Abstract
La presente invención se refiere a un aparato para cargar una superficie fotoconductora a un potencial sustancialmente uniforme, en una máquina de impresión que tienen una estación limpiadora, para la limpieza de la superficie, y una estación de exposición, para exponer la superficie a una fuente de luz que incluya un primer mecanismo para cargar la superficie a una potencial sustancialmente uniforme de una primera polaridad, después que la superficie es limpiada en la estación de limpieza. El aparato incluye además un segundo mecanismo para cargar la superficie a un potencial sustancialmente uniforme de una segunda polaridad opuesta a la primera polaridad, después que la superficie es cargada a un potencial sustancialmente uniforme de la primera polaridad, por el primer mecanismo de carga, y antes de que la estación de exposición. En forma similar, un método para cargar una superficie fotoconductora a un potencial sustancialmente uniforme en una máquina de impresión que tiene una estación de limpieza para limpiar la superficie, y una estación de exposición para exponer la superficie a una fuente de luz, incluye los pasos de (1) cargar la superficie a un potencial sustancialmente uniforme de una primera polaridad, después que la superficie es limpiada en la estación de limpieza; y (2) cargar la superficie a un potencial sustancialmente uniforme de una segunda polaridad opuesta, a la primera polaridad, después del primer paso de la carga de la polaridad, y después que la superficie se expone a una fuente de luz en la estación de exposición.
