Paper path powered jam/lock systems and methods

An image output device includes a marking engine and a media path adjacent the marking engine. The media path has a media transportation direction and a media transport element (e.g., a nip drive, a belt drive, a suction drive, an air pressure drive, etc.) within the media path that moves the media along the media path in the media transportation direction. A drive motor is operatively connected to the media transport element. The drive motor provides drive force in a forward direction that causes the media transport element to move media along the media path in the media transportation direction. The drive motor can also provide the drive force in a reverse direction opposite the forward direction. A one-way drive transfer device (e.g., a one-way clutch, a one-way swing arm mechanism, etc.) is operatively connected to the drive motor. The one-way drive transfer device only transfers drive force from the drive motor when the drive motor operates in the reverse direction. The reverse direction drive of the motor, in conjunction with a one-way drive transfer device, can be used to perform the lock/unlock or the open/close of a jam clearance mechanism, baffle, or shield.
