versa.
• Check that the power is not too low for marking.
• Check that the marking speed and the pulse repetition frequency are appropriate
to the materials used.
• Check the electrical connections and the condition of the optical fiber.
• Check that the optical fiber is not curved into a radius of less than 90 mm
(3.543 in).
