A method for managing recording sheet jams in an image-forming apparatus includes detecting a current jam in the image-forming apparatus, storing a number of image formation operations performed by the image-forming apparatus when the current jam is detected, and a first determining step for determining whether the current jam is a true jam or a false jam based on a number of image formation operations obtained for a previous jam and a number of image formation operations for the current jam.
