Raster engraving appears sharp on
both ends of the engraving but fuzzy
in the middle
• Dirty laser system
• Something is loose
• System needs tuning
• Worn X-axis belt and/or drive gear
• Tickle setting too low
• Faulty laser tube
• Clean all optics, rails, bearings and belts
• Check X-axis bearings, drive gear, idler
pulley, belt, and optics
• Run “Tuning” feature in printer driver version
4.17 and higher
• Replace belt and/or drive gear, and run
“Tuning” feature
• Adjust setting higher and recheck
• Replace laser tube
Engraving does not appear as deep
as it normally does
• Graphic, graphic software, graphic software
setup, color palette, monitor display colors, or
driver settings have changed
• Out of focus
• Material or material density has changed
• Settings have changed
• Dirty laser system
• Laser tube cooling fan filters are dirty
• Chiller not maintaining temperature(water
cooled versions only)
• Ambient temperature not within specifications
• Laser beam out of alignment with the optics
• Air Assist cone misaligned (air assisted
versions only)
• Faulty laser tube
• Check to see what has changed. Use
“Software Setup Guide” to properly setup the
graphics software to work correctly with the
laser system. Check driver settings.
• Re-focus
• Check material
• Check power, speed, PPI, and DPI settings
• Clean all optics, rails, bearings and belts

• Faulty laser tube
• Re-focus
• Clean all optics, rails, bearings and belts
• Check focus point of material and different
places, adjust height by shimming material or

• Using the focus tool, focus directly on the
surface of the table in all four corners. Table
should be within +/- .020 inches from one
corner to the other. Adjust if necessary.
• Check and/or adjust laser beam alignment
