The dry paper copier, or photocopier, uses the photoelectric effect as its basic working principle.
The process is to spray electric charge upon the smooth surface of a semiconductor and then flash an image to be copied onto this surface. The light causes the plate to discharge in that local area. When pigment powder is sprinkled over the plate it sticks to the charged spots and falls off the discharged spots. The plate is then placed in contact with a blank sheet of paper to which the powder is transferred. Then the paper is heated under pressure to stick the permanently pigment to the paper.
