Causes and solutions of blank or light phenomenon in wax-based carbon strip printing

The reasons and solutions for the blank or light phenomenon of wax-based carbon strip printing can be summarized as follows:

First, reason analysis

1. Carbon strip quality issues:

Low quality or expired carbon strips may result in a light or blank print color. The uneven wax layer on the surface of the carbon strip or the unstable quality may affect the printing effect.

2. Printer setup problem:

The printer's print quality Settings may be too low, or the print temperature and concentration may not be adjusted to a level suitable for wax-based carbon strips. In addition, printing too fast may also cause the wax layer of the carbon strip to not sufficiently transfer to the label paper.

3. Print head problem:

The accumulation of dust, grease and other substances on the printing head may affect the contact between the carbon belt and the label paper, resulting in poor printing results. At the same time, aging or damage to the print head may also lead to blank or light printing.

4. Carbon tape is not compatible with label paper:

Wax-based carbon strips may not be suitable for certain types of label paper, such as materials with smooth surfaces (such as PET), because wax-based carbon strips have weaker adhesion to these materials.

5. Improper installation and use of carbon belt:

The carbon tape is not properly wrapped around the machine, or the surface of the carbon tape has wrinkles, bubbles and other defects, can lead to blank or light printing.

6. Environmental factors:

Dust, temperature, humidity, etc. in the printing environment may also have an impact on the printing effect. For example, dust falling into the printer may cause the print head to not transfer the toner to the label paper well.

Second, solutions

1. Replace high quality carbon belt:

Choose a reputable supplier and purchase new, high quality wax-based carbon strips. Ensure that the carbon strip is used within the expiration date and avoid using expired carbon strips.

2. Adjust printer Settings:

Improve your printer's print quality Settings, including print temperature, concentration, and speed. Make appropriate adjustments according to the specific requirements of the wax based carbon tape and the material of the label paper.

3. Clean print head:

Clean the print head regularly with a professional print head cleaning solution to remove accumulated dust and grease. Keep the print head surface clean to improve printing results.

4. Select the right label paper:

Select the appropriate label paper material according to the printing requirements. For applications that require higher adhesion, consider using resin-based carbon tape or other more suitable label paper.

5. Proper installation and use of carbon belts:

Ensure that the carbon belt is properly wrapped around the machine to avoid wrinkles, bubbles and other defects. When installing the carbon strip, be careful to make the carbon surface of the carbon strip contact the outer surface of the printing paper.

6. Improve the printing environment:

Keep the printing environment clean and reduce the impact of pollutants such as dust. At the same time, pay attention to controlling the temperature and humidity of the printing environment to obtain the best printing effect.

In summary, the causes and solutions for the blank or shallow phenomenon of wax-based carbon tape printing involve many aspects, including the quality of carbon tape, printer Settings, print head status, the compatibility of carbon tape and label paper, and environmental factors. By checking and dealing with these problems one by one, the printing effect of wax-based carbon tape can be effectively improved.
