A toner removal apparatus for a reproducing machine has a cylindrical brush mounted for rotation in a closely fitting housing. The housing has an open side confronting a moving photoreceptor. Brush fibers extend through the housing open side into interfering contact with the photoreceptor and sweep toner therefrom. A slot in the housing parallel to the brush is connected to a vacuum source to draw air into the housing open side, through the brush fibers, and out the housing slot. First and second parallel bars are mounted on opposite sides of the housing slot and extend into contact with the brush fibers. The first bar compresses and then releases the brush fibers to flick toner therefrom. The second bar extends into the housing a lesser amount than the first bar and contacts the brush fibers without compression thereof, thereby providing an air seal, so that all of the air flows through the brush fibers.

A cleaning system and process for removing residual toner from an imaging surface, including a primary cleaner system for removing the predominant amount of residual toner and debris and a retractable secondary agglomeration cleaning blade mounted downstream from the primary cleaner, wherein, when the blade is moved into the engaged position, the cleaning edge is engaged with the imaging surface at for shearing release of agglomerations from the imaging surface and wherein the cleaning blade is movable to the retracted position during periods in which the primary cleaner is in its operative position.

A charged particles cleaning apparatus for cleaning and removing charged particles from a surface includes (a) a housing; (b) a surface scrubbing member mounted within the housing for contacting the surface and frictionally removing charged particles therefrom; (c) an air blower for pulling an air stream out of the housing; (d) a manifold connecting the housing to the air blower for directing the air stream and charged particles therein out of the housing, the manifold including manifold walls having inside surfaces defining a duct passage for the air stream; and (e) at least one biasing source connected to the inside surfaces of the manifold walls for biasing the inside surfaces to prevent build up of charged particles on the inside surfaces, thereby reducing costs of periodic cleaning of the manifold walls.

An apparatus includes a xerographic cleaning blade, an actuator member operatively connected to the cleaning blade and movable over a first stroke from a first actuator position to a second actuator position, and a damper operatively connected to the actuator member. As the actuator member moves over the first stroke the cleaning blade moves from a first blade position to a second blade position. The damper allows substantially uninhibited actuation of the actuator member over a first portion of the first stroke. The damper damps actuation of the actuator member over a second portion of the first stroke.

Systems and methods are provided for controlling cleaning devices in image forming apparatus electrostatic image forming apparatus. Such systems may include a charge receptor, movable in a process direction, defining a main surface. A toner application device applies toner to the charge receptor, and is configured to place a lubrication stripe including the toner on a portion of the main surface of the charge receptor at a selected time. An influence of a pre-clean corotron on the charge receptor is modified, during the designated rotations of the charge receptor, while the portion of the surface on which the lubrication stripe is formed, or will be formed, is passing the pre-clean corotron. The lubrication stripe is delivered to a secondary cleaning device including a blade engaging with the photoreceptor surface to lubricate the blade.

A diagnostic system that provides a service technician with service information during servicing of an image processing apparatus includes at least one counter that is incremented during operation of the image processing apparatus, a pressure detecting unit that detects a pressure at a point in an air flow path on the condition that the at least one counter is reset to zero after initial servicing of the image processing apparatus, a determining unit that determines whether a difference between the detected pressure and a fault threshold pressure is less than a predetermined margin, and a display unit that displays a fault code indicating additional servicing of the image processing apparatus is recommended on the condition that the determining unit determines that the difference between the detected pressure and the predetermined threshold pressure is less than the predetermined margin.

Aspects of the disclosure provided a method to improve performance of a cleaning device to extend a usage life of the cleaning device. The method can include obtaining a performance characteristic of an electrostatic brush that degrades operations of the electrostatic brush, determining at least one parameter that compensates for the degradation, and controlling the electrostatic brush by the at least one parameter to maintain the electrostatic brush operating within a failure boundary.
