摘要： A paper conditioner to control image dependent curl in a copier/printer includes a reservoir for storing a quantity of liquid, a pair of rolls in contact with one another so as to define a nip, and a metering roll associated with the reservoir and one of the pair of rolls. The metering roll forms a nip with one of the pair of rolls to direct a controlled flow of liquid from the reservoir to the nip area. Seals located at opposed ends of the metering roll and the roll with which it forms a nip prevent the flow of excess liquid from the ends of the metering roll.

摘要： A paper conditioner to control image dependent curl which uses one or more counter-rotating transfer rollers which are initially spaced from their respective back-up rollers in the intercopy gap, and which come together as the lead edge enters the nip area, and separates when the trail edge is about to pass. This permits the rollers to have a less demanding runout tolerance by bringing the rollers together when the sheet is in the nip, and then articulating the rollers apart in the intercopy gap.

摘要： A bottom sheet feeding system for feeding individual image substrate sheets for reproduction apparatus out from under a stack of such sheets by intermittently feeding the bottom sheet out from under the overlying stack of sheets in a sheet stacking tray with a bottom sheet feeder, which may be electrostatic, while that stack of sheets is intermittently at least partially levitated relative to the bottom sheet to substantially reduce the gravitational force of the overlying stack of sheets normally bearing down on the bottom sheet to resist the separation and feeding of the bottom sheet out from under the rest of the stack. This intermittent stack levitation may be accomplished by appropriate cyclical transducer system forces applied to the bottom of the stacking tray at a frequency coordinated with intermittent feeding of the bottom sheet out from under the stack.

摘要： A non-contact optical sheet size and/or position detection system for detecting the position of at least one edge of an outside (top or bottom) document sheet stacked in a sheet stacking tray in which thin document sheets of different sizes and/or positions are stacked on top of one another; with an illumination source for illuminating the potential sheet edge areas at an angle generating detectable sheet edge shadows, and an optical detection system remotely detecting the edge shadow positions to provide sheet edge location information to a control system for the imaging or offsetting of the sheet. In a document feeder for sequentially feeding a top or bottom sheet to be imaged, the detection system may be responsive only to a moving sheet edge shadow to determine the size of the sheet being fed to be imaged relative to other sheets in the stack irrespective of intermixed different sizes of sheets in the stack. For a bottom feeder the detection may be through an elongate aperture in the tray. For an output stacking system with a system for offsetting alternately printed sets of sheets in a stacking tray the detected edge shadow(s) of the top sheet may be used to control the offsetting.

摘要： In a document reproduction apparatus with an imaging station and a sheet feeding system for feeding physical document sheets in a sheet feeding path at a first velocity in a document sheet motion direction to the imaging station to be imaged, with a transmissivity sensor for measuring the transmissivity of the document sheets to provide an imaging control signal for reducing show-through imaging defects from light transmissive document sheets including opposite side images of duplex documents, there is provided a document sheet light transmissivity measurement system with a scanning system for linearly moving a single scanner on a single axis at a second velocity across the sheet feeding path orthogonally of the document motion direction in coordination with the document sheet movement at the first velocity so that the scanner diagonally scans the document on two axes before the document is imaged, to provide a more accurate transmissivity measurement of the document sheet than a single axis transmissivity scan, preferably with a ratio of these first and second velocities equal to the ratio of the side and end dimensions of the document being scanned to scan diagonally across the document from one corner to an opposite corner and thereby scan into all four of the possible unprinted edge margins of the document to obtain an imaging control signal therefrom.

摘要： A system and method of automatic signature printing for a copier, in which a job set of plural conventional non-signature document sheets in a normal collated page order are reordered into a signature printing page order, placed into the document loading tray of a recirculating document handler (RDH), and presented to the imaging station of the copier by the RDH, for producing plural image signature copy sheets from the copier suitable for folding and assembling into signature set booklets of proper page order; wherein the job set is initially as one stack in an automatic job loading system but with a specified approximately one-half of the document sheets being loaded in a face up orientation, and the others being loaded in a face down orientation. The document sheets are sequentially fed by a single feeder into the semiautomatic loading entrance of the RDH, and automatically loaded into the document loading tray of the RDH, with or without an inversion, corresponding to the initial job stacking orientation, so that they now have a common orientation, but are reordered into a signature printing page order, in which they may be normally circulated by the RDH for automatic signature printing. Special processing is provided for automatically inserting the requiste 1, 2 or 3 blank pages at the correct location on the signature copies for any size of job set. Also, for precollation signature copying with a duplex buffer tray copier. Automatic recollating of the job set after copying is also provided.

摘要： A sheet reversing mechanism having drive rolls independently activated for driving sheets into and out of a sheet reversing station at different rates. A first shaft supports a drive roll engaging an idler roll supported on a second shaft and a drive roll supported on the second shaft engages an idler roll supported on a third shaft. The diameters of the idler roll and the drive roll on the second shaft are different providing corrugations in sheets driven out of the reversing station.
