The common faults and solutions of double-sided labeling machines are as follows:

1. Label detachment or inaccurate labeling:

Reason: Unstable supply of labels, incorrect placement of sticker heads, poor quality of label rolls, etc.

Solution: Check the label supply system, adjust the position of the sticker head, replace the label roll, or adjust the parameters.

2. Tag stuck:

Reason: Label curling, conveyor belt malfunction, etc.

Solution: Check the label roll, inspect the conveyor belt, and remove any stuck labels.

3. The label roll is unstable:

Reason: Improper tightness of the label roll, loose core, etc.

Solution: Adjust the tension of the label roll to ensure that the core is securely fastened.

4. Sensor malfunction:

Reason: dirty sensor, improper adjustment, etc.

Solution: Clean the sensor, adjust its position, and ensure that it is working properly.

5. Mechanical malfunction:

Reason: Mechanical components are damaged or loose.

Solution: Check the mechanical components to ensure that there are no damaged or loose parts.

6. Electronic malfunction:

Reason: Control system malfunction.

Solution: Check the electronic components and connecting wires to ensure the normal operation of the electronic system.

7. Wear of sticker head:

Reason: Long term use leads to wear and tear.

Solution: Regularly check the sticker head and replace it promptly if it is worn.

8. Power issue:

Reason: Unstable power supply.

Solution: Ensure a stable power supply and avoid voltage fluctuations.

9. Operation error:
