I've noticed on some (but not all!) of my prints I'm getting some newtons rings. I have a glass carrier in my Durst M600, and I guess the glass isn't anti-newton glass. What can I do, short of changing the glass, to avoid this?

put the film under heavy books for a week or two then scan it without glass carrier.
When I had 8000/9000ed, I have noticed newton rings With the glass carriers so I stopped using it.

There is not much you can do. You can try cleaning the film with film cleaner to see if you have a thin coating of something on the film. But the best way is to use a glassless carrier.

I found out what was causing the rings last night when printing. Basically, I was cleaning the glass with an anti-static cloth and the cloth has some sort of liquid embedded in it. The residue left on the glass after cleaning causes rings when I press the glass against the negative. Cleaning the glass with some windex got rid of the residue and the rings.

Just this guy, you know?
What brand of cloth, if you know? (so that I can avoid it)
That sounds distinctly like something that should not be anywhere near optics.

I experienced this problem just a few days ago too. I use a V700 and betterscanning.com's ANR glass insert thingies. They work most of the time, but sometimes this happens: http://www.flickr.com/photos/godzilla128/4519219707/
Since this IS anti-newton glass, my only guess is that it's either sticking (like yours) or bending weirdly under the weight. My film damn near curls into half-circles tho, so I might go with the "heavy books" method too.

I can't remember the brand. I bought it from Henry's in Toronto. I'm not longer so sure that is the issue... I can plainly see the rings if I put the neg in the carrier and shine a strong light on the carrier. It is very irritating and sometimes ruins my prints.
