摘要:
A cleaning method and apparatus that provides lubrication to a secondary detoning roll (112) in a cleaner brush system, thus reducing cleaning failures. The toner particles removed from the first detoning roll (111) are transported to the second detoning roll (112). This allows lubrication of the second detoning roll (112) and reduces the wear problem of the second detoning roll (112) due to lack of lubrication.

Systems and methods of controlling banding defects on a receiving member in an imaging or printing process using a feedback and/or feedforward control technique. In one exemplary embodiment, a method of controlling banding defects on a receiving member in an imaging or printing process includes (S1220) determining a toner density on the receiving member, (S1230) automatically determining the extent of banding on the receiving member by comparing the determined toner density to a reference toner density value, and (S1240) automatically adjusting the toner density based on a result obtained from the comparison of the measured toner density to the reference toner density value, automatically determining the extent of banding and (S1260) automatically adjusting the toner density being performed using a feedback and/or feedforward control routine or application.
摘要:
Toner removal device for removing residual toner and debris from a charge retentive surface (10) after transfer of toner images from the surface. This device is characterized by the use of a pair of electrically biased detoning rolls (114, 120), one for removing toner from a biased cleaner brush (100) for recirculation and use and the other for removing debris such as paper fibers and Kaolin from the brush. Placement of the detoning rolls is selected so that the brushes are located adjacent natural oscillation nodes of the brush, and closely spaced to the position where the cleaning brush leaves contact with the charge retentive surface. Cleaning blades (150) for the detoning rolls are integrally provided with holders (152) for insertion into receiving slots (154, 156) in the cleaning housing (106). Extrusion sleeves are provided for insertion into toner transport devices for removal for cleaning.

摘要:
A cleaning brush (100) electrically biased with an alternating current removes discharged particles from an imaging surface (11). The particles on the imaging surface are discharged by a corona generating device. A second cleaning device (161,160,130) including an insulative brush (161), a conductive brush (160) or a blade (130), located downstream of the first mentioned brush (100), in the direction of movement of the imaging surface (11), further removes redeposited particles therefrom.

摘要:
An apparatus which cleans a moving imaging surface (10) with a cleaning blade (101) and automatically detects a failure of the cleaning blade. A failure sensing mechanism (170,180) detects the cleaning blade failure and activates a blade indexing mechanism (140). The indexing mechanism removes the failed cleaning blade (101) and positions a new cleaning blade in a wiping or doctoring mode frictional contact with the imaging surface for cleaning. A brush (110) positioned upstream of the cleaning blade, in the direction of movement of the imaging surface, disturbs the particles thereon.
摘要:
An apparatus for developing a latent image recorded on an imaging surface (10) with a custom color toner, including a developer housing (100) for developing a portion of said latent image with the toner of custom color. The developer housing (100) includes a donor member (42) for transporting toner of the custom color to a development zone (C) to develop the latent image. A replaceable reservoir unit (60) is provided for mixing and supplying the custom color toner to the donor member (42). An array of toner dispensers (66) is provided for supplying various primary color toners, as required, to achieve the custom color, and additional reservoirs (60) having various colored toners therein to allow for faster convergence to a given point in the color space.
