In view of the electrostatic adsorption problem encountered in the printing of TTO (thermal transfer printing) high-speed coding carbon tape, the following measures can be taken to solve it:


1. Control ambient humidity

Maintain proper humidity: The generation of static electricity is closely related to the ambient humidity. It is usually recommended to operate in the humidity range of 40%-60%, which helps to reduce the generation of static electricity. You can adjust the humidity of the printing environment by using a device such as a humidifier.

2. Use antistatic materials

The selection of antistatic carbon strip: The selection of carbon strip with antistatic coating can effectively reduce the generation and accumulation of static electricity. These carbon bands add an antistatic component to the surface, balancing the charge and reducing electrostatic adsorption.

Use antistatic label paper: Similarly, the selection of antistatic label paper can also reduce static problems to a certain extent. Ensure the compatibility of carbon tape and label paper for the best printing results.

3. grounding treatment

Connect the equipment to the ground: Connect the TTO high-speed coding machine to the ground through the ground wire to ensure that the equipment is in a good grounding state. In this way, the static electricity generated during the running of the device can be released to the ground in time to prevent the accumulation of static electricity from affecting the printing process.

4. Regular cleaning and maintenance

Clean print heads and rollers: Clean print heads and rollers regularly with cleaning tools such as industrial alcohol and cotton to remove dust and impurities and keep their surfaces clean. This helps to reduce the possibility of electrostatic adsorption on the print head and roller.

Check the carbon belt transmission system: ensure that the carbon belt transmission system is smooth and avoid electrostatic problems caused by too much or too small carbon belt tension.

5. Optimize the printing process

Adjust printing parameters: According to the specific printing needs and media characteristics, reasonable setting of printing temperature, speed and pressure parameters. Avoid excessive printing temperature resulting in electrostatic increase, but also to ensure the stability and consistency of printing speed and pressure.

Control the distance between the carbon strip and the print head: Adjust the distance between the carbon strip and the print head properly to reduce the electrostatic adsorption caused by too close a distance.

6. increase the electrostatic elimination device

Installing static removal rods: During the printing process, static removal devices such as ion fans or static removal rods can be added to the carbon strip transmission path. These devices are able to generate an electric charge opposite to static electricity, thereby neutralizing static electricity on the carbon belt and reducing static adsorption problems.

7. Other precautions

Avoid materials that generate static electricity: When selecting printing media and auxiliary materials, materials that generate static electricity should be avoided as far as possible to reduce the occurrence of static electricity problems.

Regular inspection and replacement of accessories: Regular inspection and replacement of aging print heads, rollers and other accessories to ensure that the equipment is in good working condition, but also to help reduce static problems.


In summary, by controlling the ambient humidity, using antistatic materials, grounding treatment, regular cleaning and maintenance, optimizing the printing process and adding static elimination devices, the static adsorption problem of TTO high-speed coding carbon tape in printing can be effectively solved.
