I have now read several histories of the LS-2000 and the LS-30 scanners which involve problems with halos/flare that developed over time. This probably happens with most film scanners over time, as they pick up dust, evaporated or vaporized lubricants, plasticizers from wiring, residue off circuit boards, etc, smoke from cigarette smokers, oils from cooking and heating if in a home, etc.
All my projectors develop residue on the condensors, heat absorbing glass, and lenses, and mirror and require cleaning, so I suppose this can be expected from a film scanner also. The difference is that slide projectors make it pretty easy to get to the parts needing cleaning. I suppose some scanners are more susceptible than others to this problem, but probably it would be a good idea for them to be designed to allow for easy access to the parts that need cleaning. In terms of your scanner, the postings I have been reading suggest access to the mirror and lens isn't all that difficult, and the main issue is to take care not to damage them or to leave smeared residue on them. I'd stay away from the actual CCD.
