Abstract: A system and method of stacking printed sheets with sheet curl stacking problems in an automatically variable configuration stacking system having a spaced array of repositionable initial sheet supporting surfaces providing a generally planar initial stack supporting configuration on which a limited amount of sheets initially stack, and then, in response to stacking additional sheets in said system, the stacking system automatically changes to a different, arcuate, stack supporting configuration by automatically lowering at least some of the spaced array of initial sheet supporting surfaces to arcuately bend the curled sheets in an arcuate direction transverse the sheet curl direction on a fixed stacking surface that is arcuate transversely of the sheet curl direction.

Abstract: A sheets sets compiling and stacking system for the output of a printer, in which the seriatim output of printed sheets may be accumulated and neatly stacked on a temporary sheets supporting system until the desired number of sheets for that set (e.g. all the pages of a collated document) is accumulated (compiled). The temporary sheets supporting system may then automatically open to drop each completed or compiled set of sheets, but with positive alternate side set clamping control against sheet scattering or skewing, dropping only one side of one set at a time, by a short distance, down onto a multiple sets stacking system, such as a self-lowering elevator stacking tray, so as to provide reduced set scattering or skewing of the sheets within the sets, and/or between sets.

Abstract: A printing machine having multiple distributed high voltage power supplies is disclosed. The printing machine comprises a print engine having a plurality of high voltage electrical printing machine components. A housing supports at least one of the high voltage power supplies. A receptacle mounted on the housing receives an external connector from one of the machine components. The receptacle is fixed on the housing and is not detachable. A contact located inside the receptacle electrically connects circuitry from the power supply to the external connector. A second contact on the housing electrically connects circuitry from the power supply to a second external connector on the machine component.

Abstract: A lightweight easily installed shield for a corona generating device. A frame to support the end blocks and provide a structural member for a corona generating device is provided. The shield for the corona generating device is made of a lightweight, thin conductive material such as stainless steel and are formed so that they have a generally bowed out cross section prior to installation in the frame. To install the shield in the frame it is squeezed together and inserted in the frame. Once released the resilient bias of the steel causes the shield to be restrained within the frame and can be accurately located and retained by using a locating pin or ridge formed in the frame. The shield described allows easy and accurate assembly of the corona generating device.

Abstract: A tension support mounting for applying tension to the corona generating electrode of a corona generating device. Various embodiments are described wherein the corona generating electrode is fastened to a mounting block including an electrode support member, the position of which can be varied for applying variable tension to the corona generating electrode.
