Abstract:
1. A method for printing an image, the method comprising the steps of: defining a media support surface; advancing a print medium onto the media support surface; creating a substantially uniform field of transmissive illumination of the print medium by emitting light from a first light source and a second light source that are disposed on a first side of the print medium, wherein the first light source and the second light source are separated from each other along a scan direction; moving a field of view of a sensor on a second side of the print medium through the substantially uniform field of transmissive illumination as the sensor moves along the scan direction; monitoring the position of the sensor as it moves along the scan direction; sensing the light on the second side of the print medium which is opposite the first side while the sensor moves along the scan direction as the light passes through the print medium to the sensor; providing memory for storing patterns representing particular media types; providing a processor for comparing signals from the sensor to patterns stored in the memory in order to identify media type; identifying the print medium type; selecting a print mode based on the identified print medium type; processing an image according to the selected print mode; and printing the image on the print medium.
