摘要： A printing machine and apparatus are disclosed that include an ultrasonically assisted cleaning blade to remove toner particles from an imaging surface. An ultrasonic transducer is attached to the cleaning blade to provide vibrational energy to the cleaning blade. The ultrasonic transducer 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.

摘要： An ultrasonic transducer located under the photoreceptor belt provides vibrational energy to the surface to separate toner particles from the surface. The transducer is positioned such that it is located directly opposite the cleaning nip of the brush cleaner. The transducer reduces the adhesion of the toner to the photoreceptor surface, thereby allowing the brush to operate at reduced interference and voltage. The reduced interference and voltage results in toner being collected only at the very tips of the brush fibers thus, allowing more effective detoning of the brush.

摘要： An apparatus for efficient cleaning of the imaging surface. The primary cleaner is a rotating collection roll located directly opposite from and on the other side of the imaging surface from the ultrasonic cleaning assist device. 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, 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.

摘要： A cleaning apparatus and color printing machine having an ultrasonic cleaner and a cleaning blade is disclosed for removing residual toner, toner additive films, spots and comets off the imaging surface. The toner additives used during development leave more than one layer of toner additive films on the surface. An ultrasonic cleaner that has a tip velocity ranging from about 1500 mm/sec to about 3000 mm/sec is used in combination with a blade that has sufficient hardness to remove the thick toner additive films without damaging the surface. The build up of toner additive films cause copy defects. The vibrational motion of the ultrasonic cleaner reduces friction between the blade and the surface and enables the dislodgment of toner additive films, spots, comets and residual toner off the surface.

摘要： A method and apparatus for eliminating the accumulation of triboelectric negative toner that occurs between the cleaning edge of the cleaning blade and the photoreceptor surface. After image transfer, the residual toner particles on the photoreceptor surface are then charged to a uniform polarity using either a preclean corotron or a biased conductive blade. A UCA is used to dislodge the residual toner particles away from the photoreceptor surface. The polarity of the particles is opposite to that of the collection roll positioned to attract the toner particles levitated by the UCA onto the collection roll.

摘要： A cleaning apparatus having a spots cleaning blade to remove residual agglomerations of particles from the imaging surface. The spots cleaning blade is made from a material that has a low coefficient of friction, low resilience and higher hardness than a standard spots blade. These properties enable the spots cleaning blade to provide a continuous slidable contact with the imaging surface to remove residual particles therefrom.

摘要： A cleaning system for increasing the packing density of a sump fill. The cleaning system has a blade having an acute angle for removing residual particles from the photoreceptor surface. The acute angle of the blade creates a build up of toner and other residual particles on the cleaning blade. A support platen for the imaging surface is opposed to the cleaning blade to prevent damage to the imaging surface. The build up of toner and other residual particles is guided to the sump by a baffle causing tighter packing of the particles in the sump.

摘要： Apparatus for forming images on a charge-retentive surface including uncharged toner particles which are applied to electrostatic latent images formed on the surface. The latent image is formed on the charge-retentive surface by exposing a charged surface to a light pattern of an image to be reproduced. Prior to image exposure, the charge pattern comprises a periodic line screen pattern which is formed by means of a conductive charging brush having a suitable bias voltage applied thereto at a frequency suitable for forming the line screen pattern. By using such an arrangement charging and screening of the charge-retentive surface occur simultaneously.

摘要： An improved electrostatographic process wherein the imaging surface of the imaging member is treated with a lubricating effective amount of a compound selected from the group consisting of ortho-, meta-, para-phthalic acid, their corresponding metal or ammonium salts, and mixtures thereof. Controlled treatment of the imaging surfaces of the imaging member with the above compound(s) facilitates transfer of the developed image from the imaging member to a receiving sheet and removal of toner residues from the imaging surface upon cleaning. The imaging member element of the apparatus used in carrying out this process is covered with a thin film of lubricant over substantially all of its imaging surface thereby greatly improving toner transfer and removal.
