• How it works

o “A hand-held scanner has a light source inside to illuminate the image or text to be scanned.You put the image or text on a flat surface, preferably taping it down to keep it steady and flat. You then take the scanner, press it flat on the image and slowly move it across the surface. This will send the image capture to the computer.
