What problems are prone to occur during the printing process of three proof thermal paper?

The problems that are prone to occur during the printing process of three proof thermal paper mainly include the following aspects:

1、 Printing is not clear

Quality issues with thermal paper: If the quality of thermal paper is poor and the ink penetration is uneven, it can cause blurry printed text. Therefore, when choosing, one should choose high-quality and durable three proof thermal paper.

Insufficient printing temperature: Thermal printers require a certain temperature to fully melt and penetrate the ink into the paper. If the temperature is not sufficient, the ink cannot fully penetrate, which will result in unclear printing. At this point, you can adjust the temperature setting of the printer or check if the print head is working properly.

Aging or clogging of print heads: Prolonged use or clogging of print heads can affect ink ejection, resulting in poor printing performance. Therefore, it is necessary to regularly inspect and clean the print head to ensure its cleanliness and normal operation.

Printing speed too fast: In the case of printing speed too fast, ink may not have enough time to fully penetrate the paper, which can also lead to unclear printing. At this point, the printing speed can be reduced to achieve better printing quality.

Improper printing density setting: If the density set during printing is not appropriate, it can also affect the printing effect. The printing density should be set to the optimal value based on the printer model and paper type.

2、 Printing content fades

Improper storage of thermal paper: If thermal paper is exposed to high temperatures, direct sunlight, or humid environments for a long time, the printed content is prone to fading. Therefore, the printed thermal label paper should be placed in a dark, cool, and dry place, away from heat sources and chemicals.

Using incompatible ink or ribbon: Some ink or ribbon may react with the coating of the three proof thermal paper, causing the printed content to fade. Therefore, when choosing ink or carbon ribbon, it should be ensured that they are compatible with three proof thermal paper.

3、 Paper stuttering or incomplete printing

Uneven paper quality: If the quality of thermal paper is uneven, it may cause paper to jam or incomplete printing during the printing process. At this point, the quality of the paper should be checked and replaced with paper of uniform quality.

Improper printer settings: The paper type, size, and other settings of the printer do not match the actual thermal paper used, which may also cause printing problems. Therefore, before printing, it is important to ensure that the printer settings match the actual paper used.

4、 Other common questions

Print head damage: If the print head is damaged, it will not be able to spray ink properly, resulting in printing failure. At this point, it is necessary to replace the damaged print head.

Sensor malfunction: The printer's sensor is responsible for detecting the position and status of the paper. If the sensor malfunctions, it may cause the paper to not feed correctly or the printing position to be offset. At this point, it is necessary to check and repair the sensor malfunction.

In summary, the common problems that three proof thermal paper is prone to during the printing process include unclear printing, fading of printed content, paper jamming or incomplete printing, as well as other common issues such as damaged print heads and sensor failures. To avoid these problems, it is necessary to choose high-quality thermal paper, set printer parameters correctly, regularly inspect and clean printing equipment, and properly store and use thermal paper.
