Engraving Quality
Problem
"Fuzzy" looking raster engraving or small
text appears like a "double image"
Fine detail is missing such as the serif's
of characters or thin lines of script fonts
when raster engraving
Vertical or diagonal background pattern
present when raster engraving large
areas and/or large amounts of material
Horizontal background pattern present
when raster engraving large areas and/or
large amounts of material
Engraving disappears, becomes "lighter",
or
appears
"choppy"
when
engraving at high speeds within ½ inch of
Y-axis ruler
BASIC MAINTENANCE
Troubleshooting Guide
Possible Cause
•
Dirty laser system
•
Graphic, graphic software, graphic
software
setup,
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
•
Speed too fast for the material
•
Laser cannot respond to low duty-
cycle, high speed engraving
•
Out of focus
•
System needs tuning
•
Laser spot size too big
•
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
• Dirty laser system
• Slight pattern is normal
If the pattern is excessive:
• Laser is too cold or hot
• Laser tube is faulty
•
Normal condition. The laser system
raster
needs to accelerate and decelerate

•
Slow down engraving speed
•
Re-focus
•
Run "Tuning" feature in printer driver
•
Replace belt and/or drive gear, and
run "Tuning" feature
•
Replace laser tube
•
Slow down engraving speed
•
Run enhancement feature in the
printer driver
•
Re-focus
•
Run "Tuning" feature in printer driver
•
Use shorter focal length lens
• 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
• 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
• Replace laser tube
•
Move graphic and/or material to the
right, outside of this area
•
Slowing the raster speed down
reduces the effect
