You can't sharpen the image using 24 bit color. It will only give you 
shades of gray and other faint colors.  You need to set your scanner for 
black and white, and turn up the contrast. You then need to increase the 
brightness until the background drops out.  This takes some 
experimentation to get a readable image. frequently this results in the 
scanner "seeing" the image on the back of the page. In this case, I put a 
sheet of black construction paper behind the page. This gives a uniform 
background.
