I first started this thread last year (http://groups.google.com/group/
comp.periphs.scanners/browse_thread/thread/35335d1555f9fd8c/
5edf75dba9525b67?hl=en#5edf75dba9525b67) but then got very busy at
work and ran out of time.

I've looked at the results with Vuescan 8.3.75 today and dust removal
(colour negs) sill doesn't work (IR3, heavy removal).

Looking more closely it seems the IR channel appears to be displaced
from the RGB image. Is this possible? Could I have a bad unit? The
scanner appeared to do two physical passes: is this expected?)

The Nikon scanners should not have any registration problems. Because
they use LED illumination, unlike other forms of illumination (lamps),
all "passes" for the final scan are done at once. As the mechanism
stops at each "scan line", the unit "flashes" the separate LEDs for red,
blue, green and IR in sequence, then the carriage moves to the next
"scan line".

There are (or may be, depending on settings) multiple passes, but they
are for auto-focus, auto-exposure and then the actual scan. However, as
far as I understand the actual scan itself is done in a single pass.

The FS4000 needs two passes. The first has the normal light enabled for
RGB collection. The second has the IR LED enabled for the dust scan.

I think the scans will often be misaligned and the software (Vuescan in
this case) has to resolve this. Have you tried an older version of
Vuescan to see if it solves your problem ?

Have you tried the latest version of VueScan 8.4.56? I think somewhere
along the way Ed fixed or at least improved the FS4000 cleaning
function problem.

As I've happily not been scanning I haven't tried it. Last time I
checked 8.4.37? it worked better than it ever has for single images
but managed to simply not save with IR correction for batch scans of
color negatives. The second pass was done and if you hit the save
button you could get a file with IR cleaning applied (sometimes) but
it didn't work automatically.
I don't know if this was fixed.

Please help Ed troubleshoot, other FS4000US users.

He did fix a huge focus problem around 8.4.3? that didn't exist at the
time of 8.3.75. "Progress"
