260 Marking qualityTroubles Causes MeasuresMarking fades entirely/partially.Laser emission port is not clean.Refer to the “Safety / Setup / Maintenance Guide”“Maintenance” and clean contaminants off thelaser emission port.If contaminants persist, replace lens and/or laseremission port protection cover (glass). Contactour sales office.Fumes occurring during marking hinderlaser beam.Install dust collector.Check that dust collector works well.Distance to object is not appropriate. Adjust distance between bottom surface of lasermaker and target surface of object.For LP-M series:The displacement sensor input doesnot match the distance to the actualmarking surface.Confirm the displacement sensor and lasermarker input specifications and adjust thedisplacement sensor output (analog current value)to a suitable value.Input the displacement sensor trigger when thedisplacement sensor measurement value issteady.Match the displacement sensor measurementposition to the marking position.Target surface of object is inclined.Make adjustment so that bottom surface of lasermarker head and target surface of object areparallel with each other.For LP-M / LP-Z series:Setting of Uniform Spot Mode is notappropriate.Set the Uniform Spot mode within the requiredrange. If the setting of Uniform Spot mode ischanged, adjust the laser power as the density ofmarking may change.There are variations in properties ofobjects.Object thickness• Distance to object• Object surface condition (includingroughness, gloss level, etc.)• Object material (including chemicalcomposition ratio)Adjust marking conditions according to variationsfound.Object feeder is not stable. Adjust object feeder so that position of objectsbecome stable.Performance of laser oscillatordeteriorates due to aging.• Increase laser power setting.• Decrease scan speed.If initial marking quality cannot be reached evenif laser power is set to the upper limit, laseroscillator must be replaced. Contact our salesoffice.The marking densityof the filling lines in thedrawings or characters isuneven.For LP-M / LP-Z series:The drawing speed of the filling lines istoo fast and the Z-axis control modulecannot follow up the height change.• Decrease the scan speed.• Change the marking order or the line fillingdirections.ME-LPMSZ-OP-7 |
