When you use the laser marking machine, do you also encounter the situation that the laser marking machine does not emit light? Afraid of affecting the output, but anxious to solve this problem as soon as possible? Now, Foshan Fulan Laser Technology would like to talk to you about the causes and solutions of the failure to emit light.

1. Whether the software reports an error. If there is "unable to find the dongle", let the software find the marking card first. If it is an external dongle, it needs to be plugged in; The device manager checks whether the marking card device is normally installed with the driver; Check whether USB is unblocked; Check the cause of electromagnetic interference on site.

2. Observe whether the marking indicator of the marking card flashes when the software displays marking. If the marking indicator (red light) of the marking card does not flash. Check whether the flight marking is enabled in the parameters. If the flight marking is enabled, cancel the flight marking.

3. Check the laser type setting, set the power to the appropriate size, constantly change the focal length, and observe whether there is light.

4. If water cooling is used, check whether the water circulation is abnormal, whether the water flow is sometimes or not, and whether the water protector has problems.

5. In the parameter setting of the laser marking machine, check whether the laser type is correct. This is the main reason for the failure of continuous light emission.

6. Pull the nine core control line of the laser marking machine, test and observe whether the control line is loose and whether the connection is unreliable.

7. Check whether the lens cover of the laser head is removed.

There are many reasons why the laser marking machine cannot emit light. It may be caused by incorrect selection of laser type, failure of mainboard and wiring board, power supply or control line connection, and cooling water circulating system.

Note: After the UV laser marking machine is turned on, it needs to wait for a few minutes before it emits light.

If the laser marking machine does not work, you can refer to the above contents for operation inspection. 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.
