Clean air filter when it is dirty with dust etc. If the air filter is
dirty, the air-flow might become bad and might stop marking
operation. Exchange air filter periodically.
While marking is carried out, dust and/or
gas may be produced from the place to be
marked. Always ventilate and remove
them using a dust collector, etc.
Not collecting dust may affect the marking quality
badly.
When the laser marker is not used for a significant period of time,
be sure to save the back-up data of the laser marker files. During
the unelectrified period, the battery for the back up will be out of
charge and the data in the laser marker may be deleted.
