摘要： The present invention is a method and apparatus for selectively altering the sensitivity of an optical sensor. The sensor has both a light source and a detector which are optically aligned with one another. The detector produces a first output signal level in response to light having an illumination intensity greater than or equal to a threshold intensity, and a second output signal level in response to light having an illumination intensity less than a threshold intensity. The sensor further includes the ability to selectively alter the illumination intensity of the light emitted by the light source to a lower level between the threshold intensity and the normal operating intensity. Hence, operating at the lower intensity enables the sensor to detect translucent sheets or facilitates identification of marginally operable sensors.

摘要： A sheet handler for successively transporting sheet-like material units to and from processing stations in image processing devices such as printers, copiers, and scanners. The sheet handler includes an idler and driven cross-roller set. The rollers are preloaded so that a normal force exists between the rollers at the nip. The nip is positioned in a path for receiving the sheet like material units and to urge such units along the path and into alignment along a registration edge. Apparatus for adjusting the preloaded force are provided to thereby adjust the normal force on sheet-like material passing through the nip.

摘要： An air knife pressure calibration system and method for a bottom vacuum corrugation recirculating document feeder includes measuring the air pressure and adjusting an air pressure control valve of the air knife to a predetermined value. This valve position is stored in a non-volatile memory and can be used to create a table of values for various document stack heights by adding constant values that represent additional documents to the one document value. Thus, customized valve positions are accomplished that are machine as well as altitude sensitive.

摘要： In an automatic document handling system for a copier, with a system for feeding and registering document sheets, including a platen transport system, wherein the platen transport system includes a document belt system and a vacuum system for retaining documents against the document belt, there is provided common document input and path systems for feeding either conventional document sheets or computer form or other web (CF) documents, the document belt system relatively low friction belt material, the vacuum system automatically maintaining a first vacuum level high enough to retain the conventional document sheets against the document belt system with sufficient force to resist slippage and function as their primary platen transport system, and a vacuum reduction system for automatically reducing the vacuum to a substantially lower level for CF documents which provides for slippage of CF documents relative to the document belt system, and a separate deskewing and driving system for the CF documents in cooperation with the platen transport system, for deskewing the CF web upstream of the platen and pulling through the platen transport system from downstream thereof, to provide a dual mode system in which the platen transport system provides for low frictional relative movement and an imaging background surface for CF documents, but is not their primary transport. There is a system for automatically sensing the acquisition of CF documents and in response automatically reducing the vacuum level and disengaging additional roller drive systems in the path which normally engage conventionally document sheets.

摘要： A fade-out system for a copier with a document feeder, for preventing the undesired development of areas of the photosensitive imaging surface relative to the desired latent images of the document with a variable magnification optical imaging system, preventing "show around" copy defects from the document feeder, where the document feeder transports the document sheets in a document path onto and over the copying platen of the copier. An array of plural document sensors is positioned in the document feeder for measuring both the length and width of the document sheets being transported onto the copying platen, and the fade-out system connects with and is controlled by both the array of plural document sensors and the magnification setting of the optical imaging system for preventing development of any areas of the photosensitive imaging surface outside of the latent images of the documents irrespective of the size of the document sheets or the magnification setting. The array of sensors is adjacent the platen and in the document path from both of the document sheet inputs to the platen. The fade-out system is further responsive to the actual size of the copy sheets on which copies are being made, for automatic flood illumination of areas of the photosensitive imaging surface outside of the smaller of the two of the document latent image area or the actual copy sheet size, by fading out any portions of the document latent image area which will not be engaged for image transfer by the copy sheet, and fading out otherwise developable nondocument latent image areas of the photosensitive imaging surface even if they are within areas of the photosensitive imaging surface which will be engaged by the copy sheets, so as to provide complete fade-out for any selected magnification or document size or copy size.

摘要： A method of more efficiently copying with a copier with a recirculating document handler for making plural precollated plural sheet copy sets from a set of plural document sheets being plurally recirculated; wherein the set of document sheets being recirculated has at least two document page images per document sheet side, producing copy sheets with at least two images per side from these document sheets, and the copier control is selectably modified to separate the copy sheets into at least two separate sub-sets of output copy sets having a number of sheets corresponding to the number of document page images per document sheet side, with the number of copy sub-sets being at least twice the number of the document sheets being recirculated in the document handler, and separately binding the output copy sets into the separated collated sub-sets in response to the modification of the control means with automatic on-line binding; including known, conventional, on-line paper slitting or cutting of the copy sheets for the separating of the copy sheets into the separate sub-sets.

摘要： A sheet feeder is provided comprising at least two drives that drive a sheet of material along a paper path and at least two sensors that detect a lateral side of the sheet of material. A controller is connected to the two sensors and at least one of the drives. The controller varies the drive velocity of at least one of the drives to shift the lateral position of the sheet of material in a predetermined direction until one of the sensors detects the lateral side and then varies the velocity difference of the two drives to eliminate the skew of the sheet.

摘要： A ball-on-belt transport includes a belt with a steel ball positioned on top of the belt and a magnet on the back side of the belt with the ball forming a nip with the belt to provide necessary normal force against a conveyed sheet and thereby allowing easy lateral pulling of sheets in clearing jams from the nip. Alternatively, a steel ball is retained while in contact with a belt to apply a normal force to a sheet on the belt equal to the weight of the steel ball. The ball is encased in a housing that is surrounded by a solenoid coil such that when current is applied to the coil, it acts as a solenoid and raises the ball off the belt surface and thus releases the nip pressure.

摘要： A top vacuum corrugation feeder includes articulating suction fingers to assist in raising the top sheet of a stack of sheets to the feedhead of the vacuum corrugation feeder. The suction fingers are rotated down from their interleaved position between feed belts to contact the top sheet in the sheet stack and raises the top sheet to the feed belts. As a result, the feeder can handle heavy sheets, curled sheets, and sheets which are edge welded.
