Common faults and solutions of UV printer nozzles

During the daily use of UV printer, some small problems and Glitch will inevitably occur. When this happens, don't worry. I sigh that it is easy to solve your problems and help you to ensure production

Aviation protection.

1. UV printer ink breakage phenomenon:

During the printing process, some nozzles may not produce ink. Reason: nozzle channel blockage, improper setting of nozzle working voltage, ink bag blockage

Ink problems and improper negative pressure adjustment can lead to ink breakage. Solution: Press ink, rinse the nozzle with cleaning solution, adjust the working voltage of the nozzle, soak and ultrasonic clean the nozzle, replace the original ink, and adjust it appropriately

Negative pressure value.

2. UV printer garbled code phenomenon:

The screen shows irregular and irregular spray painting. Reason: inkjet data transmission processing error, nozzle board failure, loose or faulty data cable, fiber optic failure, PCI card failure

Image processing issues. Solution: Arrange the nozzles to test each individual nozzle one by one, troubleshoot the nozzle, replace the data cable (nozzle data cable or nozzle board data cable), and replace the car board/fiber optic/PCI card

Reload the screen for processing

3. Abnormal ink output in the fixed area of the UV printer:

The screen, grating bar, and nozzle board are faulty. Reason: Change the screen, change the spray position, and test the spray painting effect of different screens at different positions, such as

If the other images are normal, it indicates that there is a problem with the processing of that image; If all images have ink problems at this point, check the grating bars; If there is still an abnormal inkjet at a certain position when the screen is changed to the spray position, check

Check the nozzle plate. Solution: Reload the screen for RIP processing, clean or replace the grating bar, and replace the nozzle

4. Uneven left and right operation of UV printer nozzle:

The part of the sprayed image is clear and the part is blurry, and the accuracy of inkjet positioning varies among different segments. Reason: The guide rail beam has not been adjusted horizontally. Solution: Re

Newly adjusted crossbeam.

5. Reasons for UV printer nozzle shaking and painting misalignment:

The grating strip is damaged, the belt is broken, and the drag chain is stuck with debris. Solution: Clean or replace the grating strip, replace the belt, and clean the drag chain slot.

6. UV printer collision phenomenon:

Turn on the nozzle and hit the right end. Reason: Positioning fault, grating head fault, and car board fault. Solution: Check/replace the switch, replace the grating head, and replace the nozzle board.

7. Reasons for loud noise from negative pressure air pump of UV printer:

The air pump is loose, the filter is blocked, and the air pump is faulty. Solution: Tighten the air pump and replace the filter/air pump.

8. UV flatbed printer does not turn on and cannot be reset. Reason:

Loose wiring, nozzle board failure, servo board failure, data cable failure. Solution: Reinsert the data cable and replace the nozzle

Board/servo board/data cable.
