Obstacle hinders laser beam.
For LP-V / LP-W series:
Lens cap has not been removed.
Distance to object is not appropriate.
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:

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.
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 is as follows;
• FAYb laser marker (LP-V/LP-W series) : Metal,
resin (excluding transparent and translucent
types)
• CO laser marker (LP-400 series) : Resin
2
(including transparent and translucent types)
and paper.
Select [TEST] of the marking mode.
Set the marking mode into [RUN] and press
[Start].
Then, input the marking trigger from [TRIG. IN]
signal on the I/O terminal.
Check connections with external equipment for
mis-connection, disconnection or contact failure
due to any loose connector.
When the marking trigger is input from the I/O
terminal, check if marking trigger signal meets
write conditions.
• For Trigger Marking:
Check if one-shot signal of 10 ms or longer is
provided per marking cycle.
• For Equidistant Marking:
Check if status of the signal remains on during
marking.
