Quality Problems
• Check focal length setting under F4 function key > Machine Setting > Set Focus Lens to see if it matches
the type of the lens installed.
• Check if the focal lens is installed correctly or if focal lens is not fixed properly.
• Check if it is caused by the debris or dust builds up in the bearing tracks of X rail.
• Check if it is caused from the damaged or dirty focal lens and mirror 4 in the lens carriage which cannot
deliver the laser beam effectively.
Non-operational Problems
• Laser does not fire
1. If the red alignment beam is not visible, the laser beam may be misaligned. Adjust the reflection
mirrors for exact focus.
2. If the red alignment beam is visible, please check the driver power. The laser power may be set to too
low for detection. Increase the percentage setting of the Laser Power from the software driver or the
control panel.
3. Check if the laser power connector is connected.
4. For safety purposes, the laser will not fire when the top lid or the front door is open unless the door
sensors are defeated by shorting them with magnets.
5. Check water level or temperature of water cooler if the equipped laser requires water cooling. The laser
tube will automatically shut down itself if the laser tube is over-heated.
NOTE
•
Unplug the machine before examining the mirrors, lens, motion system or any other part of the
laser system.
Other Problems
• "Graphic Was Clipped…" Message
The size or location of graphic image may be bigger or beyond the legal working area. Do not place
graphic object, especially vectors, right from (3,0) origin position, or 0 at either x or y rail of working
area on application software. Take Corel Draw for instance, even when the vector line’s width has
been set to the thinnest, it may still go beyond the border and causes the error. If the message
appears randomly but frequently even image object is smaller or within the legal border, check or
change DRAM module, a bad contact or faulty DRAM could cause such error.
• Auto Focus Pin is Not Functioning
The focus pin could be stocked by greasy residue that gradually forms a coating. Clean the probe
with alcohol or acetone. Check the cable of focus pin, there might be a bad contact or breakage.
