The jam detection device includes: a board to which a first output signal, a second output signal, and a timing signal for defining detection timings thereof are input in response to passing of cut sheets; a first wiring through which the timing signal is input to the board; a second wiring through which a conveying synchronization signal of the conveying device is input to the board; a conveying error detection unit that is disposed on the board and detects conveying errors of the cut sheets by detecting conditions of the first output signal and the second output signal at the detection timings; and a connection status detection unit that is disposed on the board and detects a connection status of the first wiring by comparing the conveying synchronization signal with the timing signal. |
