WARNING

4-2-1 Protection glass of laser emission port

A protection glass is attached to the laser emission port (lens). It protects the lens from dirt or damage. An antireflection
coating is applied to the protection glass surface in order to maintain appropriate transmittance.
Do not remove the protection glass during operation.
„ Effect from deterioration
The surface of the laser emission port may become contaminated by the dust and smoke during the laser marking or
processing. Using laser marker with the contaminated laser emission port may cause the lens to get burned in. This may
also scratch the lens surface, or even peel off the surface coating depending on how it is used or cleaned.
Operations under these conditions will degrade transmittance of laser, which may lead to deterioration in quality of laser
marking or processing.
„ Replacement interval
• Deterioration in quality of laser marking or processing (density reduction, incomplete marking or processing) is observed.
• There is contamination or scratch that cannot be removed by cleaning.
„ Replacement method
• Replace the protection glass of the laser emission port referring to "4-2-2 Replacement of the protection glass" (P.132).
If the inside lens of the protection glass is damaged, our service representative handles the replacement. Contact our
sales office.

• Maintenance work must be conducted with the power to the laser marker
turned OFF, and the AC power cable disconnected. Doing so may cause
exposure to the laser beam or electrical shock.
• Do not insert your hands or objects to the exhaust port of each unit or the
gaps between units during the maintenance work. This may result in injuries,
electrical shock, or failure of the laser marker.
