How should the printing pressure of wax-based carbon tape be adjusted?

The adjustment of the printing pressure of the wax based carbon strip is very important to ensure the print quality and extend the service life of the print head and the carbon strip. The following are some methods and steps to adjust the printing pressure of wax based carbon tape:

First, understand the impact of printing pressure

The printing pressure directly affects the contact tightness between the print head and the carbon strip and the label paper, which affects the clarity of the print, the ink layer transfer effect and the wear of the print head. The proper printing pressure ensures that the ink layer is evenly transferred to the label paper, avoiding problems such as blurring, broken lines, or excessive wear of the print head.

Second, printing pressure adjustment method

1. Use pressure regulating devices

Most barcode label printers are equipped with pressure adjustment devices, through which the user can adjust the pressure of the print head. The specific steps are as follows:

Locate the pressure regulator: First, you need to find the pressure regulator on the printer. These devices may be located above or to the side of the print head bracket and may be in the form of knobs, screws, or other adjustable parts.

Adjust the pressure: Gently rotate or adjust the pressure regulator using a randomly distributed tool such as an Allen wrench. In general, a clockwise rotation increases the pressure and a counterclockwise rotation decreases it. When adjusting, it should be carried out gradually, and a printing test should be carried out after each adjustment to observe the change of the printing effect.

2. Adjust left and right pressure balance

In addition to the overall pressure, it is also necessary to pay attention to the pressure balance on the left and right sides of the print head. The pressure imbalance between the left and right may cause the printing effect to be clear on one side and blurred on the other. The method of adjusting the right and left pressure balance varies depending on the printer model, but general steps include:

Loosen the fixing screws: Loosen the fixing screws on the left and right pressure regulating assemblies using the distributed tool.

Move the regulating assembly: Gently move the left and right pressure regulating assembly to the appropriate position as required. Moving in the left direction usually increases the pressure on the left side of the print head and decreases the pressure on the right side; And vice versa.

Tighten the fixing screws: After adjusting them, use a tool to tighten the fixing screws and secure the left and right pressure adjustment components.

Third, precautions

Gradual adjustment: When adjusting the printing pressure, it should be carried out gradually to avoid sharp changes in print quality or damage to the print head caused by excessive one-time adjustment.

Regular cleaning: Before and after adjusting the printing pressure, it is recommended to clean the print head to remove impurities such as dust and toner to ensure print quality and the life of the print head.

Refer to the instructions: Different models of barcode label printers may vary in terms of printing pressure adjustment. Therefore, before making adjustments, you should carefully read the instruction manual of the printer to understand the specific adjustment methods and precautions.

Fourth, summary

The adjustment of printing pressure of wax-based carbon tape is an important link to ensure printing quality and extend the service life of printing head and carbon tape. Through the rational use of the pressure adjustment device and the adjustment of the left and right pressure balance, you can obtain a clear print effect and reduce the wear of the print head. At the same time, regular cleaning of the print head and following the printer's instructions are also key steps to ensure print quality.
