Troubles Causes Measures
The filling lines in the
drawings, bar code or
2D code are disordered
(lines are not straight, but
wavy).
The workpiece is shaking during the
marking.
Perform vibration prevention measures.
The marking settings are not appropriate
for the drawing pattern of the filling lines.
• Change the scan speed.
• Adjustment the wait value in laser settings of
the “Marking settings” screen.
Marking is disorder.
(Characters lose shape
or not formed.)
Head lacks fixation strength.
• Fix head with the specified torque.
• Improve strength of head mounting.
Constant vibration from surrounding
equipment (motor and press, etc.)
influences.
Perform vibration prevention measures.
There are irregular vibrations coming
from surrounding equipment (air
cylinder and forklift, etc.).
(Marking is disturbed at irregular
intervals.)
Start and/or stop timing of feeder does
not match with marking operation.
Disturbed at the beginning of marking:
Marking trigger signal is likely to be input before
workpiece is fully stopped. Marking may disturb
due to remaining vibration even if workpiece is in
full stop.Turn the marking trigger signal ON after
vibrations are completely damped.
Disturbed at the end of marking:
Workpiece is likely to start moving before
completion of marking.
Delay start timing of feeder or speed up scan
speed so that marking is finished before
workpiece starts moving.
There are noises coming from
surrounding equipment.
Protect laser marker against noises as follows:
• Securely ground the frame ground terminal of
laser marker or surrounding equipment.
• Isolate power and signal lines from each other
if they have been routed in parallel.
• Shield signal line.
• Isolate power supply for laser marker from
other equipment.
• Use noise cut transformer to absorb noises
from power supply.
Marking line runs over
the intended start or end
points.
The setting in lasing quality parameters
does not match the other settings.
Adjustment the lasing quality parameters such as
starting point, ending point or wait value in laser
settings of the “Marking settings” screen.
When the character size
is small, the marking
characters are not
readable.
The setting conditions or font are
inadequate for the character size.
• Use “Original 2” or “Original 5” font for the
small size characters.
• Adjust the laser power or scan speed.
