摘要:
There is disclosed a system for cleaning marking material from a surface portion of a movable photoconductive member. The system includes a first rotatable brush, a blade and a second rotatable brush arranged in sequential order along the movable photoconductive member. The first rotatable brush is for removing a first amount of marking material from the surface portion of the movable photoconductive member as the surface portion of the movable photoconductive member moves past said first rotatable electrostatic brush. The blade, in engaging contact with the movable photoconductive member, is for removing a second amount of marking material from the surface portion of the movable photoconductive member. The second rotatable brush, positioned in interference contact with the movable photoconductive member, is for removing substantially all residual marking material that was not removed by the first rotatable brush and the blade.

An apparatus for reducing electrostatic charge of particles in a waste container. In one embodiment the waste container is coated with a liquid having a viscosity sufficient to prevent tribocharging between the waste container and the waster toner particles, and to collect toner particles deposited from the cyclone separator into the waste container. Another embodiment describes the use of a flange extending into the waste container to prevent tribocharging that can cause explosions in the waste toner bottle.

A surface-treating apparatus has a dual-purpose surface-treating blade assembly that includes a blade holder for holding and loading a blade member, and a one-piece blade member having a first edge mounted to the blade holder and a second edge for contacting and treating a surface. The one-piece blade member has a mid-portion for applying a first edge-loading force to lightly contact and remove random spots from a central imaging region of the surface, a first end portion, and a second end portion. The dual-purpose blade assembly also includes a first shim device and a second shim device assembled respectively to the first end portion and to the second end portion of the blade member for stiffening such end portions and increasing a magnitude of each of a second and a third different edge-loading forces at such end portions relative to the first edge-loading force.

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. Additionally, an electrically conductive surface can be added to the front or back surface of the blade to cause toner particles to be repelled from and cloud near the blade where they can be removed by a vacuum device or the like. The conductive surface may be direct negative, direct positive or A-C potential to provide the necessary repelling force.

A cleaning apparatus that comprises a brush cleaner to remove particles from the imaging surface. The particles are removed from the brush cleaner using a detoning roll. The particles are loosened and separated from the detoning roll using a scraper blade. These loosened and separated particles, from the detoning device, are carried to a waste container by an air stream alone rather than using an augering system.

A flexible cleaner brush belt increases brush belt life by flexing away from the photoreceptor when not in use. The flexible belt is lifted away from contact with the photoreceptor and placed back into contact with the photoreceptor by a camming device. A camming device attached to linkages, increase the diameter of the flexible brush belt to lift the brush belt away from contact with the imaging surface. The camming device urges the belt brush back into contact with the imaging surface by decreasing the diameter of the brush belt. This movement of the brush belt increases the brush belt life and does not cause print quality defects, excessive toner clouding, or loss of machine productivity.
摘要:
A conductive flexible cleaner brush belt having a plurality of detoning stations to remove particles from the brush fibers. At least one of the rollers about which the flexible belt brush is mounted has a small diameter for spreading the brush fibers apart. This spreading of the fibers creates a node affect as the fibers rebound, adjacent fibers open creating a moving node affect. This node affect facilitates detoning of the brush by an air vacuum as air removes the particles from the brush fibers.
