Troubles Causes Measures
Marking cannot be done.
(The laser radiation
indicator does not
change to the marking
status.)
When the laser marker is under the
remote mode or run mode:
Next marking trigger signal is entered
before completion of current marking
cycle.
(E800 occurs.)
Enter next marking trigger signal after making
sure that READY output is on.
When the laser marker is under the
remote mode:
Marking trigger is input when the
READY output is OFF status.
Refer to “READY signal is not turned to ON” in
the External Control Troubleshooting.

Marking quality
Troubles Causes Measures
Marking fades entirely/
partially.
Laser emission port is not clean.
Refer to Operation/Maintenance Manual and
clean contaminants off the laser emission port.
If contaminants persist, replace lens and/or laser
emission port protection glass (for LP-V/LP-W
series only). Contact our sales office.
Fumes occurring during marking hinder
laser beam.
Install dust collector.
Check that dust collector works well.
Distance to object is not appropriate.
Adjust distance between bottom surface of laser
maker and target surface of object.
Target surface of object is inclined.
Make adjustment so that bottom surface of laser
marker head and target surface of object are
parallel with each other.
There are variations in properties of
objects.
• Object thickness
• Distance to object
• Object surface condition (including
roughness, gloss level, etc.)
• Object material (including chemical
composition ratio)
Adjust marking conditions according to variations
found.
Object feeder is not stable.
Adjust object feeder so that position of objects
become stable.
Performance of laser oscillator
deteriorates due to aging.
• Increase laser power setting.
• Decrease scan speed.
If initial marking quality cannot be reached even
if laser power is set to the upper limit, laser
oscillator must be replaced. Contact our sales
office.
