In the process of using the laser marking machine, sometimes the red light of the marking machine does not appear, or there is a red light, but we only see the red light flashing, but the laser can not print. Now let me explain the reason for this problem and the solution.

If the laser marking machine does not emit red light, there are many reasons. One reason is that the light path is moving, but the laser marking machine equipment is not broken. Just adjust the light path. The other reason is that the power module is broken, or the power supply is broken, or the laser focusing position is wrong. There are many reasons for this problem. I hope you can call the supplier to ask about after-sales service, Of course, you can also call the customer service personnel of Minglei Laser, and we will give you the most detailed answers.

If the red light disappears suddenly, the possible reason is that the red light thread head of the laser marking machine is broken, the red line module is broken, the red light socket is loose and misplaced, or the red light pen is broken, which has many reasons for this problem. If there is a problem that everyone can't solve, it is not recommended to solve it by yourself. The best way is to contact the after-sales service and ask them to solve the problem for you. If you solve it yourself, it may become more and more troublesome.
