Abstract
A scanner has a movable carriage, a platen that is substantially transparent to visible light overlying the carriage, and a light source physically connected to the carriage for moving therewith. The light source is selectively movable between a first position for scanning substantially opaque media positioned on the platen, and overlying the light source, and a second position for scanning media substantially transparent to visible light underlying the light source.
