Abstract: A method of printing personalized variable image requirements by (a) placing all print jobs with similar print image requirements into a particular group, all images for a specific entity in that group being a set; (b) printing images of each set in sequence of arrangement and in cycles, each cycle being a number of images up to the number of storage bins of a printing apparatus used for the print job; (c) storing the printed cycles in the storage bins until all sheets to the sets being stored there are completed; (d) unloading completed sets; repeating steps (b) and (c) if additional sets in the group require printing; (e) ending the print job if all sets for the group have been printed; (f) determining whether a next print job for another group is pending; (g) repeating steps (b)-(g)if a next print job is pending; and (h) ending all print jobs if no print job is pending.

Abstract: A solid-state selectably switchable combination cascade/magnetic brush for use in toner deposition or removal devices used in imaging machines of the electrostatic or magnetic type having one or more electro-magnets with one or more electro-magnetic windings and transfer heads placed inside, as well as outside, a photoconductor. Imaging mixture is agitated and conveyed to a transfer head which is exposed and adjacent to a photoconductor thereby eliminating the need for a drum or sleeve as the carrier/deposition agent for the imaging mixture. Transfer heads deposit imaging mixture directly onto a primary development zone with the excess cascading and attracting to a residual development zone and/or reclamation structure.

Abstract: A removable, sealable, magnet-less cartridge for use in a reproduction apparatus of the type having a control device to control the apparatus, a photoreceptor to receive toner through a photoreceptor path and to transfer the toner onto imaged portions of the photoreceptor, and a developer transporter of the magnetic type to carry toner in a magnetic brush to the imaged portions of the photoreceptor and to return unspent toner therefrom.

Abstract: An electrically self-propelled pulsating multi-directional magnetic brush having an insert for use in toner deposition or removal devices associated with imaging machines of the electrostatic type (dry or liquid), the magnetic type, and the reprographic type. The insert further has skewed magnetic sections, made of permanent magnets or electro-magnets, therearound. The insert is used in conjunction with a permanent or electro-magnet and is contained within a rotatably mounted drum to provide an insulation for the drum and to further provide a driving force to uniformly rotate and multi-directionally pulsate developer mixture material around the drum.

Abstract: A modular copier/printer or similar image forming apparatus of the type having an image transfer body in the form of a drum or belt allows documents to be reproduced in a paper discharge mode which discharges paper sheets, or recording media, in page-sequential order. When an automatic two-sided copy mode is selected, the apparatus automatically sets up the page sequential paper discharge mode to a "collation mode" through a minimum number of sorter bins which has been optimally designed to correspond with the shortest two-sided copy loop. Hence, when mixed black-and-white documents and color documents are reproduced together in the automatic copy mode, paper sheets exit the apparatus in the correct page order. As a result of this automatic change in operating modes, fewer "skip" frames need be introduced during the copying operation, thereby enabling the copier to produce multiple collated copies of the multipage document very efficiently.

Abstract: An electrically switchable magnetic brush for use in toner deposition or removal devices used in imaging machines of the electrostatic type. When energized by a multiphase alternating current power source or a brushless direct current power source rotatably mounted drum (9) requires no external driving force and is self-propelled.

Abstract: The present invention is a machine control having a programmable non-volatile memory and microprocessor to control power to a fuser lamp in a manner to adapt the machine to distinct power outlets. The non-volatile memory is programmed to indicate the availability of a particular power output. The control monitors the memory and in turn gates a triac controlling the fuser lamp to apply the maximum possible power to the fuser. If the machine is operating at a 3.0 of a 2.2 kva outlet, full power could not be delivered to the fuser while the machine is operating. The machine would adapt to operate at reduced power to the fuser until the fuser temperature drops below a minimum temperature level.

Abstract: A system of pre-collation copying a set of duplex document sheets by inhibiting the operation of a document inverting path during successions of contiguous plural document copying circulations to copy only one side of the documents during each succession, and actuating the document inverter path only during single document circulations at the end of a succession, after the document set has been circulated a number of times in that succession equal to the quotient of a constant number divided by the number of document sheets in the document set. Opposite sides of the documents are copied in alternate successions, and all the copies made during every other succession of plural recirculations are temporarily stored in a buffer set of a pre-determined maximum desired copy sheet capacity. The constant number corresponds to this copy sheet capacity.

Abstract: An improved copier control system in which pre-printed and operator marked control sheets otherwise corresponding to the regular original document sheets being copied are fed together with those regular documents by the copier document feeder past an optical scanner connected to the copier controller. The document sheets are copied in the manner instructed by the preceeding control sheets, without requiring manual switch inputs, while the copying of the control sheet itself is automatically inhibited.
