Abstract
A replaceable unit includes a rotatable gear positioned on a housing of the replaceable unit and an encoded member encoded with identifying information of the replaceable unit. The encoded member is positioned on an axially outboard face of the gear such that the encoded member is rotatable with the gear for communicating the identifying information of the replaceable unit to a sensor of an image forming device when the replaceable unit is installed in the image forming device. The encoded member is configured to move axially outward relative to a rotational axis of the gear upon rotation of the gear in a first rotational direction for communicating the identifying information of the replaceable unit to the sensor. The encoded member is configured to move axially inward relative to the rotational axis of the gear upon rotation of the gear in a second rotational direction opposite the first rotational direction.
