Abstract: A control method for an image forming system capable of preventing reduction of the ability of the system even if a shift transportation function becomes an abnormal condition. An image forming apparatus forms an image on a sheet. A first sheet process apparatus has a first moving unit receiving the sheet on which the image is formed and moving the sheet in a width direction. In a determination step, it is determined whether a second sheet process apparatus having a second moving unit moving the sheet in the width direction is connected to an upstream side of the first sheet process apparatus. In a detection step, it is detected an abnormal condition of the first moving unit. In a sheet movement step, the second moving unit moves the sheet in the width direction if an abnormal condition is detected and the second sheet process apparatus is connected.

Abstract: An image forming apparatus which enables the user to easily remove a sheet bundle left in the apparatus after a bookbinding-mode job is stopped in the middle of execution thereof. In a bookbinding mode of the apparatus, in a sheet stacking section, a plurality of sheets having images formed thereon are stacked as a sheet bundle; in a gluing section, glue is applied to an end face of the sheet bundle; and in a bonding section, a cover sheet is bonded to the sheet bundle to wrap the sheet bundle in the cover sheet. When a bookbinding-mode job is canceled during execution thereof, in the gluing section, glue is applied to the sheet bundle stacked in the stacking section before the job is stopped, and a discharge section discharges the glue-applied sheet bundle which is neither wrapped nor trimmed.
