The spots are noise that may or may not be too small to appear in the
preview image.
I solve such problems by increasing the analog gain.
The problem only happens on my scanner in the darkest area where the signal
from the CCD is rather low.
What you are seeing is random noise.  Multiple pass processing might clear
up the problem.

Not on my scanner.

Not on my scanner.  This sounds like an alignment problem in your scanner.

The signal from the CCD is too small.
