| Zusammenfassung: | An image forming apparatus includes a first detection unit configured to output a first detection signal upon detecting a recording medium; a second detection unit configured to output a second detection signal upon detecting the recording medium, which is conveyed from the first detection unit; a signal generation unit configured to generate a substitute signal for the first detection signal in a case where the first detection unit does not output the first detection signal; and a state determination unit configured to determine a state of the image forming apparatus based on the first and second detection signals. The state determination unit determines that the first detection unit is in a failure state upon receiving the second detection signal and the substitute signal, which is input instead of the first detection signal. |
