How to Fix the Problem of Duplicate Serial Numbers
The laser marking system can also be used to mark serial numbers, which can help prevent production confusion and data errors.From a practical perspective, it explains how to check software settings, hardware conditions, and system synchronization, and provides suggestions on maintenance, helping users quickly solve problems with duplicate serial numbers and ensuring smooth production.
Why are there duplicate serial numbers?
If you encounter a problem with duplicate serial numbers, don't panic. Most of the time the problem is with software settings or equipment state.For example, the serial number rules in the software might not have been set properly, or the printer might have jammed and printed the same number twice.Another possibility is that when several devices use a common database, they may "fight" over a number, and as a result the numbers collide.
The problem is traced step by step to its source.
Check the software settings.
First open the control software and check to see if the rule for automatically creating serial numbers is selected.One customer even ended up calling the same number 100 times in a row because of a mistake in selecting the "fixed value" option.Finally, check the initial values and step sizes of the counters, so that production isn't delayed by a simple numerical error.
Testing the hardware.
In manual mode, test the marking head independently to check whether the trigger signal is normal.If you encounter a situation where the laser head responds slowly, causing the laser to "fire twice," you may need to clean the optical path or restart the controller.Make sure that the USB cable is firmly connected.
A system of checks and balances.
If it is a networked multi-computer collaborative mode, you must check the time synchronization and database connection status.In one incident, a factory's master control computer had a time error, causing three machines to simultaneously generate the same serial number.It is recommended that servers be regularly synchronized.
Preventive maintenance is the best policy.
It is a habit that should be cultivated, like the way an experienced driver will walk around his car to check it over before driving off.Regularly back up the parameter settings, and when upgrading software, pay particular attention to version compatibility.If you encounter a problem where the serial number rules are reset after an upgrade, a backup can save you a lot of trouble!
What do you do when faced with a difficult case?
If you have tried everything and it still doesn't work, don't push it. Take a snapshot of your current parameters, then restore factory settings and test basic functions.If there is still a problem, the motherboard counter may be defective, and the customer should call the manufacturer at this point.Remember, the longer the problem is allowed to drag on, the greater the losses.
