Troubleshooting and working principle of common faults of laser printers

Laser marking machine is a kind of machine that uses a laser beam to evaporate the surface of the material, thereby printing permanent marks, such as exquisite patterns, trademarks, characters, etc., which are widely used in electronic components, tool accessories, exquisite machinery, building materials, etc. In other industrial fields, the laser marking machine reminds you that there will be some faults when using the laser marking machine for a long time. The following is a summary of the troubleshooting methods for some common faults of the marking machine:

Exclusion method: .

The main reason is that the control panel, the network cable connection line is loose, the motherboard, the grounding line is unreliable and a slight high-voltage ignition fault is caused.

Cause of failure: .

During the processing, the machine will reset automatically, and the machine will return to the mechanical origin.

1. Check whether the laser tube or laser power supply is sparking.

2. If there is no problem in the output of the graphics in other formats, it means that the graphics are wrong, and the graphics need to be re-exported or re-created.

3. If you use Wentai output, check whether the path calculation is normal, re-register the laser marking machine or install Wentai, sometimes you need to reinstall the system.

4. Check whether the original graphic has errors, such as the graphic has intersection, unclosed, missing strokes, etc., correct the errors in the graphic, and test at the output.

5. Whether the new software has set 'prohibit output' or not set parameters such as engraving method.

6. Check whether the computer has set a screen saver or power saving mode (such as system hibernation or closed hard disk, etc.), cancel the above settings, and change to 'Never'.

7. Is there a place where the machine is located, strong electricity and strong magnetism.

8. Check whether the connection cable is loose or the buttons on the control panel are in poor contact.

9. Check the grounding condition of the machine, and measure whether the ground wire meets the standard (the resistance to ground should not be greater than 5 ohms). It is necessary to transform the ground wire to meet the relevant standards.

Laser marking machines are widely used in the industrial field. The laser beam prints patterns, patterns, specifications and other requirements on the material. The marking machine summarizes some laser markings. The working principle of the machine is only for reference to the UV laser marking machine:.

Under the control of the computer, the laser is discharged through pulses, thereby outputting a controlled repetitive high-frequency pulsed laser to form a beam with a certain frequency and a certain pulse width. The beam is transmitted and reflected through the optical path and focused on the surface of the processing object through the focusing lens group, forming a small, high-energy density light spot.

The high-energy laser pulse instantly sputters a small hole on the surface of the object. Under the control of the computer, the cutting head of the tube laser cutting machine and the material to be processed are drawn in advance The graphics of the tube are continuously moved relative to each other, so that the object will be processed into the desired shape. The tube laser cutting machine is realized by applying the high power density energy generated by the laser focusing.

For the cutting of carbon steel below 8mm and stainless steel below 4mm, I recommend Wuhan high-energy metal laser cutting machine, which has high cutting precision, high speed and fully automatic IC. The laser marking machine is about 100 times more than wire cutting, and the thermal impact is small. Since this laser cutting equipment is not easily deformed, and the cutting seam is very flat and beautiful, there is no need for post-processing at all.

The laser marking machine is a technical product, and the technical level is very important in the production of life. It also has a great contribution in terms of the overall level of the manufacturers in the middle and lower reaches. The reasons for this are the lack of attention to the industry and the limitations of the enterprises themselves.

The general industrialization relies on the development of the collective group model, gathering a lot of enterprises in one place, which is not only conducive to the transportation of products, but also the competition between enterprises will also promote the products. The current development situation cannot meet the requirements. The sales of marking machines are indeed a large number, and many manufacturers have aimed at them. Therefore, there will be a scene of contention among a hundred schools of thought for laser marking opportunities for a period of time.
