ABSTRACT:
A method for measuring dimensions of a stack of medium in a media input location of an imaging system, includes emitting light along a direction that is at a predetermined angle with respect to the normal of the planar surface of the media input location. An array of photosensors are disposed along an array direction that lies in a plane defined by the direction of the light and the normal of the planar surface. The photosensors receive a spatially-varying pattern of light reflected from a surface that is substantially parallel to the planar surface of the media input location to provide corresponding electronic signal data from the photosensor array for subsequent transmission to a printing system controller. The varying electronic signal data is used to provide a measurement of the one or more dimensions corresponding to the stack of medium.
