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.
