| 1. A method of preventing incorrect media size selection in an image formation device, comprising:
detecting, with at least one side guide, a width dimension of print media disposed in the image formation device by a position
of the at least one side guide of a media storage area;
in a media size sensing routine or circuit, converting the position of the at least one side guide to a value corresponding
to the width dimension of the print media;
in a media size comparing routine or circuit, comparing the converted value to a plurality of predetermined groups of media
having respective ranges of width dimensions and determining a predetermined group of media having a width dimension within
a predetermined range of the converted and value;
determining whether the image formation device performs a function based on the comparison of the converted value to the predetermined
group of media; determining a number of media in a predetermined group of media having a width dimension within a predetermined
range of the converted value; determining whether the at least one side guide has been located at a current position previously
when there are two or more media in the predetermined group of media; determining whether a metric measurement default is
in an ON or an OFF position; and selecting from the predetermined group of media a most frequently selected print media having
a metric measurement when the metric measurement is in the ON position.
