Ø Routine Maintenance Procedures
5. Use a vacuum with a soft brush attachment or a dust mop with an electrostatic cleaning
cloth to remove dust and particles from the inside drum surface.
6. Close right side door.
Light Shield
The light shield consists of two structures; the imaging beam scans in a gap between them.
Cleaning the light shield is only required if a foreign particle or hair on the light shield is blocking
the laser, causing an image artifact. It is recommended the drum be free of paper dust and
particles before cleaning the light shield. This will minimize the chance of recontaminating the
light shield. To clean the light shield:

park the media guides at their home position and move the light shield to the customer
access side of the machine.
3. Open the right side door to access the light shield.
4. The spokes of the light shield are spaced far enough apart that you can put your head
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:
®
1. Remove media from the LightJet 500XL. When in place, the air intake filter blocks light
from entering the machine.
2. Remove the filter grill to access the filter.
3. If the filter is dirty but otherwise undamaged, clean it using a mild solution of water and dish
detergent.
4. Thoroughly dry the filter using a cloth and/or forced air dryer. Water must never contact the
ECU circuit boards.

Power Distribution Checklist
Maintenance of the AC power system involves checking the following parts:
§
§
§
§
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.
Clearing Media Jams
Load Jam
To clear a media jam that has occurred during media loading:
1. Using the control panel, select Set Up/Motor Control/All Motors Reverse. Attempt to
retract 10 inches of media.
2. If the media moves freely, use “All Motors Reverse” again for 135 inches to rewind the
loaded media onto the infeed roll. Inspect leading edge of media for damage. Cut away
damaged media if necessary.
3. If the media does not move freely, it must be removed manually from the drum. Cut the
media before the infeed pinch rollers by running a knife in the slot between the idler roller
and the first guide vane. Remove the infeed media roll.
