摘要： An arm that directs media sheets along multiple paper paths of an image forming device. The arm is mounted to pivot when contacted by the media sheet to direct the sheets along the proper media paths, and divert the sheets from entering the improper media paths. A sensor positioned adjacent to the arm senses movement of the arm to determine the location and timing of the media sheets as they move along the paper paths. Sensor is operatively connected to a controller which tracks the movement of the media sheets through the image forming apparatus. The arm may further be positioned to determine the orientation of an internal part. The arm moves between first and second orientations depending upon the position of the internal part. The position of the arm is again determined by the sensor. The invention further includes methods of moving the position of the arm to determine the location of the media sheets and/or the orientation of the internal part.

摘要： The present invention is directed to a device having an arm and a sensor that can differentiate two events. The arm is pivotally mounted to move in different directions upon the occurrence of different events. A section of the arm includes a trigger section having an unequal distribution of a sensed characteristic. A first event moves the arm in a first direction that is sensed by the sensor in a first manner. A second event moves the arm in a second direction that is sensed by the sensor in a second manner. The sensor signals a controller that oversees the image forming process. Methods of operating the arm and sensor are disclosed for detecting the two separate events, and signaling the controller accordingly.

摘要： The present disclosure relates to a method, system and apparatus for calibrating toner measurement in an image forming device. A toner patch is deposited onto a control surface, the toner patch reflecting light in a plurality of wavelengths in the infrared spectrum. A toner patch sensor emits light at the plurality of wavelengths in the infrared spectrum onto the toner patch. The amount of incident light reflected from the toner patch at the plurality of wavelengths from the emitted light is measured, and used to generate measured signals indicative of the reflectivity of the toner patch.
