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.

Scanner with an adjustable light source for scanning opaque and transparent media

Visible and infrared radiation is generated from phosphors within a cold cathode lamp. At least partially transparent media is irradiated with the visible and infrared radiation from the cold cathode lamp. Infrared radiation that passes through the at least partially transparent media is sensed, and an artifact signal is generated from the sensed infrared radiation. The artifact signal corresponds to one or more unwanted artifacts on the at least partially transparent media.
