Re: filmscanners: My replacement 8000 is banding like the first one :-(

Yes...

Given that Nikon were reported to be having development problems with the 
higher res stepper motor for the new generation of product including the 
8000, and given that jaggies is probably a result of some stepper motor 
resonance, and given that the reported banding seems to be related to 
nothing predictable but is changeable, then it could easily in fact be 
related to processing timing and thus step times, so it seems likely that 
the banding problem may also be related to stepper motor issues.

Also since the 8000 presumably has a heavier scanning head than the smaller 
scanners (more ccd etc), the mechanical constraints are more serious and it 
may therefore be the most sensitive to such things and which may not show 
up as problems on their 35mm scanners.
