Abstract
Embodiments of the present disclosure provide a method comprising loading a medium onto an input tray of a imaging device; staging the medium within the imaging device, wherein staging the medium includes moving the medium from the input tray to a staging area within the imaging device; during the staging of the medium, determining an average load current of a motor that is associated with an automatic document feeder of the imaging device; and based on the average load current, determining a threshold load current of the motor, wherein the threshold load current corresponds to the panel of the imaging device having been opened.
