Hi Terry

In my experience, the best scans of schematics have been 1 bit b/w, minimum
300 dpi, preferrably 600 dpi.  This makes for a compact file, and if you're
reproducing black line drawings on a white background, typical of most
schematics, you shouldn't need anything else.

OTOH, If you scan a pcb layout, and the layout shows multiple layers, or
component placment along with the traces, etc, then 8 bit gray scale works
good.
