You can change this in umax.c, search for "y_dpi_range"
and comment out line

dev->y_dpi_range.max = SANE_FIX(dev->us.inquiry_optical_res);

and if you like some lines abouve comment out

dev->x_dpi_range.max = SANE_FIX(dev->us.inquiry_optical_res);

But there is a reason that I don't allow the higher resolutions:

If you use more than 600 dpi in X-Resolution, the scanner sometimes
gives back one pixel more or less than expected!

Bye
Oliver
