Abstract: A machine uses electrophotography to produce panels of images for transfer to a continuous web of image receiving media. The images are transferred to the media under control of signals synchronized with media movement under a transfer structure which has a width sufficient to accommodate image transfer immediately prior to stopping of the media as well as immediately after restart of the media movement. The media is stopped with boundaries between sheets within the transfer zone.

Abstract: The contamination of machine components by a plasticizer such as dioctyl phthalate is controlled by placing a plasticizer absorbing/adsorbing member in the migration path of the plasticizer. The plasticizer may migrate with the airflow (airborne contamination) in a machine or through direct contact (conductive). The airborne contaminants such as dioctyl phthalate (DOP) tend to migrate from relatively warm heat producing components to cooler components of a machine. The airborne contaminants are trapped by an active DOP absorber disposed in the airflow path between the components. In a convenience copier, the airborne contaminants tend to condense on the photoconductor's surface. To this end, the active absorber/adsorber is placed in the airflow stream between various heat generating electrical components and the photoconductor's surface. In a connector, the contamination results from direct contact and is controlled by placing a plasticizer migration barrier in the migration path of the plasticizer.

Abstract: In a machine having a reciprocating original document handling carriage such as a copier, a selectively operable roller is positioned for removing documents from the upper surface of the carriage. The roller is driven by movement of the carriage by power stored from carriage movement or by an independent power source. Continuously driven rollers are positionable in coordination with the end of a run of copies for a given document to eject the document onto an output tray as the carriage returns.

Abstract: A document feed mechanism for feeding original documents to a copier imaging station. A bottom feed shingler wheel generates a shingled stack of original documents in a tray having a crowned shape, the tray crest being located forward of the shingler wheel. The shingled stack is supplied to a nip formed by an intermittently operated feed roll and a restraint roll which is rearwardly biased via a magnetic hysteresis slip clutch. The normal force on a sheet in the nip and the rearward bias force of the restraint roll are specifically controlled. The feed and restraint rolls intermittently supply single sheets to an imaging station feed mechanism.

Abstract: Sheets are delivered to receptacles by a traveling distributor which includes an incrementally movable carriage. A continuous loop belt or belts such as in a vacuum plenum transport convey the sheets to the carriage where a roller arrangement on the carriage diverts the belts and thus the sheets into a direction in alignment with the receptacles. The rollers then divert the belt away from the receptacles so that the sheets continue into the receptacles. The rollers are mounted so as to place the belt or belts in tension during normal operation but are movable to relieve the belt tension to facilitate paper removal from the belt in jam clearance procedures.
