Abstract

A replaceable unit for an electrophotographic image forming device according to one embodiment includes a pocket formed on a first side of a housing. A bottom end of the pocket is open for receiving an electrical connector during insertion of the replaceable unit into the image forming device. An electrical contact is positioned within the pocket and is electrically connected to processing circuitry on the housing. An outer guide is positioned on the first side of the housing and below the pocket. A portion of the outer guide inclines inward toward the first side of the housing as the outer guide extends upward. An inner guide is positioned within the pocket on a first inner surface of the pocket, which faces toward the first side of the housing. A portion of the inner guide inclines inward toward the first side of the housing as the inner guide extends upward.
