    摘要: A cleaning apparatus (70) for cleaning, e.g. a photoreceptor belt (10), including an ultrasonic transducer (110) located under the photoreceptor belt (10) which provides vibrational energy to the surface to separate toner particles (87), from the surface of the belt (10). The transducer is positioned such that it is located directly opposite the cleaning nip (88) formed by a brush (80) with the belt. The transducer (110) reduces the adhesion of the toner (87) to the photoreceptor surface, thereby allowing the brush (80) to operate at reduced interference and voltage. The reduced interference and voltage results in toner (87) being collected only at the very tips (81) of the brush fibers (86) thus, allowing more effective detoning of the brush.

    摘要: A cleaning apparatus (70) for removing particles (120) from a substrate surface (10) comprises a dual polarity, commutated roll (110) which attracts toner and debris particles (120) loosened into a particle cloud from the surface (10) by an acoustical horn (140). The particles are attracted to and adhere to the commutated roll, whether right or wrong sign (i.e. positive or negative), and are removed from the roll, as the roll rotates, by a scraper blade (150). The particles are collected in a waste container as the particles are removed from the roll surface by the scraper blade. The cleaning apparatus does not contact the surface, thus preventing wear thereof.

    摘要: An electrophotographic device having an imaging member with a charge retentive surface, driven along an endless path through a series of processing stations that create a latent image on the charge retentive surface, develop the image with toner, and bring a sheet of paper or other transfer member into intimate contact with the charge retentive surface at a transfer station for electrostatic transfer of toner from the charge retentive surface to the sheet. For the enhancement of toner release from a surface at any of the processing stations, a resonator suitable for generating vibratory energy is arranged in line contact with the back side of the non-rigid member, to uniformly apply vibratory energy thereto. The resonator (100) includes a vibrational energy producing device (150); a horn member for transmitting vibrational energy, divided into a plurality of horn elements, each horn element including a horn portion and a contacting portion (159) in substantially non-contacting relationship with a horn portion and a contacting portion (159) or any adjacent horn elements, each horn vibrating when driven by the vibratory energy producing means, in an axial mode toner releasing vibration, and a transverse mode causing non-uniform response among the horn elements; and an energy dissipating media (202) inserted into the inter element gaps (200) for substantially damping the transverse mode vibration, while substantially allowing the axial mode vibration.

    摘要: A resonator (100) for generating vibratory energy is arranged in line contact with a charge-retentive member (10) bearing an image on a surface thereof, in an electrophotographic device, to apply vibratory energy uniformly to the charge-retentive member. The resonator comprises a suction device ( 162), a suction hron ( 158), and an air-tight seal arrangement. When the vibratory energy is to be applied to the charge-retentive surface, suction is applied at the line of contact of the horn with the surface, to draw the surface into intimate engagement with the horn. The invention has application to a transfer station, for enhancing electrostatic transfer of toner from the charge-retentive surface to a copy sheet, and to a cleaning station, where mechanical vibration of the surface will improve the release of residual toner remaining after transfer.

    摘要: An electrophotographic device of the type including a flexible belt charge retentive member (10), driven along an endless path through a series of processing stations that create a latent image on the charge retentive surface, develop the image with toner, and bring a sheet of paper or other transfer member into intimate contact with the charge retentive surface at a transfer station (D) for electrostatic transfer of toner from the charge retentive surface to the sheet. For the enhancement of toner release from a surface at any of the processing stations, a resonator (152) suitable for generating vibratory energy is arranged in line contact with the back side of the charge retentive surface (10), to uniformly apply vibratory energy to the charge retentive member. The resonator comprises a horn (156), a continuous support member (154), and a continuous vibration producing member (150) that drives the horn at a resonant frequency to apply vibratory energy to the belt. The horn includes a platform or base portion (156), a horn portion (158) extending therefrom, and having a contacting tip (159). The horn is segmented, through the contacting tip to the platform portion, into a plurality of elements which each act more or less individually. In alternative embodiments, the vibration producing member that drives the horn, and/or the support member may also be segmented in a corresponding manner.

    摘要: A printing machine and apparatus are disclosed that include an ultrasonically assisted cleaning blade (91) to remove toner particles from an imaging surface. An ultrasonic transducer (102) is attached to the cleaning blade (91) to provide vibrational energy to the cleaning blade. The ultrasonic transducer (102) concentrates vibrational energy at the blade tip for enhanced cleaning. A further element of the present invention is the addition of bias to create a strong electrostatic repulsion between the toner particles and the blade tip causing the toner to explode away from the cleaning edge, and to therefore enhance cleaning.
