We usually hear most that the print head is the core part of the UV flatbed printer, but ignores that the UV lamp is also one of the core components of the device. Its main function is to ensure that the UV ink adheres to the pattern surface and can dry quickly. , Dry thoroughly to avoid the phenomenon of fading and falling off the pattern. In the process of long-term use, whether it is the natural aging of parts or improper operation, etc., it will cause failure. There are four common faults: UV lamp dimming, UV lamp does not turn off, UV lamp does not turn on, and UV lamp illumination distance is wrong.
First, the UV lamp is dimmed
1. Whether the knob on the water tank is changed, the solution: twist the knob on the water tank;
2. The internal power supply of the water tank is damaged, the solution: open the water tank, which power line is short-circuited and burned, reconnect and repair it;
3. The UV power cord is damaged, and the solution: replace it with a new UV power cord;
4. The UV lamp belt is damaged, the solution: replace it with a new UV lamp belt;
5. Poor contact, solution: if the interface is loose, re-tighten it;
6. The temperature is too high. Solution: Check the refrigerant in the lower water tank and add new ones.
Second, the UV lamp does not go out
1. The Y-board relay is aging, and the solution: replace it with a new Y-board relay;
2. The software is not turned off to test the UV lamp, the solution: the software is turned off to test
3. The UV control line is short-circuited, and the solution: replace the control line and reconnect it
4. The board card is faulty, and the solution: replace it with a new board card
Three, the UV light does not light up
1. The UV power cord is damaged, and the solution: replace it with a new power cord;
2. The UV lamp belt is damaged, and the solution: replace it with a new UV lamp belt;
3. The internal power supply of the water tank is damaged. Solution: Check and repair the damaged part of the internal power supply. If it cannot be repaired, contact the manufacturer to replace it with a new one;
4. The upper knob of the water tank has 0 power output. Solution: adjust the output power of the lower knob;
5. The control software does not turn on the light, the solution: turn on the control software light;
6. The lamp is damaged, and the solution: contact the manufacturer and replace it with a new UV lamp;
7. The board card is faulty, and the solution: contact the manufacturer and replace the boarding card with a new one.
Fourth, the UV light illumination distance is wrong
1. The power cord of the UV lamp is connected reversely, and the solution: the power cord of the UV lamp is connected positively;
2. There is a problem with the light distance, and the solution: adjust the light on the software.
