Symptom Causes/Measures
Poor marking quality. • Check for product or laser vibration.
• Has the product been changed (e.g. di-
mensions, material)?
• Check the lens. Clean it if necessary.
• Check the working distance.
• Check the parameter set (power too low,
speed to high).
• Check the product (must be free from dirt,
water, dust, oil, etc.).
• Check the fume extractor (must be on and
suitable for the application).
• Check the encoder. If it is slipping increase
the tension of the encoder wheel.
Laser stops due to overtempera-
ture.
