1. A method of detecting a type of media for use in an imaging apparatus, the method comprising the steps of:

  • reading a backside of the media to detect a presence of indicia on the backside of the media;

    measuring a frequency of repetition of the detected indicia along a lengthwise direction of the media;

    determining a spatial distance between the detected repeating indicia on the backside of the media; and

    comparing said spatial distance against stored predetermined spatial distances of indicia on reference media to determine the type of media.
