I'm also having trouble getting a clean scan of a
black text on white
type-written page. I'm doing it at 300dpi and the page comes out looking
like shit on the computer. There are all sorts of spots and blotches
everywhere that are clearly not on the original, and the glass of the
scanner is crystal clear. I don't see an easy way of cleaning the page up
with the software I'm using (PaintShop Pro 3.0, I just downloaded 4.12 but
am still getting used to it).
I'm using PSP 5.0, and the built-in filters help a bit, but it seems like
there should be a better "get rid of background noise" filter. The
despeckle filter will help somewhat with scans of dithered material, but
to get a white background for greyscale scans, I ended up doing a flood
fill with the "tolerance" set to a suitably high value (like 60).
