How to prevent UV printer nozzle blockage? Look here

The prevention and maintenance of UV universal printer nozzles in advance will greatly reduce the probability of nozzle blockage and also reduce the losses caused by waste during the printing process.

1. The nozzle socket should not be touched by hand to prevent oxidation, and liquid droplets or other liquids should not be on its surface.

2. During installation, align the nozzle interface and connect the flat wires in the correct order. Do not forcefully insert them, otherwise the nozzle will not work properly.

3. Ink, cleaning solution, etc. cannot enter the nozzle socket. It needs to be cleaned with alcohol and then dried with non-woven fabric.

4. When using the nozzle, turn on the cooling device to maintain a good heat dissipation environment and avoid damage to the nozzle circuit.

5. Static electricity can cause significant damage to the circuit of the nozzle. When operating the nozzle or contacting the nozzle plug, install a ground wire to eliminate static electricity.

6. If there is a nozzle breakage during printing, printing must be paused for ink pressing; If the nozzle is severely clogged, you can use cleaning solution to clean the nozzle, and then suck out the ink.

7. After cleaning, set a frequency of 10~15 flash sprays for 5 seconds to ensure smooth nozzle channels and avoid color fading.

8. After printing is completed, reset the nozzle to the moisturizing area of the ink stack and apply cleaning solution.

9. Simple cleaning: Use nonwoven fabric or other materials dipped in nozzle cleaning solution to clean the ink outside the nozzle, and use a straw to suck out the residual ink inside the nozzle to keep it unobstructed.

10. Moderate cleaning: Fill the syringe with cleaning solution before cleaning; When cleaning, first remove the ink tube, then insert the cleaning tube into the ink inlet of the nozzle, allowing the pressurized cleaning solution to enter the nozzle from the ink inlet tube until the ink inside the nozzle is completely washed away.

11. Deep cleaning: For nozzles with severe blockage, they must be removed and thoroughly cleaned. They can be soaked for a long time (to dissolve the condensed ink inside the nozzle) for 24 hours, and should not be too long to avoid corroding the internal spray holes.

12. Different types of cleaning solutions correspond to different nozzles. Ink specific cleaning solutions should be used to avoid different cleaning solutions corroding the nozzle or incomplete cleaning.
