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

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.
