Luego, una luz potente se proyecta sobre el documento que deseas copiar, y la luz reflejada golpea el tambor.<\/p>\n<p>La luz reflejada desde las partes de &#8220;papel blanco&#8221; del documento descarga la electricidad est\u00e1tica en el tambor (esto utiliza una propiedad especial donde la carga se libera al incidir la luz).<\/p>\n<p>En consecuencia, solo las partes de &#8220;texto e im\u00e1genes negras&#8221; del documento (de las que no se refleja luz) permanecen cargadas en el tambor. \u00a1Esto crea exactamente la misma condici\u00f3n que las &#8220;letras invisibles&#8221; que dibujaste en nuestro experimento!<\/p>\n<p>Luego, se introduce un polvo de tinta fino llamado T\u00f3ner (\u00a1que cumple el mismo prop\u00f3sito que nuestro polvo de lana de acero!). El t\u00f3ner es atra\u00eddo y se pega solo a las \u00e1reas donde permanece la electricidad est\u00e1tica (es decir, las \u00e1reas del texto negro).<\/p>\n<p>Finalmente, esa imagen de t\u00f3ner se transfiere a una hoja de papel, y se aplica calor para fundirla (fijarla) firmemente, \u00a1y con eso se completa el proceso de copia! Es incre\u00edble pensar que una ciencia tan fascinante est\u00e1 oculta dentro de una m\u00e1quina cotidiana como una copiadora.
