TTO (Thermal Transfer Overprint) carbon belt in the printing process may encounter a variety of quality problems, in order to solve these problems, we can take a series of corresponding solutions. The following are some common TTO carbon belt quality problems and their corresponding solutions:
1. Carbon with needle eyes (bubbles)
Problem description: Needle holes or bubbles appear on the surface of the carbon belt, resulting in incomplete patterns or text when printing.Possible cause: The ink is not evenly coated on the carbon strip substrate.
The solution:
Choose a reliable supplier of TTO carbon tape to ensure uniform ink coating.
Carefully check the surface of the carbon strip before printing, if there are needle eyes or bubbles, it should be replaced in time.
2.the carbon belt wrinkles
Problem description: The carbon belt creases during use, affecting the printing effect.
Possible causes:
There was a problem with the tension control system during slitting.
The carbon tape does not wrap around the printer properly, or the width does not match the label.
The print temperature is too high or the print head pressure is set improperly.
The solution:
Adjust the printer's tension control system to ensure that the carbon strip remains flat during transmission.
Install the carbon strip correctly, make sure its width matches the label, and adjust the printer's pressure and temperature Settings appropriately.
3.carbon belt blank
Problem description: There is no ink in some areas of the carbon belt, resulting in missing printing content.
Possible cause: Improper treatment of the light film, so that the ink is not uniformly attached to the carbon strip substrate.
The solution:
Select the TTO carbon strip supplier with excellent processing technology to ensure that the light film is properly handled.
In case of blank carbon belt, replace the new carbon belt in time.
4. Paper core inner diameter tolerance problem
Description of the problem: the inner diameter of the paper core is too large or too small, resulting in the carbon belt can not be successfully loaded into the printer or the shaft can not be lifted.
Possible cause: Poor size control during manufacturing.
The solution:
Before purchasing, confirm that the paper core diameter of the carbon strip meets the requirements of the printer.
If the inner diameter does not match, try to adjust the printer's paper core holding device or replace the appropriate carbon tape.
5. Improper transportation and storage conditions
Description of the problem: Excessive temperature during transportation causes the carbon tape to stick together, or excessive humidity in the storage environment affects the performance of the carbon tape.
Possible causes: Improper temperature control during logistics transportation, or improper storage environment.
The solution:
Ensure that the carbon strip is protected from high temperatures and humidity during transportation and storage.
If the carbon tape is found sticking, try to gently separate and re-wind it, paying attention to keeping the carbon tape dry and clean.
6.paper core running side
Problem description: The edge of the paper core is not neat, resulting in the carbon belt is easy to break during use or the edge is not printed.
Possible cause: The precision of paper core processing in the manufacturing process is not enough.
The solution:
Choose the TTO carbon belt supplier with high machining accuracy.
If the paper core running problem, you can try to adjust the printer's paper core holding device or replace a new carbon strip.
7.the carbon belt length is not enough
Problem description: The actual length of the carbon belt is shorter than the marked length, which affects the use efficiency.
Possible cause: Inaccurate measurement or incorrect packaging marking during production.
The solution:
Confirm that the actual length of the carbon belt meets the demand before purchasing.
If you find that the length is insufficient, you can contact the supplier for return and replacement.
8.carbon belt processing problems
Description of the problem: The carbon tape is wrapped too tightly or too relaxed during processing, resulting in a good match with the printer during operation.
Possible cause: Improper slitting and winding process control.
The solution:
Select the TTO carbon belt supplier with stable processing technology.
If the operation is not smooth due to processing problems, you can try to adjust the carbon belt transmission mechanism of the printer or replace the new carbon belt.
