Abstract

An illuminated media position indicator for an imaging device comprises a scanner having a scanner top cover including an inner edge portion which defines an opening for a scanning platen disposed adjacent the opening. The inner edge portion defines at least one corner corresponding to a scan origin. An illuminated registration corner is positioned in said at least one corner corresponding to the scan origin and comprises at least one LED in optical communication with the illuminated registration corner. The illuminated registration corner communicates light from the at least one LED throughout the illuminated registration corner using substantially total internal reflection to indicate media position and orientation at said scan origin.
