An apparatus comprising; a frame; a drum supported on said frame and having a partially cylindric internal support surface extending along and facing toward a central axis and having a given radius of curvature taken from the central axis; a scanning means supported by said frame and juxtaposed relative to said internal support surface so as to cause a light beam to sweep a path across the support surface; means for holding a media sheet on said support surface during a scanning operation in registration with at least one reference axis; a supply means defined by said frame for receiving a supply of media sheets and maintaining said supply of media sheets in a given orientation with respect to said at least one reference axis; and transport means extending between said drum and said supply means for lifting a media sheet from said supply means and for advancing it toward and placing it onto said support surface where a scanning operation is conducted and for removing said media sheet from the support surface after a scanning operation is completed on the involved media sheet; said supply means being so constructed as to maintain said sheets of media in a substantially flat condition and said transport means including sheet gripping means which travels with the transported media sheet from said supply means to said drum for lifting the transported media sheet from said supply in a substantially flat condition, for then bending said transported media sheet to a partially cylindric configuration conforming generally to said internal support surface of said drum, and for thereafter placing said transported media sheet onto said support surface while said transported media sheet is held in said partially cylindric configuration and is moved in a direction generally normal to and toward said support surface.
