Troubleshooting guide
Operational 
When printing to the laser system, 
the computer gives an error 
message “Printer out of paper” or 
“Printer offline and not responding” 
•  Laser not powered on 
•  Laser System is running a file 
•  The print file is too large for memory 
installed in laser system 
•  The Laser System has errors in the stored 
print file 
•  Parallel port cable not connected or not 
connected properly 
•  Bad parallel port in computer system 
•   
•  Damaged port in CPU 
•  Turn on laser system 
•  Wait for the system to complete the file 
•  Reduce the physical size of the file or try to 
print the file in sections 
•  Add more memory to the CPU 
•  Clear the computer’s print spooler, power 
OFF then power ON the Laser System 
•  Connect cable or reseat connection at 
computer and/or laser system 
•  Try printing to another printer using the same 
port 
•
Replace laser system’s CPU 
Focus carriage looses X-axis 
position and slams into the left or 
right side of the rail during high 
speed raster engraving 
•  Mechanical interference 
•  Dirty laser system 
•  CPU overheating 
•  Focus carriage X-axis bearing tensioning arm 
too tight or binding 
If the pattern is excessive: 
•  X-belt too tight 
•  Worn or binding X-axis bearings 
•  Worn or binding X-axis idler pulley 
•  Worn or binding X-axis motor 
•  Firmware needs updating 
•  Check if focus carriage makes contact with 
material or other objects 
•  Clean all optics, rails, bearings and belts 
•  Clean CPU filters, correct ambient 
temperature to be within specifications 
•  Remove carriage from rail, check for freedom 
of movement of tensioning arm. Lubricate if 
necessary. Position of tensioning arm should 
be no greater than 10 o’clock. 
•  Check and/or adjust 
•  Check and/or replace 
•  Check and/or replace 
•  Check and/or replace 
•  Check with Service Department 
When homing, the arm slams 
repeatedly for a few seconds 
•  Bent Y-flag 
•  Dirty or faulty home sensor(s) 
•  Faulty flex cable 
•  Faulty lower flex cable board 
•  Check and/or straighten 
•  Try to clean sensor(s) with compressed air 
•  Replace upper flex board (home sensor) 
•  Replace flex cable 
•
Replace Lower flex cable board 
When focusing, the Z-axis table only 
moves in one direction 
•  Dirty or faulty Z-axis sensor  •  Try to clean sensor(s) with compressed air, 
otherwise replace sensor 
When running the laser system, the 
laser system will “freeze”, the clock 
will keep advancing, but the 
operator will have no control over 
the system. The only way to restore 
the system is to power the laser off 
and then back on. This is a 
symptom of file corruption. 
•  Incorrect BIOS setting in computer 
•  Bad printer cable 
•  Usage of device in between computer and 
laser system 
•  Some other parallel port driver interfering 
with the laser system printer driver 
•  Faulty printer port in computer 
•  Faulty internal ribbon cable 
•  Damaged port in CPU 
•  Refer to manual on proper setting 
•  Replace printer cable 
•  Connect the laser system directly from 
computer with the printer cable 
•  Remove all other parallel port drivers and try 
again 
•  Try printing from another computer 
•  Replace internal parallel cable 
•
Replace laser system’s CPU
