  • Patent number: 10120305
    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.

The second moveable planar electrode is partially moved toward the first moveable planar electrode as the solid lubricant is consumed. A residual solid lubricant quantity detecting unit is provide to detect a quantity of the residual solid lubricant at a first stage, in which the residual solid lubricant quantity is below a given level, by detecting electric conduction between the pair of first and second moveable planar electrodes when the pair of first and second moveable planar electrodes contacts each other. The first moveable planar electrode is enabled to further move together with the second moveable planar electrode when it is contacted and pressed by the second moveable planar electrode.
