What should I do if the mixed carbon ribbon breaks or is damaged during the printing process?

When the mixed carbon ribbon breaks or is damaged during the printing process, the following measures can be taken to solve the problem:

1、 Check and adjust printer settings

Temperature and speed:

Reduce the printing temperature and depth to an appropriate range to minimize the risk of ribbon overheating.

Improve printing speed or paper output speed, and reduce the force time of carbon ribbon under frictional force.

Pressure and tension:

Check whether the tension of the carbon ribbon is uniform and avoid situations where it is too loose or too tight.

Adjust the pressure and balance settings of the print head to ensure the required low pressure for printing.

2、 Check the installation and usage status of the carbon ribbon

Installation method:

Reinstall the carbon ribbon and follow the manufacturer's instructions for proper installation.

Ensure that the carbon ribbon is properly wrapped around the machine without distortion or misalignment.

Usage status:

Check if the carbon ribbon is worn and replace it with a new one if necessary.

Avoid using expired or low-quality carbon ribbons.

3、 Cleaning and maintaining the printer

Clean the print head:

Regularly clean the print head and use specialized print head cleaning tools or clean cloths or cotton swabs to remove residue.

Prevent dust accumulation or foreign object impact caused by prolonged use of the print head without cleaning.

Maintain the printer:

Regularly check for foreign objects inside the printer, clean the print head and spindle.

Check if the paper guide is adjusted properly to ensure that the label paper and carbon tape are installed correctly.

Check if the printer's conveying components (such as rollers and conveyor belts) are functioning properly.

4、 Check and adjust printer accessories

Carbon ribbon axial tension:

Adjust the tension of the carbon ribbon supply shaft and recycling shaft to avoid excessive damping setting that may cause the carbon ribbon to break.

Slightly adjust the tension of the carbon belt shaft before and after to ensure synchronous operation of the carbon belt.

Paper pressure spring and paper limiter:

Adjust the paper pressure spring and paper limiter to ensure they are adjusted within the range of the label width.

5、 Other measures

Choose high-quality carbon ribbon:

Ensure that the film thickness and material of the carbon ribbon meet the technical requirements of the printer.

Choose a carbon ribbon that matches the type of label paper (such as wax based, mixed based, or resin based carbon ribbon).

Sensor cleaning:

Clean the sensor with compressed air or a small brush to ensure that the sensor can detect the carbon ribbon properly.

Contact professional maintenance personnel:

If the above methods are ineffective, it may be due to damage to internal parts of the printer. It is recommended to contact professional maintenance personnel for inspection and repair.

In summary, addressing the issue of breakage or damage to mixed carbon ribbons during printing requires multiple approaches, including adjusting printer settings, checking ribbon installation and usage status, cleaning and maintaining the printer, inspecting and adjusting printer accessories, and other measures. By comprehensively applying these methods, the problem of carbon ribbon fracture can be effectively solved, and printing quality and efficiency can be improved.
