Re: filmscanners: NikonLS-3510AF

I wish I could help, Richard, but I'm afraid you might have 
inadvertently proven something about Nikon...

Nikon has had ongoing stepper motor problems with their LS-30/2000 
series, and perhaps their LS-20/1000 also.  We were just musing 
yesterday as to whether the problems would be fixed on the new LS 
40/4000 and 8000 scanners, but now that we know the problems existed way 
back with the LS-3510AF, it seems less likely Nikon has figured it out yet.

If it makes you feel any better, Nikon charges an arm and a leg to fix 
their current models once out of warranty, as well.  They are an equal 
opportunity repair fleecer.  Not only that, but their repairs are known 
for repeat failures, if you ever get your unit back at all.

Regarding your problem... it could be something is slipping (are there 
any belts of rubber rollers?), or a gear is striped somewhere (I don't 
know the internals of these units), or you could be experiencing logic 
circuit meltdown, discrete components that are going off value, or even 
bad solder joints.  If there are any internal plugs or socketed chips, 
make sure they are cleanly and well seated.
