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

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.
