I think it is happening everywhere but is most obvious in the blue regions.

I had a number of discussions with HP technical staff regarding the
banding problems in the HP film scanners, which also manifested mainly
in dark areas on slides and we batted this around a fair bit.
Banding seems to have an odd tendency to vary in making its appearance
in devices using stepper
Re the "banding problem"
My first reaction was that the scan is being done "off" a native
resolution 4000 dpi, 2000 dpi, 1333.333 dpi, 1000dpi etc and that software

They also said that they believed that service has been able 'fix' the

This was mentioned to me in passing by the one of the second level guys as a

This is a possibility. As I mentioned, when I had the LS8000, it did not always band. Sometimes it would and sometimes it wouldn't. Nikon tech support did mention moving the scanner to a different locati

I no longer have my LS8000 as I've mentioned. However, Camera World did want my Nikon case # so they could return it. If anyone wants the case #, I'll supply it.

Sorry, and I don't mean to be glib...but perhaps having an 85 pound scanner
may be an asset ;-)

I don't know how heavy the ED 8000 is, but these days most electronics
have minimal heft to them and aren't very solid.
I have found that as a result, using a solid platform for devices like

vibration in the shelf or table they

Somewhat true, but power supplies can still be quite heavy. It is 19.8 lbs.
Not really light, but certainly not all that heavy.

Actually, Nikon LS2000 and LS30 and I suspect all the newer 35mm
models, at least, move the scanning "unit" (CCD, lens and lighting
source and any mirrors), and not the film.
Yes, they move the film into frame position, but then the fine movement
is done by moving the scanner "head".
This does
