between them and look through the gap to find any debris. A small flashlight can be helpful.  
Use compressed air or tweezers to remove debris. Use caution when handling the light shield.  
It can be damaged if any appreciable weight is applied to it.  
5. Using a can of clean air, spray the problem area liberally. Direct the air so that it is blowing  
air outward through the gap in the radial direction.  
6. Close the right side door.  
Intake Air Filter  
The intake air filter is located at the base of the machine on the left-hand side. To clean or  
replace:  
®

§
§
§
§
Building circuit breaker for dedicated power  
Input power cord condition  
Input power cord connection at the wall outlet  
Input power cord connection on the power distribution unit (PDU).  
Checking the Cooling System  
The cooling system consists of two cooling fan assemblies and one air blower. One (dual) cooling  
fan assembly is located under the electronic control unit (ECU). The other (single) fan assembly  
®
is located on the rear panel left side of the LightJet 500XL.  
The greatest heat source is the blue laser head, which is cooled by the blue laser blower. It is  
imperative that the airflow through the vent hose never be restricted or the blue laser could be  
damaged and image quality degraded. If overheating does occur, the blue laser will shut down,  
®
interrupting image production. Refer to the LightJet 500XL Site Preparation Guide for heat  
removal specifications.
