发明名称 Method and apparatus for detecting an unsafe operating condition in an automatic document feeder
摘要 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.

主权项 1. 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.
