Maintenance Details of Parts

WARNING
Laser emission port (fθ lens)
An f θ lens is mounted at the laser emission port of the head section. The fθ lens condenses laser irradiated from the
oscillator at the position of the work distance. On the lens surface, AR (anti-reflection) coating is applied in order to maintain
appropriate transmittance.
For LP-V/LP-W series, the protection glass of the laser emission port is attached to the laser aperture. It protects the fθ
lens from dirt or damage. AR (anti-reflection) coating is applied to the glass surface.
⿎ Effect from deterioration
Lens (for LP-V/LP-W series, protection glass) surface may become contaminated or receive dust generated during marking.
Using laser marker with the lens contaminated 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 marking
and processing.
⿎ Replacement interval
• Deterioration in quality of marking or processing (density reduction, incomplete marking or processing) is observed.
• There is contamination or scratch that cannot be removed by cleaning.
⿎ Replacement method
• For LP-400 series: Replaced at our service department. Contact our sales office.
• For LP-V/LP-W series: Refer to "Cleaning / Replacement of Laser Emission Port" (P.276) for the replacement of the
protection glass of the laser emission port.

• Maintenance work must be conducted with the power to the laser marker
turned OFF, and the controller 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.
