Abstract: A scanner has a movable carriage, a contact image sensor located on the carriage, and a platen that is substantially transparent to visible light overlying the carriage and the contact image sensor. The scanner is selectively configurable between a first scanning mode for scanning substantially opaque media positioned on the platen and a second scanning mode for scanning media substantially transparent to visible light underlying the platen. At least one image on the substantially opaque media is located within a depth of field of the contact image sensor when the substantially opaque media is positioned on the platen. At least one image on the media substantially transparent to visible light is located within the depth of field of the contact image sensor when the media substantially transparent to visible light underlies the platen.

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.

Abstract: 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.
