Common Fault Phenomena And Handling Methods Of Laser Marking Machine

The laser marking printer does not have ink system faults, so the failure rate of the laser marking printer is relatively low. It shows stability and reliability in the inkjet process of the production line, and the printing effect is clear, which has been unanimously recognized by customers. But this does not mean that lase marking printers do not malfunction or have technical problems, especially since laser marking printers do not have consumables, which makes the service provided by laser marking printer manufacturers higher in door-to-door service costs compared to ink inkjet printers. Therefore, it is particularly important for laser marking printer users to understand the common causes and solutions of laser marking printer faults. Today, the editor of Chengdu Linservice Industrial Printing Technology Co., Ltd. will introduce the common faults and solutions of laser marking printers during use.

After nearly 10 years of rapid growth, a large number of factories have started using laser marking printers for product identification. By using laser marking printers to achieve higher clarity, better anti-counterfeiting effect, and can improve the level of product identification, the identification effect can be achieved. With the increase of ownership, laser marking printers, as a type of inkjet equipment, inevitably encounter various problems and malfunctions. How to quickly handle and reduce the production impact caused by equipment shutdown has become the most concerned issue for operators and users. The common faults of laser marking printers are as follows:

1. The deformation of the laser marking printer's font or the difference in the depth of the printed font result in unclear printing effect. This situation is mostly caused by the energy attenuation of the laser generator or the fast online speed; ​with the increase of usage time, the laser tube of the laser marking printer will decay with the increase of light emission, which will also encounter the problem we mentioned above. The printing effect is not clear, and the feeling is very faint. How to handle it? If it is a CO2 laser machine, based on the usage time, the manufacturer generally recommends a laser tube inflation plan of 2 or 3 years. If the usage time is short and the marking is unclear within 1 year, the power can be increased or the marking speed can be reduced. Increasing the power of the laser tube is a common treatment method. As for the difference in font printing depth, it is also a common malfunction of laser marking printers, and it may also be caused by poor laser focusing. As we mentioned above, the working principle of a laser machine is to emit laser light through a laser tube, deflect it through a polarizing mirror system, burn it on the surface of the product, undergo physical and chemical reactions, and form characters, which can be deep or shallow. One thing we need to pay attention to here is the focus point, which is the adjustment of the focal length. Some laser machines on the market have the function of red light positioning and focusing, which can be clicked and two red lights appear. When the red light gathers together, the focal length is the best time, at which point a clearer spray printing effect can be achieved on the surface of the product.

2. After the laser marking printer is turned on, there is no response. Firstly, check the power system to see if there is a power input at the flat panel display port. If the power supply to the power system is abnormal, there will be no response when the machine is turned on; ​if there is a power input, consider whether the operating system is caused by computer lag. Laser marking printers generally use customized operating systems, standard boards, and computer systems. Common software systems on the market are generally developed based on the WINDOWS platform, and have high performance requirements for computers. If the computer configuration is low, it is easy to get stuck. If you encounter the inability to access the operation interface after turning on the computer, it is recommended to first perform antivirus upgrade processing on the computer. If it still does not work, you can contact the laser machine supplier for remote software reset or upgrade processing.

3. The other common faults and problems of laser marking printers mentioned here cover a wider range, including some relatively rare fault problems, such as laser machine not emitting light, garbled code, system failure, low memory, no response when starting up, power box failure, static code cannot be set, variable QR code cannot be printed, communication cannot be connected, and so on. Classifying other faults and problems mainly takes into account these issues. Without systematic training, it is difficult for general operators to determine the cause of faults and handle them, and they must seek technical support from manufacturers.
