A Guide to Troubleshooting CO2 Lasers

The guide covers common problems with CO2 laser markers, including insufficient laser power, equipment shutdowns, and misalignment, and provides practical solutions, such as cleaning lenses, calibrating the galvanometer, and maintaining the cooling system, to help users quickly identify problems and master daily maintenance techniques, thereby extending the life of the equipment.

Why is the laser marking effect getting worse?

If the markings are blurred or too shallow, don't panic immediately.First, check whether the laser power is normal. Insufficient power is usually caused by a dirty or aged lens.Take off the dust cover and use a clean cloth dipped in alcohol to gently wipe the focusing lens and the reflecting lens.If this doesn't work, it's probably time to contact the factory and replace the laser tube.

What if the equipment suddenly stops working?

When a machine suddenly fails to work, check the power supply and cooling system first.Loose power cords or blocked cooling fans can cause equipment to shut down as a protective measure.If this problem occurs repeatedly, it may be a problem with the motherboard or power supply, and will require professional repair.

Is the labeling always off?

If the laser is marking in the wrong place, then the problem is probably with the galvanometer or the drive mechanism.If a problem is found, the first thing to do is to check the software's coordinate parameters to see if they were entered incorrectly.If the screws are loose, the light path will be off, and a red light can be used to help calibrate.After adjusting, be sure to print on scrap paper several times to confirm that the adjustment is stable before using it formally.

The equipment makes a lot of noise when it's working.

If the machine makes an unusual noise, stop it and open the case to check whether anything is stuck in the tracks or belts.Lack of oil in the tracks can also cause squeaking; the problem can be solved by applying the special lubricant.If a motor is making a regular noise, it may be that the current to the drive is not stable, and the parameters need to be reset or a part needs to be replaced.

Never slack off on maintenance.

To reduce the rate of failure, the optical system should be cleaned at least once a week, and the cooling water (for water-cooled lasers) should be checked monthly.When it is hot in summer, make sure the temperature in the environment doesn't go over 35 ° C, otherwise the laser tube will overheat.If your computer suddenly freezes up while you are working on a program, remember to regularly clean out your temporary files. Don't let your computer work sick.
