Abstract: In one embodiment of the present invention, a modular printing system has a plurality of modules for processing sheets. One module is a collator module configured to retain the sheets. The collator module has a collator controller and sensors linked to the collator controller. The sensors are arranged to detect erroneously processed sheets. The collator controller is configured to generate an error signal in response to detection of an error. The collator module also includes a feed assembly for presenting the sheets. A printer module is configured to receive sheets presented by the feed assembly. The printer module includes a printer controller and sensors linked to the printer controller. The sensors are arranged to detect erroneously processed sheets and to generate an error signal in response to detection of an error. The module printing system also includes a system controller linked to the collator controller and the printer controller.

Abstract: The document handling apparatus provides support structure and a plurality of retainers supported by the support structure. Each retainer includes a tray that is configured to hold a stack of sheets. A feed assembly is supported by the support structure and is substantially vertical and has a mid-section. The feed assembly defines an output port configured to output the sheets. The output port is approximate the mid-section so that the average distance from the retainers to the output port is substantially minimized. The apparatus further includes a plurality of pick mechanisms. Each pick mechanism is configured and arranged to pick sheets from one of the retainers and feed the pick sheet into the feed assembly. The apparatus can include an adjustable edge guide pivotally supported by the support structure. The adjustable edge guide is arranged and configured to control the side edge of the stack.

Abstract: A document (or medium) collating/printing system provides automated error detection and error recovery in a high-volume printing application. The system includes a media transporter for transporting the print media, a collator having a plurality of retainers for holding groups of document types, and a printer arrangement that receives and processes presented sheets of the print media from the media transporter. The printer arrangement and the media transporter are configured and arranged to form a substantially planer path for transporting the print media from the media transporter toward the printer device for printing on the print media. Further, a programmed controller controls the presentation of the print media to the media transporter and verifies that the presented sheet of print medium is correctly processed by the printer arrangement. Error detection and recovery are provided using selectively located sensors and diverters controlled by the controller.

Abstract: An autotaper for use in dispensing, cutting and locating tape.

Abstract: A fusing system for a xerographic printer in which the energy from a plurality of flash lamps is used to melt and fuse toner particles to paper sheets as said sheets travel through the fusing station. Each flash lamp has an associated storage capacitor and a charging circuit for that capacitor which is operative to develop a charge on its associated storage capacitor depending upon the length dimension of the paper sheets flowing through the system. Moreover, the capacitor charging circuits are rendered operative in a predetermined serial order so as not to unduly load down the alternating current source for the system. A lamp triggering circuit synchronized with the zero-crossings of the alternating current supply voltage provides the ignition potential for the flash lamps such that firing takes place at a time when the supply voltage is at a minimum.

Abstract: A computer-controlled machine for printing business documents, such as, checks, check vouchers, check registers and other forms used in quantity. Paper stock of varying dimensions, color or other characteristics is loaded into individual hoppers or trays in a paper input module. Under computer control, predetermined numbers of sheets are extracted from the plural hoppers in a prescribed sequence and transported, in proper alignment, to a first printing station where alpha/numeric characters are printed on the paper sheets by means of a non-impact xerographic printer in accordance with preprogrammed instructions. Next, the partially completed documents are serially transported, again in proper alignment, to a further printing station where MICR characters are impressed on the sheets using a drum and hammer-type printer, again with format, spacing and positioning controlled by a preprogrammed microcomputer system.
