Hi, im a smal lab and i went up to cad cam and digital dentistry a few months ago, i ordered a Roland DWX50, and as an advice from my reseller i took a blue light Shinning 3d scanner, wich broke down three days after i was using it, i felt terrible bad becouse i had a lot of work pending, and it had to be delivered the next day, so well i ask the reseller what whats the problem ...
You bought a used machine from a third party. That's was your mistake. You should buy directly from the manufacture or a brand new one, then you woud have warranty and they would repair or replace it. That's the way I see it, has nothing to do with Shining 3D.
