• Deactivate the seamless loop in the laser settings.
• If you want to radiate laser continuously without
any break, set the closed line by setting the start
and end points in the same position.
• Reduce the graphic size. The graphic width or
height should be less than 999.999 mm.
• If the "Graphic presets" is off, set on for "Adjustment
of size and filling" in the graphic object settings and
specify the graphic parameters in the "Marking
settings" screen.

laser marker is not exceeding the range of its
specification.

intake and exhaust port, and clean the air-cooling
part such as fan and filter.
• Turn ON TRIGGER IN after confirming READY
OUT is ON.

PROCESSING OUT is ON.
• Check the switch or the sensor connected to
TRIGGER IN of I/O terminal operates properly
