What causes ghosting of text printed on wax-based carbon tape?

The characters printed on wax-based carbon tape appear double, which may be caused by many factors. Here are some of the main reasons and their explanations:

1. Print head problem

Print head dirt: After long-term use, the surface of the print head may accumulate ink, dust or debris and other dirty dirt, which will affect the uniform deposition of toner, resulting in the printing text appears double.

Print head damage or aging: The heating element or nozzle inside the print head may be damaged or aging due to long-term use, and the distribution of toner cannot be controlled normally, which will also cause ginning.

2. The temperature is set improperly

Print temperature is too low: If the printer's temperature setting is too low, the wax-based carbon strip may not be able to melt sufficiently, resulting in uneven distribution of toner on the medium and the formation of ghosting.

Temperature fluctuation: The unstable fluctuation of temperature during the printing process may also affect the melting state of the toner, resulting in inconsistent printing effects and double shadows.

3. The carbon belt does not match the printing medium

The type of carbon tape is not suitable: Different printing media (such as paper, film, etc.) have different requirements for carbon tape. If the wax based carbon tape used does not match the printing medium, it may lead to insufficient adhesion of the toner on the medium and double shadow.

Surface characteristics of the medium: the surface smoothness of the medium, ink absorption and other characteristics will also affect the printing effect. If the surface of the medium is too smooth or the ink absorption is poor, the toner may not be uniformly attached, forming a double shadow.

4. Printer mechanical parts problem

Loose or worn transmission parts: If the transmission parts (such as gears, belts, etc.) inside the printer are loose or worn, the position of the carbon belt may be offset during transmission, which affects the printing effect and produces gelling.

Uneven press spring: The uneven pressure of the press spring may also lead to the contact between the carbon strip and the medium is not tight, and then affect the uniform distribution and adhesion of the toner, resulting in double shadow.

5. Other factors

Poor quality of carbon tape: there are uneven quality carbon tape products on the market, and some poor quality carbon tape may have problems such as uneven toner distribution and poor adhesion during use, resulting in gelling of printed text.

Environmental factors: Conditions such as temperature and humidity of the printing environment may also have an impact on the printing effect. For example, high humidity may cause toner on the carbon strip to clump or stick easily, affecting the print quality.

In view of the above reasons, the following measures can be taken to solve the problem of ghost of wax-based carbon tape printing text:

Clean the print head regularly to keep its surface clean and free of dirt.

Adjust the appropriate printing temperature according to the printing medium and carbon strip type.

Make sure the carbon strip matches the printing medium and select the appropriate type of carbon strip.

Check and adjust the mechanical parts of the printer to ensure that they are in good condition.

Use reliable carbon belt products and avoid using inferior carbon belts.

Control the temperature and humidity of the printing environment to keep it relatively stable.
