Is It Worth Buying a Used Laser Marker?

Second-hand lasers have a clear price advantage, but when purchasing one you should pay special attention to the laser, control system, and cooling system.We'll share practical testing techniques with you, helping you to avoid the risk of "falling into a trap" and to easily judge whether a piece of equipment is worth buying.

Is it worthwhile to buy a second-hand laser marker?

Many friends want to get into the business, but the high cost of new equipment has made them hesitate.Although second-hand equipment is half the price or even less, there is always the worry of buying a problem machine.I feel that if one's budget is limited, second-hand equipment is still worth considering, but the key is to learn how to judge the actual condition of the equipment.

The three types of problems are the main targets of the test.

According to experienced repairmen, the three most common problems with secondhand equipment are as follows.When we check it ourselves, all we need is a marking pen and a flashlight from our cell phone.

The aging of the laser.

First, check the number of hours the machine has been in use. This can usually be found in the system menu.If the laser has been in use for more than 8,000 hours, then you should be careful, as the efficiency of the laser tube may have decreased by 30 % or more.If the lines are fuzzy or the colors uneven, there's an 80 % chance that the laser is wearing out.

The stability of the control board card.

After turning on the device, switch it on and off three times, and observe whether the screen becomes distorted or the device freezes during each boot-up.The key is to look at the reaction speed of the graphics software. If the computer freezes up every time it has to load a complex graphic, then there might be a problem with the card.But don't buy a machine with a hot heat sink.

Is the water-cooling system leaking?

First, check the radiator for white scale deposits, then feel the water pipes for any sticky residue, which is a sign of leakage.The most direct test method is to run the equipment for two hours straight. If the water temperature exceeds 35 ° C and continues to rise, it means that the cooling system may be clogged or the water pump is not powerful enough.

Don't neglect these details.

The wear on the guides is directly related to marking precision, so if the surface has a noticeable scratch when you run your fingernail across it, it's best to abandon it.The lens must also be checked for scratches, which will gradually degrade the marking effect.Finally, make sure the seller demonstrates the equipment in person, and record the demonstration on video.

Buying secondhand equipment is like opening a blind box, but if you follow the above advice and carefully inspect the machines, there's a good chance you'll get a reliable machine for a small price.If you find a "nearly new" machine at a particularly low price, you should be wary. After all, you can't get something for nothing.
