Don't scan in black/white, you better scan in grayscale (white, and 254 
shades of gray, and black). This way you don't get jagged edges. 
Instead, they might now look somewhat smooth / fuzzy. But that you can 
change in an image editor by using gradient curves or levels (change 
white point and black point to bright gray / dark gray respectively) to 
make the edges sharper, and change the midpoint (middle gray) to fatten 
or thin the glyphs.
