Abstract: Disclosed is a fastener that comprises a stud member and a nut member. The stud member includes a base portion, a stem, a plurality of locating features, and, a plurality of slanted ridges. The stem has a head portion and a body portion, where the body portion is positioned on the base portion for enabling the stem to extend vertically from the base portion. The plurality of locating features extends from the body portion, and is disposed on the base portion. The plurality of slanted ridges extends from the stem. The nut member includes a central element configured to have two projecting members extending opposite to each other from a periphery of the central element. The central element comprises an aperture therewithin for receiving the stem therethrough and for interlocking the nut member with the stud member to retain the stud member at a locked configuration.

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.
