The patterns result from minor inequalities in the sensitivity of the CCD
cells used for each scan line.  The Nikon 8000ED uses a three-line scanning
assembly that has a tendency to cause banding such as you saw, but if it
becomes too much of a problem in a scan, you can tell the scanner to use
just one line for the scan, and the banding disappears (but the scan takes
three times as long, which is why the single-line scan is not used as
often).

I've detected banding in my 8000ED scans in very dark areas next to very
bright areas, but it is very slight, and in most cases it is so hard to see
that I don't bother with a "superfine" rescan of the image.
