Hi Bob,

Well, sorry to disappoint you, but I don't know!  If it's interpolated, then
it isn't really "optical" resolution...  The spec sheet says "Color Matrix
CCD line sensor"...what ever that is...and it does also say "Optical
Resolution 2400 dpi", which, if what you say is true, their spec isn't
accurate IMO.  I'll see if I can find out what sensor it actually uses, and
see if I can get a spec on it.

But, for $400 it's a very amazing scanner...

Regards,

Austin
