced normally; first, intermittent cleaning can be used (clean only 2 times at a time, and then stop for 30 minutes. After cleaning 2 times again) Repeatedly over-cleaning will cause the cleaning pump to accumulate ink, which will not only cause the printing to mix colors, leak ink, but also waste ink; secondly, you can print more pictures to let the nozzles exhaust air during work; Again, if the machine has led out the waste ink tube, you can cut off the power first, and then use a syringe to cover the rubber tube to extract the waste ink tube until 3-5ML of ink is drawn out, then turn it on again, and use the machine to clean it normally once, which is equal to Artificially pulling out the air in the head, the side effect is that it is easy to cause the cleaning pump to accumulate ink.
