Thermal cash register paper is widely used in supermarkets, catering, retail and other industries. It is favored for its advantages such as fast printing speed and no need for carbon ribbon. However, in actual use, users may encounter some problems that affect the printing effect or equipment operation. This article will introduce the common problems of thermal cash register paper and the corresponding solutions to help users better use and maintain it.
1. The printed content is not clear or fades quickly
Problem causes:
Thermal paper is of poor quality and the coating is uneven or poor quality.
Aging or contamination of the print head leads to uneven heat transfer.
Environmental factors (high temperature, direct sunlight, humidity) cause the thermal coating to fail.
Solution:
Choose thermal paper from a regular brand to ensure the quality of the coating.
Clean the print head regularly to avoid dust accumulation that affects the printing effect.
Avoid exposing the cash register paper to sunlight or high temperature environments and store it in a cool and dry place.
2. Blank bars or broken characters appear when printing
Problem cause:
The print head is partially damaged or dirty, resulting in partial heat transfer failure.
The thermal paper roll is not installed properly, and the paper is not properly attached to the print head.
Solution:
Clean the print head with alcohol cotton to remove stains or toner residue.
Check whether the paper roll is installed correctly and ensure that the paper is flat and wrinkle-free.
If the print head is seriously damaged, contact after-sales for replacement.
3. The paper is stuck or cannot be fed
Problem cause:
The paper roll is installed in the wrong direction or the size does not match.
The paper roll is too tight or sticky due to moisture.
Solution:
Confirm whether the paper roll direction (thermal side facing the print head) and size meet the printer requirements.
Adjust the tightness of the paper roll to avoid paper jams caused by excessive tightness.
Replace the damp or sticky paper roll.
4. The handwriting gradually disappears after printing
Problem cause:
Poor-quality thermal paper is used, and the coating stability is poor.
Long-term exposure to high temperature, strong light or chemical environment.
Solution:
Purchase high-stability thermal paper, such as “long-lasting preservation” products.
It is recommended to copy or scan important bills for archiving to avoid long-term exposure to adverse environments.
5. The printer reports an error or cannot recognize the paper
Problem cause:
The paper sensor is faulty or does not detect the paper correctly.
The outer diameter of the paper roll is too large or too small, which exceeds the printer’s support range.
Solution:
Check whether the sensor is blocked or damaged, clean or adjust the position.
Replace the paper roll that meets the specifications to ensure compatibility with the printer.
Summary
Thermal cash register paper may encounter problems such as blurred printing, paper jams, and fading during use, but in most cases, it can be solved by choosing high-quality paper, correctly installing, and regularly maintaining the printing equipment. Reasonable storage of thermal paper and paying attention to environmental factors can effectively extend its service life and ensure stable printing quality.
