1. All marked characters have ghosts

Reasons and treatment methods:

Check whether the lens is loose and tighten it; check whether the lens is stained, and clean the lens.

2. In the same type of engraving, the front is not blurred, but the back is blurred

Reasons and treatment methods:

The light path is shifted. Just adjust it, let the manufacturer give you instructions.

3. The typed characters are deformed or have double images

Reasons and solutions: the product positioning is not stable (not stable or too loose), or the product or machine is touched while marking. Position the product and do not touch the product being marked and the equipment that is working.

In addition to the three main reasons mentioned above, the marking speed is too fast, some parts of the equipment are too loose or too tight, or there are problems, etc., which may cause deformation or ghosting of the marked font.

If you encounter equipment problems that cannot be solved by yourself, it is recommended that you contact the equipment vendor or consult the customer service of Fulan Laser
