Many users of the laser marking machine will encounter the problem that the laser marking machine can see the light but cannot produce it. Now, Foshan Fulan Laser will briefly explain the reason, hoping to help you quickly find out the reason and solve it.

1. During normal operation, words cannot be printed suddenly: check whether the software gives an alarm. If there is no alarm, it may be that the laser has no laser output.

2. I haven't started the machine for a long time, and found that I can't print words after starting the machine: whether the focal length has changed.

3. There is a red light walking track, but it cannot be hit: it may be a focus problem, or the laser does not output (the ultraviolet laser marking machine will not emit light until it is turned on for a few minutes).

4. There is no red light walking track. It may be a galvanometer fault or a board fault.

5. There is a problem with the file. The software cannot recognize the font, so it cannot type.

6. The marking content exceeds the maximum marking range of the machine.

7. After the computer is replaced, it cannot be typed: check whether the software parameter settings are correct.

8. If all the above are checked, the light can still be seen, but no words can be printed: it may be a machine fault. For example, the laser type of the laser marking software is set incorrectly; Wrong light path; The laser power supply is not energized or damaged; The control signal line is broken or the plug is loose or the control card is damaged; Laser failure, etc.

Note: Machines of different brands may be different.

Warm tip: If you encounter problems that you cannot solve, do not repair them yourself to avoid unnecessary losses. It is recommended that you contact the equipment manufacturer or consult Foshan Fulan Laser.
