    摘要: Described herein are techniques that facilitate the prediction of the end-of-life of a direct current (DC) motor of an apparatus. The described techniques include tracking end-of-life indicative motor-response values of a DC motor based on an applied-voltage value at its corresponding specified speed of the DC motor when the motor is engaged. in response to the determination that the tracked values exceed a range of acceptable operational values, a health-status notification regarding that DC motor is generated. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

    摘要: In an implementation, an example method of indexing a media feed shaft in a media feed device includes rotating a media feed shaft and transmitting the rotation to an output gear that is remote from the media feed shaft. The method also includes sensing a feature of the rotating output gear and indexing the media feed shaft to the feature.
