Patent ID: 8744280

Claim:
A method for determining whether a panel of an imaging device has been opened, wherein the imaging device includes (i) an input tray onto which a medium is loaded, (ii) an automatic document feeder configured to stage the medium from the input tray to a staging area within the imaging device, (iii) a motor load sensing module and (iv) a threshold load current determination module, the method comprising: staging, by the automatic document feeder, the medium within the imaging device, wherein staging the medium includes moving the medium from the input tray to the staging area within the imaging device; during the staging of the medium, determining, by the motor load sensing module, an average load current of a motor that is associated with the automatic document feeder; and based on the average load current, determining, by the threshold load current determination module, a threshold load current of the motor, wherein the threshold load current corresponds to the panel of the imaging device having been opened.
