Abstract
An inkjet printer includes a media support defining a surface; an inkjet printhead oriented to eject ink toward the defined surface; a carriage that is movable along a carriage scan direction; a light source directed at the defined surface and positioned on a first side of the defined plane to provide an illuminated portion of the plane extending substantially along the carriage scan direction; a light sensing device mounted on the movable platform on a second side of the defined plane that is opposite the first side, which sensing device functions to sense media type by sensing light emitted from the light source and transmitted across the defined plane and to light sensing device; memory for storing patterns representing particular media types; and a processor for comparing signals from the light sensor to patterns stored in the memory in order to identify media type.
