<p>An image forming system is installed along a transfer path for transferring a sheet and includes a sheet detection sensor for detecting the jam of the sheet. The image forming system includes a print device, a large stacker, and a paste bonding device, and metallic bonding device. Each of them has a cover. The cover can be controlled in a device by a user when it is opened. An open/close detection sensor corresponds to the cover and detects the open/close state of a corresponding cover. The image forming system displays a device which includes a sheet detection sensor for detecting jam when the jam is detected. The image forming system displays a moving picture which shows the release order of the jam when the open/close detection sensor corresponding to the cover of the device detects the open state of the cover.</p> |
