If the laser coder has a duplicate number problem, the cause can be found and solved from the software, hardware and operation aspects. The specific methods are as follows:

Software settings
Check coding settings: Check coding rules, counters and other settings in the coding software to ensure that there are no duplicate coding instructions or wrong settings. If the correct method such as fixed coding is set instead of increment, duplicate numbers will be caused, and the coding rules need to be set again as required.
Update software version: The software is vulnerable or incompatible with the system may also cause this problem. You can contact the manufacturer to obtain the latest version installation update and fix possible problems.
Hardware equipment
Check the laser head: If the laser head is faulty, it may affect the normal operation of coding. It is necessary to check whether it is working normally, whether it is loose, damaged, etc. If there is a problem, professional personnel need to repair or replace it.
- Cleaning the optical path system: If there is dust, debris, etc. in the optical path system, it will interfere with laser transmission and focusing, causing abnormalities in coding. Use a special cleaning tool to clean it carefully.
- Troubleshooting the control system: Control system failures will also cause duplicate numbers to be printed. Check the control board, connecting wires, etc. to see if there are any problems such as looseness and short circuits. If so, relevant parts need to be repaired or replaced.
Operation and use aspects
Confirm the operating process: Use the printer strictly in accordance with the correct operating process to avoid erroneous operation. For example, improper restart or interruption during the coding process may cause coding errors, and standardized operations are required.
- Verify workpiece placement: If the workpiece is not placed firmly or the position is inaccurate, it may cause the same position to be coded repeatedly. Make sure that the workpiece is placed smoothly and in the correct position in the coding area.
