    摘要： Electrodes are embedded in a biased charge roller of a xerographic device. The electrodes, which may run the length of the roller, are deposited on an insulating substrate. A semi-conductive conformable layer of a flexible elastomer covers the electrodes. The semi-conductive conformable layer limits current flow between electrodes and relaxes charge deposited on the roller surface. Stationary pre-nip and post-nip contacts apply the bias to the imbedded electrodes. The electrodes in the post nip region are biased to VPOST. The electrodes positioned in the pre-nip regions are either grounded or biased to VPRE

    摘要： Electrodes are embedded in a biased transfer roller for the transfer of a xerographic image. The electrodes, which run the length of the roller, are deposited on an insulating core surrounding the shaft. A conformable semi-conductive layer of a flexible elastomer covers the embedded electrodes. The semi-conductive layer limits current flow between embedded electrodes, relaxes charge deposited on the roller surface, and maximizes the electric field that attracts the toner from the photoconductor to the image receiving surface (substrate or intermediate). The electroded biased transfer roller may tailor the electric fields within the nip, pre-nip, and post-nip regions between the photoreceptor and the image receiving surface of the xerographic device.

    摘要： An apparatus in which a liquid image is transferred from a surface to a substantially electrically non-conductive, flexible copy sheet with the liquid image being charged to one polarity and the surface being charged to a polarity opposite to the polarity of the charge of the liquid image. A first charge is applied on the copy sheet. The first charge is of the same polarity as the polarity of the charge of the liquid image. This causes the copy sheet to adhere releasably to the surface with the liquid image being interposed therebetween. A second charge is applied on the copy sheet after the first charge has been applied thereon. The second charge is of an opposite polarity to the polarity of the charge of the liquid image. This causes the liquid image to be attracted to the copy sheet.

    摘要： An apparatus in which a plurality of liquid images are transferred from a photoconductive member to a copy sheet. The liquid images, which include a liquid carrier having toner particles dispersed therein, are attracted from the photoconductive member to an intermediate web. A substantial amount of the liquid carrier is removed from the intermediate web and the toner particles are secured thereon. Thereafter, another liquid image having toner particles of a different color from the toner particles of the first liquid image, is attracted to the intermediate member. Once again, the liquid carrier material is removed from the web and the toner particles of the second liquid image are secured thereon. Thereafter, all of the toner particles are transferred from the intermediate member to the copy sheet, in image configuration.

    摘要： According to aspects of the embodiments, there is provided methods of optimizing contact forces between transfer and photoreceptor belts in image forming devices. The method acquires initial and operational set point data for the photoreceptor and transfer belt at different stages of engagement. Yaw motion is applied to reduce any misalignment between the belts based on the acquired data. A processor is used to determine misalignment between the photoreceptor belt and the transfer belt, and an actuator can be used to apply yaw motion. The yaw motion can return the transfer belt and the photoreceptor belt to their initial set position, or return a steering subsystem actuator to its setting prior to engagement of the belts. Set point data can be from the respective transfer steering subsystem for the photoreceptor and the transfer belts.

    摘要： An apparatus for enhancing toner release from an image bearing member in an electrostatographic printing machine, including a resonator suitable for generating vibratory energy arranged in line contact with the back side of the image bearing member for uniformly applying vibratory energy to the image bearing member. The resonator includes a piezoelectric transducer and a horn-type waveguide assembly, wherein an adhesive epoxy augmented with a substantial concentration of electrically conductive, free flowing particulate bead elements is used to bond the horn and piezoelectric transducer element together, without the requirement of a backing plate or bolts. The conductive beads resolve bond layer thickness anomalies while eliminating adhesive flow restrictions such that substantially uniform tip velocity and frequency output can be achieved.
