Causes
Obstacle hinders laser beam.
For LP-S series:
Lens cap has not been removed.
Distance to object is not appropriate.
For LP-M series:
The displacement sensor input does
not match the height of the actual
target object.
Object is not in place.
The laser marker is set for the marking
on flying objects despite the static
object.
Laser power is insufficient.
Laser wavelength is not appropriate for
material of objects.
When the marking mode is TEST:
The marking mode is "RUN".
When the marking mode is RUN:
The run mode is not started or the
marking trigger is not input.

Measures
Remove obstacle between head of laser marker
and object.
Remove lens cap.
Adjust distance between bottom surface of laser
maker and target surface of object as specified.
Confirm the displacement sensor and laser
marker input specifications and adjust the
displacement sensor output (analog current value)
to a suitable value.
Input the displacement sensor trigger when the
displacement sensor measurement value is
steady.
Match the displacement sensor measurement
position to the marking position.
Correct position of object. Guide indication feature
may be helpful for this purpose.
Set "Moving direction" to "STILL." on the Trigger
Setting screen.
• Increase laser power (including correction
factor).
• Decrease scan speed (including correction
factor).
Materials on which can be marked differ
depending on wavelength and output power of
laser marker.
Applicable marking object for FAYb laser marker
(LP-M / LP-S / LP-Z series):
Metal, resin (excluding transparent and
translucent types)
Select [TEST] of the marking mode.
Set the marking mode into [RUN] and press
