Varian CARY 5000 not initializing upon startup

I just bought a used CARY 5000 with sphere. Everything seems to work , software etc. but it will not initialize with or w/o DRA accessory on. The left micrometer was jammed. I opened the cover, loosened the belt and unstuck the left one. It was at its limit and over tightened by servo. After i put the belt on it has not jammed.

Do you think it is out of alignment? in zero order, I can see the the light on both ports hitting white paper....What can i do to get this thing to pass the uv and NIR initialization????
