Abstract: A roll assembly according to one example embodiment includes a rotatable input shaft. The input shaft is supported by a housing. At least one gear is mounted on the input shaft. A carrier frame is mounted on the input shaft and rotatable independent of the input shaft. A plurality of rolls is rotatably mounted about a periphery of the carrier frame. An axial direction of rotation of each roll is transverse to the rotational axis of the input shaft. Each roll has a contact surface and a gear face that is operatively coupled to the at least one gear. A first one-way clutching surface is positioned between one of (1) at least a portion of the rolls and the carrier frame, (2) the carrier frame and the input shaft, (3) the carrier frame and a portion of the housing, and (4) a combination thereof.

Abstract: A drive apparatus for driving media sheets in a printing device is disclosed. The drive apparatus includes a fuser drive train, a duplexer drive train, an exit roll gear and a bell crank. The bell crank is at least partially disposed in-between the fuser drive train and the duplexer drive train and is capable of swinging to assume one of a first position and a second position. The bell crank in the first position couples the fuser drive train to the exit roll gear driving the exit roll gear in the first direction for driving a media sheet into an output bin of the printing device. The bell crank in the second position couples the duplexer drive train with the exit roll gear driving the exit roll gear in the second direction for driving the media sheet along a redrive path into the printing device.

Abstract: A printing system for duplex printing of a banner media is disclosed. The printing system includes a drive roll, a pair of nipping rolls abuttingly coupled to the drive roll forming a first nip and a second nip with the drive roll, a media path including a printing region and a duplex region, and a diverter disposed in the media path and coupled to the drive roll. A first side of the banner media is printed in the printing region and exited partially from the first nip. Further, the partially exited banner media is re-fed into the duplex region and transferred to the printing region to print the second side of the banner media and exited from the second nip. The duplex region is capable of receiving the banner media from the first nip and the printing region is capable of exiting the banner media from the second nip simultaneously.
