When human beings have experienced disasters, we know that life and health are so precious.

of human survival.
• Benefits of Oxygen:
Inhalation of oxygen can improve the level of arterial blood oxygen partial pressure and oxygen
saturation of the body, in addition to promote the metabolism of the body, and is also one of the very
important methods for auxiliary treatment of a variety of diseases. Oxygen inhalation can make the
oxygen in the human tissue more abundant, cells will get sufficient oxygen supply after the
metabolism will be more active, normal people will have a refreshed, memory improved, spirit feeling.
Patients with chronic heart and lung diseases, long-term oxygen inhalation can delay the aggravation
of the disease, at the same time, but also can relieve the symptoms of chest tightness, wheezing and
dyspnea of patients. Especially when working under great pressure, they are prone to dizziness,
Reasons and solutions for the unclear coding of laser printers
Reasons and solutions for the unclear coding of laser printers
Many manufacturers who use laser printers will definitely encounter when the code is not clear, so what is the situation? Let's take a look today!
First of all, we must understand the main structural components of laser printers, including laser tubes, polarizer systems, power controllers, and software operating systems. As the use time increases, the laser tube will decay with the increase of the amount of luminescence, and it will encounter the problem we mentioned above. The printing effect is not clear and it feels very weak.
How to deal with it? If it is a CO2 carbon dioxide laser machine, according to the time of use, manufacturers generally recommend a laser tube inflation plan such as 2 years or 3 years; if the use time is short, the mark is not clear within 1 year, then you can Increasing the power, or lowering the scribing speed, increasing the power of the laser tube is a relatively common treatment.
2, the marking effect is uneven, deep and shallow.
This situation is also quite common. We have said that the working principle of the laser machine is to emit laser light through a laser tube, deflect it through a polarizer system, and burn it on the surface of the product to form physical and chemical reactions to form characters.
There is a deep and shallow, here we should pay attention to the focus point, that is, the adjustment of the focal length, K series, F series laser machine has the function of red light positioning focus, you can click, two red light, red light When you get together, it is when the focal length is good, and you can achieve a clearer print on the surface of the product.
Generally, laser jet printers have such a situation. When there is no experience, it is recommended to consult the manufacturer. Compared with the traditional inkjet code printer, the laser printer has a very low failure rate, especially the hardware configuration is very good. Chengdu Weican, who has many years of service experience and well-known brand products, is very recommended to buy.
