摘要： An apparatus in which a developer unit of an electrophotographic printing machine has a plurality of wires which trap contaminants before reaching electrode wires positioned between a donor roller and a photoconductive surface. In addition, a circuit determines when defects and deletions are caused by contaminants spacing the electrode wires from the donor roller.

摘要： A carrier bead pickoff device for removal of carrier beads adhering to a charge retentive surface in an electrophotographic device having at least one developer housing movable into and out of developing position includes a magnet supported on the movable developer housing of the type which is movable into and out of developing position with respect to the photoreceptor. When the developer housing is moved into developing position, the magnet is correspondingly brought into a position closely adjacent to a non-magnetic carrier bead catch supported closely adjacent to the charge retentive surface. Beads are collected at the bead catch and released upon removal of the magnet from proximity to the bead catch. The non-magnetic bead catch may be supported for movement into a bead catching position when the developer housing is brought into developing position, and to a bead releasing position when the developer is removed from developing position and the magnet is removed from its position adjacent the bead catch. When the bead catch is in bead catching position, the magnet is supported so that removed beads are collected at the bead catch by the magnetic force. When the magnet is removed from that position, there is no longer a magnetic force attracting beads to the bead catch, and the movement of the bead catch to a bead release position allows collected beads to fall to a storage location.

摘要： An apparatus in which an image region recorded on a photoconductive surface is developed with a developer material comprising at least carrier granules and toner particles. The developer material has the resistivity thereof varying continuously as a function of the electrical field applied thereto. A transport moves the developer material closely adjacent to the photoconductive surface. An alternating electrical field is generated between the transport and the photoconductive surface. The alternating electrical field has an amplitude sufficient to change the resistivity of the developer material to a more conductive state.

摘要： A printing device can be configured with different numbers of ink colors and ink types to print with a different cross-process direction print resolution for each ink color and ink type. The printing device includes a plurality of printhead arrays with each printhead array being configured to eject ink onto an image receiving surface at a first print resolution in a cross-process direction. Each ink supply in a plurality of ink supplies is configured to provide ink to one printhead array in the plurality of printhead arrays, and a controller is configured to operate the printhead arrays at one of at least two combinations of ink colors and ink types. The controller operates the printhead arrays ejecting a same ink color or a same ink type at a second print resolution in the cross-process direction that is different than the first print resolution.
