Slightly off topic, but has to do with Roland.
The fuji heat controller in my 745 died. I called Roland for some tech help. They told me that the Fuji controller was $2,000 dollars and that they don't have them in stock. They couldn't get them and that I'd need to find a used roland printer to pull the part off of it.
I called fuji and bought one pre-programmed for $210.00. I then took the old controller and rebuilt it for $7.00 in parts (backup).
My machine was $30,000+ and Roland didn't have the part for it, which made it a paper weight. I was worried for a few minutes.
My point is that when the LEDs start to burn out in the Roland UV, you'll probably be able to replace them for a couple dollars per LED and solder in new UV LED's. $5,000 part rebuilt for pennies on the dollar.
