Why can't the thermal printer paper print out

Time : 2022-11-01 Hits : 7

Thermal printer paper is very common in our daily life, and it is not unfamiliar to us. Now no matter in schools, companies, or even families, printers are indispensable, and thermal printer paper plays a very important role in our lives. It is deeply loved by the majority of friends. However, in our daily life, we will encounter some problems more or less. If we can't solve them in time, it may have a great impact. Next, we will introduce the problems of thermal printer paper that cannot develop color. related question.

The working principle of the thermal receipt printer is that a semiconductor heating element is installed on the print head. After the print head is heated and contacts the thermal printer paper, the required pattern can be printed. The principle is similar to that of a thermal fax machine. The image is created by heating, which produces a chemical reaction in the film. This thermal receipt printer chemical reaction is carried out at a certain temperature. High temperatures accelerate this chemical reaction. When the temperature is lower than 60°C, the paper takes a considerable time, even several years, to become dark; when the temperature is 200°C, this reaction will be completed within a few microseconds.

There are generally two reasons for the thermal receipt printer to print no color

One is caused by the wear of the print head. Generally, the print head has a length of 50km and 100km.

Second, the thermal printer paper roll used for printing is of poor quality and uneven coating, and better thermal printer paper roll can be replaced

Generally, thermal receipt printers can adjust the printing density. For your problem, you can increase the printing density, and the color of the printed words will become darker.

This kind of problem is very common in the usual use of thermal receipt printers. Generally speaking, this situation is mainly related to hardware failures. When encountering such problems, you should generally pay attention to some key parts of the thermal receipt printer. Here we take an inkjet printer as an example. When the color of the printed product is blurred and the font is not clear, the fault can be locked in the print head, and the print head can be automatically cleaned by the machine. Wipe the area close to the print head with a strong paper; if the above method still does not solve the problem, the only thing to do is to reinstall the printer driver.
