Problems solved by technology
[0021] However, if no cable is provided for communication between the sheet discharge processing device control section and the image forming device control section, if the sheet discharge processing device is temporarily disconnected or disassembled for maintenance such as sheet jam processing, then Communication has been disabled during this time
In this case, it cannot be determined whether the communication-disabled state is due to failure or maintenance unless the sheet discharge processing device connection detection section for detecting the mechanical connection between the sheet discharge processing device and the image forming device detects Disconnection or disassembly to the sheet discharge processing device

An image forming apparatus which is capable of judging whether or not a sheet handling apparatus is connected or faulty without provision of a sheet handling apparatus mechanical connection-detecting section, and reducing the size and manufacturing costs of the apparatus. To an image forming apparatus, a sheet handling apparatus is disconnectably connected. A communicating portion communicates with the sheet handling apparatus. A control sections judges whether or not the image forming apparatus or the sheet handling apparatus is abnormal. The control section provides a display for confirmingdisconnection of the sheet handling apparatus, if it is judged that the image forming apparatus or the sheet handling apparatus is not abnormal, when the communication with the sheet handling apparatus by the communicating portion is impossible.
Description
technical field [0001] The present invention relates to an image forming apparatus, and a method of determining the status of a sheet processing apparatus disconnectably connected thereto. Background technique [0002] Fig. 8 is a schematic diagram of a conventional imaging system. [0003] In FIG. 8 , the image forming system is constituted by an image forming apparatus 100 and a sheet discharge processing apparatus (sheet processing apparatus) 110 disposed in a sheet discharge portion of the image forming apparatus 100 . [0004] The image forming apparatus 100 is composed of an image forming apparatus control section 101 that controls the entire image forming system, an operation display section 102 that displays the state of the entire image forming system and is used to give instructions, and a sheet conveyance that conveys a sheet toward a sheet discharge processing apparatus 110 Channel 103 is composed. [0005] The sheet discharge processing apparatus 110 aligns a ...
