摘要： A piezoelectric transducer (PZT) device (104) operating at a relatively high frequency is coupled to an imaging surface to cause localized vibration of predetermined amplitude, and is positioned in close association with a cleaning enhancing electrostatic charging or discharging device (102, 200) associated with the imaging surface cleaning function, whereby residual toner and debris is fluidized for enhanced electrostatic discharge of the toner and/or imaging surface, and released from the mechanical forces adhering the toner to the imaging surface.

摘要： An electrically biased cleaning belt brush (110) removes oppositely biased particles from a surface (10). The belt brush (110), which is entrained about supporting members (112,114,116), includes a substrate to which is attached a multiplicity of conductive brush fibers. Electrical biasing means electrically biases the belt brush (110) with alternating regions (181,183) of points and negative polarity. Particles adhering to the conductive fibers are removed from the brush fibers at a detoning station (118).

摘要： 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.

摘要： An apparatus for cleaning particles from a surface (11) in a printing machine that includes a blade (100) and a vibrational apparatus (150). The blade (100) has a fixed end and a free end opposed to one another. The free end contacts a side of the surface forming a cleaning edge to remove particles from the surface. The vibrational apparatus (150) is positioned opposite the blade (100) with the surface located between the blade and the vibrational apparatus. The vibrational apparatus reduces friction and lowers the level of blade force required between the blade and the surface to prevent tucking of the blade.

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.
