Patent ID: 8849165

Claim:
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 said housing and spaced from the surface, said donor member being configured 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, said wire assembly module including a wire and a drive system configured to translate portions of the wire in the development zone, and the wire module configured to electrically bias said wire to detach toner from said donor member so as to form a toner powder cloud in the development zone with detached toner from the toner cloud developing the latent image, said wire assembly module further includes a stringing system configured to arrange said wire into a plurality of wires with adjacent wires being spaced from and substantially parallel to one another, the drive system including a grooved roller configured to position the plurality of wires within a cleaning zone as the grooved roller rotates, the cleaning zone including a cleaning device fixed to the wire assembly module and the cleaning device configured to remove toner from the plurality of wires as the grooved roller rotates and transports the wires through the cleaning zone, wherein the grooved roller includes one or more continuous helix shaped grooves to transport the wire from a first longitudinal position of the grooved roller to a second longitudinal position of the grooved roller.
