Patent abstract
A full-loading sensing device and method thereof is provided for an image forming apparatus. The full-loading sensing device includes at least one lever rotated in different directions from reference locations by loading of a discharged paper and opening of a jam removal cover, respectively, and an optical sensor for sensing different rates of change in an amount of light corresponding to respective rotational directions of the lever. It is thereby possible to provide a single sensing mechanism that is capable of sensing and distinguishing both a full-loading state and a jam removal cover-open state.
