I did check over the optics with me little camera brush. The inside of the main plate was indeed hazy when I got it. This was a "Refurbished" and didn't get like that here...I keep printers, scanners etc., covered most of the time.
So much for their idea of refurbishment.
Transportation lock still lying in the parts hopper. No associated switchery.
USB lead. Well, they do say use only the supplied lead. I have to confess that I'd forgotten which came with it. They (3) are all from Epson and I've swapped them around. But it has me thinking. However, the Epson soft shows "Warming Up.".
I have a bad feeling that it will fall under your cat C.
What would be horrible is if the 'retina' has to be perfectly aligned. They would do it on some sort of set-up machine, while I try and test till summit happens. If I had to put the cover on each time to get the lights temp up...Ug! That would be as bad as the hours I spent putting the head-tabs back on the drum of an early video recorder. Well, they cost a month's wages then.
Financially, I would be well served to jump up and down on it. That would ensure no more time wasted. Mmmm...with me, I'm not so sure even that would stop me having 'Just another try before I dump it.'
