After the laser marking machine has been used for many years, various problems may occur. Recently, some netizens asked that the laser marking machine has light but cannot print. The description of this kind of problem is not clear enough. We can only check one by one. Only after the problem is determined can we know what the reason is. Let's take a look at it together. 1. The laser is not powered on. In this case, the existing red vibrating lens is also moving, but the laser cannot be emitted, because the laser is generated through the laser. You can check whether the laser is damaged, and then check whether the laser is powered on. The power of the laser is normal. It is 24v, we check whether the input current is 220v and the output is 24v, so we can judge whether the laser is powered off. 2. The control card is not powered on. It is almost the same as the above situation. There will also be a state of red light, but the laser cannot be emitted. The solution is to first check the circuit, check the usb, and then check whether the control card is damaged. The function of the control card of the laser marking machine is to control the input of the laser and the movement of the vibrating lens. 3. The focal length is incorrect. When the laser marking machine is marking, it needs to focus just like the camera. Only when it is in focus can it be correctly lit. Therefore, we must set the focal length of the laser marking machine and the method of focusing. It is to draw a graph randomly first, then turn on continuous marking, then adjust the column of the laser marking machine up and down, and then the strongest light and sound (applicable to fiber laser marking machine) appear, which is the focus. 4. Material issues. Optical fiber marking machines generally have a better effect on metal, and some plastics, so there are some materials that do not respond, such as ceramics, or glass, or transparent materials, which cannot be marked. This Sometimes it is normal that the light cannot be printed out. If we want ceramics, or glass, or transparent materials, we can use a carbon dioxide laser marking machine. If it is a carbon dioxide laser marking machine, it is not allowed to mark on the metal. The principle is the same as the former. 5. The power problem. Sometimes different materials require different power, but we did not adjust the power after adjusting it. That is to say, the power is too low. We can adjust the power to 100% first and then mark it to see if there is any response. If there is a response, we can adjust the parameters to the appropriate value. The above is the problem that the laser marking machine has light but cannot print. The factors of these problems may be more than the above. We will only list some of them here. Hope can help you.
