    Abstract: An imaging device has a drive gear assembly which operatively engages with a backup roll gear of a fuser assembly when the fuser assembly is inserted into the imaging device. Such engagement causes the drive gear assembly to rotate, and in turn rotates a drive motor coupled to the drive gear assembly. The drive motor includes Hall Effect sensors associated with a sensor arrangement that senses rotation of the motor. During rotation of the drive motor, sensor signals are transmitted to a controller of the imaging device, the controller counting rising and falling signal edges of the received sensor signals. Based on the number of rising and falling signal edges, a message is sent to a user of the imaging device whether or not the installation of the fuser assembly was successful.

    Abstract: A gear assembly for an imaging device includes a drive gear positioned to receive rotational force from the imaging device, and a driven gear positioned to mesh with and receive rotational force from the drive gear for rotating a photoconductive member. As the photoconductive member rotates, a rotational location on the drive gear that meshes with the driven gear when a latent image is formed on the photoconductive member is the same said rotational location on the drive gear that meshes with the driven gear when a toned image of the latent image is transferred from the photoconductive member to an image receiving medium.

    Abstract: An Oldham coupler assembly for transferring rotary power between two shafts in an imaging device. The Oldham coupler includes an input plate and an output plate made of plastic and a star plate made of metal mechanically coupled and positioned in between the input plate and the output plate. A plastic retraction spline assembly is slidably retained in the output plate and engages with a drive member in an imaging unit. The location of the retraction spline assembly on the output plate allows for an increased diameter leading to increased torsional stiffness. The input plate includes gear teeth integrally molded into the outer circumference thereof helped to decrease the overall width of the Oldham coupler. Pairs of wheels are fastened to inner faces of the input and output plates and used to moveably couple the star plate to the input and output plates.

    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.

    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.

    Abstract: An Oldham coupler assembly for transferring rotary power between two shafts in an imaging device. The Oldham coupler includes an input plate, an output plate, and a drive plate and two pairs of coupling wheels, and, in one embodiment, made of the same plastic material. The drive plate has a pair of open-ended slots along one axis and a close-ended center slot along a second axis orthogonal to the first axis. The drive plate is mechanically coupled and positioned in between the input plate and the output plate. A plastic retraction spline assembly is slidably retained in the output plate and engages with a drive member in an imaging unit. The input plate includes gear teeth integrally molded into the outer circumference thereof decreasing the overall width of the Oldham coupler. The two pairs of coupling wheels have the same diameter.
