Abstract: An apparatus for efficient cleaning of the imaging surface. The primary cleaner is a rotating collection roll located directly opposite from andon the other side of the imaging surface from the ul trasonic cleaning assist device. The ultrasonic energy is used to remove the toner from the imaging surface enabling attraction toward the biased collection roll. The ultrasoni c energy decreases the amount of residual toner remaining after transfer. The residual toner that is not cleaned from the surface by the collection roll i s removed from the surface by the rotating biased conductive brush, which is the secondary cleaner. The collection roll is contactless in that it does no t come into contact with the photoreceptor. In another embodiment of the invention, the primary cleaner and the secondary cleaner are collection roll s with ultrasonic cleaning assist devices directly under each collection roll. Theentire cleaning system is contactless. - 22 -

Abstract: Acoustic Transfer Assist (ATA) systems are used in media printing devices to help transfer toner to paper by use of ultrasonic vibrations. A transducer (10) is driven at its resonant frequency, though somewhat dampened. To shorten the decay time of the transducer when its vibration is not desired, a compensating signal is used. A reverse drive voltage is used during transducer shut-off. The reverse drive causes the transducer to vibrate at its normal resonant frequency, but at a 180° phase shift, causing the transducer to stop vibrating significantly faster than without a reverse drive. An open phase-locked loop system drives the transducer from resonance to rest. When the transducer stops vibrating, current to the reverse drive loop is cut off.

Abstract: An apparatus for efficient cleaning of the imaging surface. The primary cleaner is a rotating collection roll (210) located directly opposite from and on the other side of the imaging surface from the ultrasonic cleaning assist device (220). The ultrasonic energy is used to remove the toner from the imaging surface enabling attraction toward the biased collection roll. The ultrasonic energy decreases the amount of residual toner remaining after transfer. The residual toner that is not cleaned from the surface by the collection roll is removed from the surface by the rotating biased conductive brush (200), which is the secondary cleaner. The collection roll is contactless in that it does not come into contact with the photoreceptor. In another embodiment of the invention, the primary cleaner and the secondary cleaner are collection rolls with ultrasonic cleaning assist devices directly under each collection roll. The entire cleaning system is contactless.

Abstract: 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.

Abstract: Eine Vorrichtung zum Aufdrucken auf Medien und Verfahren zum Abstreifen von Druckmedien von Riemen sind hierin offenbart. Eine anschauliche Vorrichtung, die zum Bedrucken von Medien geeignet ist, umfasst ein erstes Element mit einer ersten Oberfläche, ein zweites Element, einen Fixierriemen, der auf dem zweiten Element aufliegt und eine innere Oberfläche und eine äußere Oberfläche aufweist, wobei die erste Oberfläche und die zweite Oberfläche einen Walzenspalt bilden, an dem die Medien empfangen werden. Die Vorrichtung umfasst ferner eine vibrierende Abstreifeinrichtung, die zwischen dem zweiten Element und der inneren Oberfläche des Fixierriemens angeordnet ist. Die vibrierende Abstreifeinrichtung umfasst ein Abstreifelement mit einer Abstreifoberfläche und einen Antriebsmechanismus. Der Antriebsmechanismus erzeugt eine Vibration der Abstreifoberflächen und des Fixierriemens, wobei die Vibration des Fixierriemens hilft, eine Trennung der Medien, die den Walzenspalt durchlaufen haben, von der äußeren Oberfläche des Fixierriemens benachbart zu der Abstreifoberfläche und des Abstreifelements zu erreichen.

Abstract: The appts. combines an ultrasonic cleaner and hard blade sliding on the photoreceptor surface to remove the toner additive film. The blade scrapes the toner additive film (30) and residual toner off the photoreceptor (10) simultaneously. The cleaner and blade control the thickness of the ZnSt layer for reduced friction and enhances transfer, maintaining its thickness at less then 50Å. The ultrasonic cleaner (80) is located opposite the blade. It has a vacuum to hold the photoreceptor in contact with the tip of the cleaner (81). The tip has a velocity from 1500 mm/sec to 3000 mm/sec. Alternatively the tip remains in contact with the photoreceptor and there is no vacuum.
