This is certainly an understandable answer, if not a solution, since I'm
"locked in" to the 2700ppi format for awhile.
If I may be so naive to ask: What is a "pel size?" I get the idea that
"sympathetic vibration" is in play here.

You'll find it easier to (a)change the film, or (b)get a higher resolution
scanner. Grain aliasing seems to be a particular problem of ~2700ppi
scanners,
because of the proximity of pel size to grain size. I've never seen much of
it
at all from the Polaroid 4000. It will be interesting to see if the new
LS4000
also escapes the problem. It should, but maybe LED lightsource and possibly
sharper optics may cancel some of the advantage.
