Marking
Troubles
Causes
Measures
Marking cannot be done.
(Even though the laser
radiation indicator
changes to the marking
status, nothing marked
on the object.)
Obstacle hinders laser beam.
Remove obstacle between head of laser marker
and object.
For LP-V / LP-W series:
Lens cap has not been removed.
Remove lens cap.
Distance to object is not appropriate.
Adjust distance between bottom surface of laser
maker and target surface of object as specified.
Object is not in place.
Correct position of object. Guide indication feature
may be helpful for this purpose.
The laser marker is set for the marking
on flying objects despite the static
object.
Set “Moving direction” to “STILL.” on the Trigger
Setting screen.
Laser power is insufficient.
•
Increase laser power (including correction
factor).
•
Decrease scan speed (including correction
factor).
Laser wavelength is not appropriate for
material of objects.
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
2
laser marker (LP-400 series) : Resin
(including transparent and translucent types)
and paper.
Marking cannot be done.
(The laser radiation
indicator does not
change to the marking
status.)
When the marking mode is TEST:
The marking mode is “RUN”.
Select [TEST] of the marking mode.
When the marking mode is RUN:
The run mode is not started or the
marking trigger is not input.
Set the marking mode into [RUN] and press
[Start].
Then, input the marking trigger from [TRIG. IN]
signal on the I/O terminal.
When the laser marker is under the
remote mode or run mode:
Marking trigger signal is not input.
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.
