First, scan at higher resolution than yu plan to use. At least double.

SOmetimes i find that select by colour works well.
(1) make sure you have both blacks andwhites in your image, e.g. with
levels or curves.
(2) select by colour on a white area.
(3) grow selection e.g. 2 pixels
)4_ shrink selectin by 2 pixels
(6) feather by 1 pixel (requires greyscale or RGB iamge, not indexed)
(7) fill with white (e.g. drag the swatch from the toolbox, or use
control-. or control-,)
(8) select none

repeat steps 2 to 8 with black instead of white.
