When creating/editing profiles within NAPS2 the maximum value I can select for Resolution is 1200 dpi, yet my scanner specifications list 4800x9600 dpi as the Optical Resolution. Why is my maximum selectable resolution not consistent with the specifications? I realize that using resolutions higher than 1200 dpi may not give noticeably better results.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
What is the scanner model? I bet the scanner doesn't really do 9600dpi optical resolution.
Just to satisfy my curiosity: A quick Google search shows me that the highest optical resolution of any commercially-available scanner is the Epson Perfection v800 which tops-out at 6400dpi. And when movie studios scan 35mm film, they use 4800dpi.

It's a Canon CanoScan 4400F. The specs are listed in the Quick Start Guide Instructions document on this page:

Dang, the dude's right! eats own words I wonder if the 1200dpi hard-coded into the source somewhere
