    摘要: A method for classifying an image as one of color and neutral assigns respective values associated with a plurality of pixels in the image to a plurality of respective current pixels. Reduced image pixels are produced as a function of the current pixels. The image is classified as one of neutral and color as a function of the reduced image pixels.

    摘要: An apparatus and method for dispensing toner in an electrostatographic printer includes apparatus for agitating toner contained by a relatively large toner container (e.g., 10-25 liters in volume). The apparatus includes a substantially vertically-oriented shaft supporting a blade that operates, as the blade rotates, to drive the contained toner mass upwardly, thereby aerating the mass and preventing compaction during toner dispensing.

    摘要: An apparatus in which developer material comprising carrier granules and magnetic toner particles is transported closely adjacent to a latent image. The developer roller transporting the developer material is electrically biased. The electrical bias has a wave form that removes a substantially uniform distribution of magnetic toner particle sizes from the carrier granules and develops the latent image therewith.

    摘要: A method for classifying pixels into one of a neutral category and a non-neutral category inputs a group of pixels within an image into a memory device. A color of each of the pixels is represented by a respective color identifier. An average color identifier is determined as a function of the color identifiers of the pixels in the group. One of the pixels within the group are classified into one of the neutral category and the non-neutral category as a function of the average color identifier.

    摘要: In a scavengeless development apparatus, an electrode wire is disposed between a donor roll and a latent image to form a powder cloud of toner to develop the latent image. A magnet is disposed along the electrode wire, and low-frequency AC is passed through the electrode wire. The electromagnetic forces acting on the wire from the interaction of the AC with the magnetic field are adapted substantially to cancel mechanical vibration of the electrode wire.

    摘要: An apparatus in which an electrostatic latent image recorded on a photoconductive member is developed with toner. A donor roll, spaced from the photoconductive member, transports toner to a development zone adjacent the photoconductive member, an electrode member is positioned in the development zone between the photoconductive member and the donor roll. The electrode member is electrically biased to detach toner from the donor roll so as to form a toner powder cloud in the space between the electrode member and the photoconductive member. In this way, the toner from the donor powder cloud develops the latent image recorded on the photoconductive member. A DC current is transmitted through the electrode member. A magnetic member interacts with the DC current flowing through the electrode member to substantially dampen vibrations of the electrode member.
