摘要:
An image development system for developing a latent image on an imaging surface, such as a xerographic photoreceptor, with plural development rollers having internal axially extending developer magnets with relatively offset axial end positions, and wherein at least one development roller has a smooth surface area at that same end, to reduce edge banding image defects from the interaction of the axial ends of the magnets of adjacent development rollers, especially for large size copy sheets being printed, such as B4 size. The image developer unit may have three development rollers with three different lengths of developer magnets to provide three different magnetic end positions staggered on opposite sides of the end position of the large sheet (relative to the imaging surface).

An inkjet printer is configured to reduce the settling of magnetic particles in magnetic ink. The inkjet printer is configured to eject magnetic ink and black ink in areas where the corresponding image data only has black ink pixels. The printing of the magnetic ink in the black ink areas helps prevent the magnetic particles in the magnetic ink from settling.

This is a thumper assembly that is positioned in a developer station of a xerographic marking system. A waste container connected to a drop tube collects waste developer from this station. A magnet prevents magnetic developer from moving through the tube when the container is removed. Once a new container is installed, the magnet is moved away from the tube thereby allowing magnetic developer lodged therein to again move through the tube. A thumper is moved striking the tube to further dislodge developer and allow this developer to move through the tube into the waste container.

摘要:
A carpet stretcher foot comprising a base plate and a carpet stretcher receptacle pivotally connected to the base plate. The base plate has a plurality of nail holes adjacent its periphery. The carpet stretcher receptacle is rotatable about the base plate a full 360.degree. whereby the base plate may be secured to a floor with a carpet therebetween and the receptacle may be rotated relative to the floor and the base plate a full 360.degree. in stretching the carpet. There is also provided a method for stretching carpet comprising removably securing a carpet stretcher foot to a floor with a carpet to be stretched therebetween, the foot having a base plate and a carpet stretcher receptacle pivotally secured to the base plate, the receptacle being rotatable about the base plate a full 360.degree., the carpet stretcher having a stretcher head and an expandable tube positioned within the receptacle at one end thereof, the stretcher head being secured to the other end of the tube, the tube has opposite ends, stretching the carpet radially away from the foot with the carpet stretcher extending radially from the foot in spaced apart positions extending the length of the expandable tube, repeating the stretching step at radially spaced apart positions, repeating the expanding and the stretching steps until the carpet has been stretched from the foot to the positions adjacent the periphery to the floor, and removing the foot from the floor.
摘要:
An apparatus for developing in a development zone a latent image recorded on a surface, including a housing defining a chamber storing at least a supply of toner therein; a donor member disposed at least partially in the chamber of the housing and spaced from the surface, the donor member being adapted to rotate about a longitudinal axis to transport toner to the development zone in a region opposed from the surface; and a wire assembly module mounted in the development zone and extending in a direction transverse to the longitudinal axis, the wire assembly module including a wire and a drive/cleaning system for translating and cleaning portions of the wire in the development zone, and a power supply for electrically biasing the wire to form a toner powder cloud in the development zone for developing the latent image.
