This ends in around 1325dpi, optical, if not stitching strips, or course. Then the scanner firmware/driver makes a sharpening that delivers an improved look from the 1325 peformance, but this also limits the amount of sharpening you can later do with PS.
This is technical exact information, go and find a flaw in it.
