5. MAINTENANCE &

TROUBLESHOOTING

To get maximum performance from the laser marking system and avoid damage, it is very important to
perform preventive maintenance in all components.

A maintenance plan for all components should always be established, and the working level and
characteristics of the surfaces of the product to be marked must be considered.

It is very important that the electrical power of the system be shutdown before any maintenance procedure,
to prevent any hazardous exposure to laser emissions. After the Laser Marker is turned off, it is
recommended to wait a minimum of 30 seconds before turning it on again. This action allows the
capacitors to discharge to an acceptable level before power is applied again.

This chapter also describes some of the system event message and what to do if the Laser Marker
displays a warning or a print failure message. The Laser Marker displays these messages in the user
interfaces if any problem occurs. In case the Laser Marker displays an event that is not described in this
chapter, you should inform your supervisor or contact your local HITACHI distributor.

ATTENTION

Before replacing any component, the end user should read Chapters 0 and 1 of this Manual.
