Someone mentioned something in the past about a mirror in the Nikon LS30/2000
as being extremely delicate and not something the user should touch.  But
I may be misremembering.

I presume the halos aren't on the film and you checked very carefully to
be sure.  To be honest I wouldn't have seen these halos if the scan had
been mine, and they wouldn't be a significant enough problem for me to get
upset about.  The posted images look to be unadjusted output from Vuescan
- by the time the levels, brightness and contrast were adjusted, I'd be
surprised if the halos were visible.

I've been quite happy with the LS30 once the jaggies problem was addressed
by using Vuescan.  From a brief comparison, the output it produces compares
surprisingly well with the SS4000 for colour and sharpness, but not shadow
detail.  That's to be expected.  But then the SS4000 cost twice as much
as the LS30 at the time.
