  • Publication number: 20060087070
    Abstract: A media stack height sensor in an image forming apparatus with a flag arm that is in contact with a top surface a media stack. The arm is coupled to a flag characterized by varying transmissivity. The flag is moveable by the flag arm so that as the position of the arm changes in relation to the stack height, a different portion of the flag is positioned between a transmitter and receiver of an optical sensor disposed within the body of the image forming apparatus. The flag accordingly reduces the amount of optical energy received by the receiver. The receiver output signal indicates the height of the media stack. The flag also includes features that further limit light transmission to the receiver to provide discrete stack height indications such as low, empty, full, or intermediate states.

  • Publication number: 20050211902
    Abstract: An optical density sensor disposed over a target surface in an image formation apparatus comprises an integrating cavity having a diffuse, reflective interior surface and a view port formed therein. An optical source directs light through the view port onto the target surface, without striking any interior surface of the cavity. Light reflected from the target surface is detected by an optical detector disposed within the cavity. The optical source may be disposed in a collimator, which may extend into the interior of the cavity, and may include a lens. A circuit card which may include an optical detector sensing circuit may be disposed proximate the optical detector. A compensating slot formed in the cavity may allow some reflected light to directly impact the optical detector as the gap between the cavity and the target surface increases.

  • Publication number: 20050201808
    Abstract: A media sensor for an image forming apparatus is operative to sense and distinguish opaque, transparent or no media in a media path. In one embodiment, an optical source and detector are positioned on opposite sides of the media path, at an acute, non-zero angle with respect to a direction normal to the media path. In other embodiments, an optical source and detector are co-located on the same side of the media path with an optical barrier between them, and one or more reflective surfaces positioned on the opposite side. With no media in the media path, the detector receives a readily detectable amount of optical energy emitted by the source. For opaque media, the detector receives very little, if any, optical energy emitted by the source. For transparent media, the detector receives a level of optical energy between that in the cases of opaque media and no media.
