Abstract:
In association with a blade cleaning arrangement supported for chiseling removal of toner from a charge retentive surface, an auger is provided to move toner to the edge of the charge retentive surface and simultaneously simulate a foam roll cleaner, known to have good abrasive characteristics in the presence of toner. An auger member having a roughened or sharpened surface in contact with a charge retentive surface is arranged slightly upstream and adjacent to a blade cleaning arrangement for the removal of residual toner accumulating adjacent to a cleaning blade after release from a charge retentive surface such as a photoreceptor in a reproduction machine. The auger member may be comprised of a foam material providing an abrading surface roughness. Other augering members simulate the abrading qualities of the foam roll cleaner, such as for example, a sharpened auger edge which lightly scrapes the charge retentive surface, or an auger of a polymeric material, with a roughed surface.
Abstract:
Apparatus and method of determining the mass of an article by the shift of the period of oscillation of a flexibly mounted platform. An article whose mass is to be determined is placed upon the platform. The platform is caused to oscillate and the period of harmonic motion is calibrated. This period is compared against the period of harmonic motion when there is no article upon the platform, and the difference, or shift, in frequency, allows a determination of the mass of the article.
Abstract:
A processing station for use in electrophotographic printing machines to clean the photoconductive belt or develop the electrostatic latent image recorded thereon. A roller transports single component magnetic particles into contact with the photoconductive belt. The belt is deflected around the exterior circumferential surface of the roller to form an extended cleaning or development zone.
Abstract:
In a document feeder for transporting document sheets over the platen of a copier, with a vacuum belt platen transport system, into registration means for stopping the document sheet at an imaging position on the platen, wherein the vacuum belt platen transport system comprises plural belts moving under a white vacuum plenum backing surface overlying the platen, and includes a vacuum source for applying a partial vacuum to a document sheet being transported by the moving belts, the improvement wherein: the vacuum belt platen transport system belts are transparent or highly translucent thin, low-frictional, non-elastomeric, plastic belts; the transparent or highly translucent belts being unapertured and the vacuum plenum backing surface being unapertured in the imaging position, so that the vacuum belt transport system is effectively invisible through a document sheet to the copier. Additionally disclosed is a system for automatically reducing the level of the partial vacuum in the vacuum plenum for the transporting of a document sheet of greater than a predetermined size into the registration means, to avoid damage to the document sheet by the registration means, in response to means for prior detection of a document sheet of greater than a predetermined size.

Abstract:
An apparatus for feeding individual substrates from the top of a stack of substrates upon demand includes a first paddle wheel mounted above the substrate stack and adapted to forward a substrate from the stack in a predetermined direction and a second paddle wheel downstream from the first paddle wheel that is adapted to continue movement of the substrate in the predetermined direction. A friction retard roller is positioned opposite to and forms a nip with the second paddle wheel in order to inhibit multi-feeding of substrates. A second embodiment includes a single paddle wheel that acts in combination with a high friction surfaced guide member to feed substrates individually from a stack.
Abstract:
In a document handling apparatus for moving successive individual document sheets on the imaging surface of a movable vacuum belt into a copier imaging station, the vacuum belt has all its vacuum apertures limited to minor areas of the belt underlying the smallest document to be copied to avoid being exposed for imaging, but these apertures are pneumatically connected to a pattern of elongated airflow restrictive vacuum grooves which extend unapertured under and beyond the document edge over a much greater area of the belt surface. The grooves provide document vacuum retention in the unapertured belt areas from vacuum apertures opening recessed in selected minor areas of the grooves, and with reduced airflow requirements. These grooves have gently sloped walls and are otherwise designed to avoid reproducible shadows even where exposed.
