Epson has new scanning software on their support site for the following
scanners Perfection 1670, 2400 3170, 3200 and 4870.

There is also new software for the Expression scanners 800, 1600,
1640XL, 1680 and 1000XL.
 
I notice that I can set the DPI resolution to 12800, which is much higher
than what my 3200 is capable of. Does anyone know if they are multi
sampling?

It is utilizing interpolation.

They advertised the Epson 3200 as 3200X6400 is the 6400 interpolated then?

No, but it can only "capture" that many pixels per inch in one direction, so
3200 is as high as you can go before it uses the software to rez up. 6400
is just marketing fluff.

In terms of being able to resolve image information in that axis, the
6400 may be hyperbole since the optics simply are not up to the job.
However there are certainly 6400 real and uninterpolated samples in that
direction and consequently it is a bit more than "just marketing fluff".

When the sensor cannot actually resolve that sampling density, the
effect of additional samples is to reduce the noise of the resulting
scan - in much the same way as multiscanning does (albeit without
coincident samples or any computation, resulting in an oversized file
and inefficient storage).

Since AS specifically asked about multisampling in a previous post in
this thread, that benefit is a significant one over the pat answer that
you provided.

The first number (3200) is the optical resolution in the horizontal
dimension (the width of the paper or scanner bed).

The second number (6400) is the number of steps per inch the stepping motor
can move the carriage down the length of the scan.

The second value is determined by the quality of the scan. High speed or
quality and the scan resolution that is set.

If you do not set the scan at more than 3200 dpi, there is no interpolation.

I downloaded Epson Scan 2.6v and tried it with my Perfection 2400 but I
found some problems:
- in Professional mode the slides are not recognized, i.e. are treated as
documents, while in Beginner and Automatic mode it works
- when I close Epson Scan and want work with Epson Smart Panel I can't
because it says the scanner is assignated to another application
- the scale of accuracy with jpeg varies fron 0 to 100, with 0 the best and
default 16 - what is the relation with the usual scale with Epson Smart
Panel (0 to 100% with 100 for the best, default 80)?
- in general I don't know what is the difference of performance between
Epson Scan and Epson Smart Panel
TIA

I installed it on a friends Mac running OSX 10.3.8 with an Epson 4870. I
used to to scan 6 4x5 Velvia in professional mode, no problems.
