Re: Scanning...
you do mean to use light, reflected off an image, create an electronic signal, right?

the light travels across and then down(repeatedly) the image in a stream, and image on the paper is first changed into a stream of reflected or non reflected light. this stream of light is further changed into an an electron signal by passing the reflected light, in stream, to a light sensitive switch, that turns on or off, dependant on the level of light reflected off the images. these changes from one state to another state are (the on/off signals) are electronic image of the information contained originaly on the paper.

or was it something else you had in mind?
