1437-2 Maintenance Details of PartsWARNING• Maintenance work must be conducted with the power to the laser markerturned OFF, and the AC power cable disconnected. Doing so may causeexposure to the laser beam or electrical shock.• Do not insert your hands or objects to the exhaust port of each unit or thegaps between units during the maintenance work. This may result in injuries,electrical shock, or failure of the laser marker.7-2-1 Laser emission port (f θ lens)An f θ lens is mounted at the laser emission port of the head section. The f θ lens condenses laser irradiated from theoscillator at the position of the work distance. On the lens surface, AR (anti-reflection) coating is applied in order to maintainappropriate transmittance. Effect from deteriorationThe surface of the laser emission port may become contaminated by the dust and smoke during the laser marking. Usinglaser marker with the contaminated laser emission port may cause the lens to get burned in. This may also scratch the lenssurface, 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 markingand processing. Replacement interval• Deterioration in quality of marking and processing (density reduction of the marking, incomplete processing) is observed.• There is contamination or scratch that cannot be removed by cleaning. Replacement methodReplaced at our service department. Contact our sales office. Cleaning steps for laser emission port (Daily maintenance)In order to maintain stable marking quality, the laser emission port needs to be cleaned regularly according to the usageenvironment.1. Turn OFF the key switch of the controller, and disconnect the AC power cable.2. Clean the laser emission port with an air duster for optics, and wipeit lightly with a soft cloth. If a contamination is severe, use a softcloth immersed in ethanol to wipe it.ワㄐㄕㄊㄆ• Do not wipe the laser emission port strongly, or touch it with a sharp pointed object.Laser marker might become faulty.WARNING • Never use an inflammable air duster. The laser beam may ignite the gas,resulting in fire.Soft clothLaser emission portME-LPGS-SM-8
