Appendix C – Troubleshooting Guide

Engraving Quality

Problem Possible Cause Possible Solution

“Fuzzy” looking raster engraving or

small text appears like a “double

image”

• Dirty laser system

• Graphic, graphic software, graphic software

setup, color palette, monitor display colors, or

driver settings have changed

• Speed to fast for the material

• Out of focus

• System needs tuning

• Worn X-axis belt and/or drive gear

• Laser Tube is faulty

• Clean all optics, rails, bearings and belts

• 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.

• Slow down engraving speed

• Re-focus

• Run “Tuning” feature in printer driver version

4.17 and higher

• Try engraving in the upper right corner of the

engraving area. If engraving improves,

replace belt and/or drive gear, and run

“Tuning” feature

•

Replace laser tube

Fine detail is missing such as the

serif’s of characters or thin lines of

script fonts when raster engraving

• Speed too fast for the material

• Out of focus

• System needs tuning

• Laser spot size too big

• Slow down engraving speed

• Re-focus

• Run “Tuning” feature in printer driver version

4.17 and higher

•

Use shorter focal length lens

Vertical or diagonal background

pattern present when raster

engraving large areas and/or large

amounts of material

• Dirty laser system

• Slight pattern is normal

If the pattern is excessive:

• Loose motion system components

• Worn or damaged X-axis bearings

• Worn or damaged X-axis rail

• Clean all optics, rails, bearings and belts

• Don’t remove so much material or try

engraving shallower or deeper. Try changing

PPI and or DPI

• Use a 50% black fill to “halftone” the

background which can hide the pattern

• Check X-axis bearings, belt, optics

• Replace X-axis bearings

•

Replace X-axis arm

Horizontal background pattern

present when raster engraving large

areas and/or large amounts of

material

• Dirty laser system

• Slight pattern is normal

If the pattern is excessive:

• Laser is too cold or hot

• Laser tube is faulty

• Clean all optics, rails, bearings and belts

• Don’t remove so much material or try

engraving shallower or deeper. Try changing

PPI and or DPI

• Use a 50% black fill to “halftone” the

background which can hide the pattern

• Check and/or clean filters

• Make sure ambient temperature is within

specifications

• Check AC electrical supply for power

instability

•

Replace laser tube
