The laser marking machine is equipped with a red light indicator system, but does not emit red light. There are mainly the following 5 reasons:

1. The red light is blocked, just adjust it to coincide with the red light and laser;

2. In the marking software, you have turned off the "Red Light Preview" option, you can check this option;

3. The red light indicator is broken, just replace it with a red light pen;

4. The light path is moved, just adjust the light path;

5. Whether the red light is on. One type of red light adjustment is set on the marking software and can be turned on by pressing F1, and the other is a mechanical switch, which can be turned on by turning on the red light power switch;

6. The life of the red light indicator has expired. Use a multimeter to measure whether there is a 5V voltage between the two red and black bars of the red light indicator. If it is 5V and there is no laser output, then the red light indicator needs to be replaced.
