| Zusammenfassung: | The image forming system includes an image forming apparatus, and an option device including a setting unit that includes a setting port where a value is set in a state of being connected to the image forming apparatus, and an input/output port. The setting unit transmits a response signal to the image forming apparatus according to a comparison result between a value of first data received from the image forming apparatus and the value of a signal set in the setting port. The image forming apparatus transmits recognition data on the option device to the option device according to the response signal. The setting unit sets a value of a signal at the input/output port based on the recognition data. |
