Abstract

A system includes a drive gear and a sensor mounted in an image forming device and a replaceable unit removably installable in the image forming device. The replaceable unit includes a gear for receiving rotational force from the drive gear. The system includes an encoded member encoded with identifying information of the replaceable unit and operatively connected to the gear such that rotation of the gear causes movement of the encoded member for communicating the identifying information of the replaceable unit to the sensor. The encoded member is configured to move toward the sensor upon rotation of the gear of the replaceable unit in a first rotational direction for communicating the identifying information of the replaceable unit to the sensor. The encoded member is configured to move away from the sensor upon rotation of the gear of the replaceable unit in a second rotational direction opposite the first rotational direction.
