I had a similar problem with my 8000. It looked like fogging.
It was a dirty internal mirror. It tuns out that the 8000 (I don't
know about the 9000)uses a mirror to look up through the image. The
mirror faces up and it gets covered with fine dust after a time.
There are instructions how to disassemble the unit and clean it.
Clean both the lens and the mirror while you've got it apart. It's not
too bad if you have that type of aptitude and a steady hand, a clear
mind and some patience.
I had often left the a film holder in it with the door open and often
left the unit on. Now I always remove the film holder and close the
door. I also dust the film holders as dust will fall off them onto
the mirror. Finally, I taped over all the vent holes on the unit.
You SHOULD NOT DO THIS if you plan on extended use of the unit as it
will overheat, but for us amateurs who do small bits of scanning at a
sitting I don't imagine much heat buildup will occur. I can easily
remove the clear packing tape if I need to.
The 35mm slide that I first noticed it was:

Before I cleaned the 8000 I scanned the same slide on my Epson 4870 to
make sure there wasn't something I was missing.
On the Epson it looked like this:

After cleaning the 8000 the slide looks like this (although the image
isn't done to match the first very well.

Good luck!
