We have an LEF 20 -- precursor to the LEF 200, I think. On the frame of the UV hood at the upper right corner (Photo 1 red circle) it has a tab (2nd Photo red circle) that when closed projects into the safety switch (green circle on 2nd Photo) and allows the machine to run. For reasons, good and bad, I learned to defeat this with a little stick of 1/32 tactile (photo 3) -- this would let me run the printer with the hood up and, of course no one was allowed in the room, except maybe with 60 SPF suntan lotion. It might have been a technician that showed me this when he broke the tab off during a frustrating service call. Your machine looks similar. So if you have the tab and switch...
And always wear sunscreen.
