My scanner is getting noisier and noisier. I had to work hard on this to remove the worst of the banding, but some still remains.

Another from the Muir Woods. 2 or 3 stops underexposed, but there's still an alright image there!

I'm assuming you're using a flatbed here - banding is often caused by dust in the calibration area (usually at the top of the platen). Make sure you clean that part of the platen thoroughly, not just the image area.
I'm using a Microtek i900 with glassless holders. The calibration area is an empty rectangle in the holder--nothing but air--so there is nothing to clean as far as I can tell. My guess is after six years of use the actual sensor or mirror assembly has accumulated dust and debris. I've opened it up and blown as much dust out as I can, but I hesitate to actually touch any of the guts for fear of making it worse or messing up the alignment. Images with subtle gradations and open space are the most visibly affected, as above. Busy, detailed images seem to mask the worst of the flaws. If only I had a proper darkroom instead....or a better scanner!
