An optical scanning technique employs an optical sensor array for collecting image pixel data from a flat medium during a scanning cycle. A motion apparatus provides relative motion between the sensor array and the medium such that a spiral locus is defined by the sensor array relative to the media during a scanning cycle. The spiral maximum diameter may be made equal to the diagonal dimension of a rectangular media, thus allowing pixel data to be collected very close to the edge of the media, and so reducing or eliminating the area of unscannable margins on both sides and the top and bottom of the media. The motion apparatus can include a turntable for rotating the flat medium about a center of coordinates, and a translatable carriage holding the sensor array. An ink jet printhead can be mounted on the motion apparatus, to provide a multi-function scanner/printer machine.
