What are the common problems in the use of TTO carbon belt?

The common problems in the use of TTO carbon tape (thermal transfer carbon tape) mainly include the following aspects:

1. Carbon band wrinkle or print wrinkle

The reason:

The carbon tape is not properly wrapped around the machine.

The width of the carbon tape does not match the label, and either too large or too small may cause the print to wrinkle.

The pressure and balance Settings of the print head are not correct, and the pressure is unbalanced on the left and right sides.

The solution:

Re-install the carbon tape correctly and ensure that the carbon tape is smoothly wrapped around the machine.

Adjust the width of the carbon belt. It is generally recommended that the width of the carbon belt be 10mm larger than the label to save material and avoid rubbing the print head on the edge of the carbon belt.

Adjust the pressure and balance of the print head to ensure that the pressure is balanced on the left and right sides.

2. Carbon with needle eyes (bubbles)

Reason: the ink is not coated in the coating process.

Solution: Replace the qualified carbon belt to ensure the uniform ink layer.

3. Carbon belt fracture

The reason:

The carbon belt tension is too large, pulling the suture line or breaking the color belt during the printing process.

The carbon belt is wrapped too tightly or loosely during processing, resulting in the inability to match with the printer during operation.

The solution:

Cut off the broken part and sew it back together (if it is broken by a suture).

Replace the new carbon belt to ensure the processing quality of the carbon belt.

Adjust the winding tightness of the carbon tape to meet the requirements of the printer.

4. The carbon belt is stuck

Reason: the edge of the carbon belt is silky and easily entangled in the ribbon wheel after fuzz.

Solution: Open the printer cover, open the ribbon swivel arm and hammer interlock handle, gently pull back the ribbon, then close the ribbon swivel arm and hammer interlock handle, and restart the printer.

5. The carbon strip is adhered to the medium

Reason: The printing temperature is too high or the carbon strip is incompatible with the medium.

Solution: Reduce the printing temperature or replace the carbon belt compatible with the medium.

6. The print effect is not clear

The reason:

The quality of the carbon belt is not good, and the ink layer is not uniform.

Print heads are dirty or worn.

Improper printer Settings, such as temperature, pressure and other parameters set unreasonable.

The solution:

Replace the quality carbon strip.

Clean print heads and rollers to ensure they are free of dust and impurities.

Adjust the printer Settings, such as temperature, pressure, etc., to get the best print results.

7. Carbon belt transportation and storage problems

Problem: High temperature during transportation leads to adhesion of carbon tape; Improper storage environment leads to aging of carbon belt.

The solution:

Ensure that the carbon strip is in the appropriate temperature and humidity conditions during transportation.

When storing carbon belts, choose a dry, cool place to avoid direct sunlight and high temperature and humidity environment.

To sum up, TTO carbon belt may encounter a variety of problems during use, but through the correct installation, adjustment and maintenance measures, these problems can be effectively avoided. At the same time, the choice of reliable quality carbon belt suppliers and printer manufacturers is also an important factor to ensure the printing effect.
