摘要： An illumination output from a fluorescent lamp used in a RIS type scanner is maintained at optimum by monitoring the lamp's on/off state and turning the lamp on for a time period following a specified cumulative off time. In one example, the lamp is turned on for a two minute interval following a one hour off time. Following the two minute on period, a diagnostic test is automatically performed to determine whether variations in the lamp output have resulted in an out of specification condition requiring that the lamp be recalibrated to the photosensor array. The calibration is automatically enabled by adjusting the gain of the photosensor array until the photosensor response is within the nominal percentage range. The scanner is then returned to a standby mode. All of the tests are performed automatically and normal operations can be accomplished while the lamp is in warm up phase.

摘要： A diagnostic test process is provided for a visual verification of the spatial illumination characteristics of an illumination system used in a raster input scanner (RIS) system. A calibration reference strip is illuminated by the RIS scanning lamp and the reflected image is detected by a photosensor array. The output data from the photosensor is sampled at predetermined time intervals with each sampling being displayed as a video illumination profile at a display screen. The profile is superimposed on a calibration grid with indicia which allow verification that the lamp calibration is still valid. An out of spec calibration display prompts an operator or tech rep to initiate a recalibration routine or to replace the lamps or possibly clean the optical system components.

摘要： An electronic reprographic apparatus, including a method for increasing the speed of manual or semi-automatic imaging of signature-type original documents, having the ability to selectively control the areas of the documents to be imaged. In particular, the system enables the user to identify the type of input document, including size and image cropping dimensions, thereby eliminating the potential for imaging beyond document edges or in bound document gutter regions. In addition, the system is suitable for scanning both page sides of a first signature-type document on the first pass of the scan array and is capable of scanning a second signature-type document on the reverse or return pass. Furthermore, the system implements the scanning operation with a center registration technique, facilitating the registration of bound documents.

摘要： An electronic printing system for scanning signature pages for signature jobs in which the pages of the document are placed face down in registered position on the platen of a scanner such that the signature images are side by side in the fast scan direction in order to enable an array to view both images concurrently on relative movement between the array and the platen in a slow scan direction.

摘要： A multifeed resistance system 90 which is a simple and low cost modification of known non-retard type bottom sheet separator/feeders, especially a vacuum feeder 17 in which the stack 14 of sheets is fluffed by an air knife 18 and the front area of the bottom sheet 98 is pulled down by vacuum and fed vacuum out from the bottom of the stack 14 with the corrugating vacuum belt feeder 17 and there fed out of the tray 16 from underneath the stack 14. A limited area of special multifeed resisting or retarding member 92 under the rear area of the stack 14 has been found to be effective in resisting multifeeds, yet not interfere with effective bottom sheet sequential feeding. One or more areas of the double feeding resistance member 92 overly the rear or upstream portion of the stack supporting bottom surface 15 of the stacking tray 16. This is an oriented (one-way) fiber mat, cloth or pad material, the fibers 94 of which are angled upstream (oriented towards the rear of the tray 16). These upstream oriented fibers 94 engage the trail or upstream edge area of the second-from-the-bottom sheet 96 to resist its downstream movement as the bottom-most sheet 98 is being initially separated and fed out.

摘要： A document handling system for sequentially feeding document sheets to be imaged with a controlled minimized interdocument gap therebetween even though the sheet separator-feeder sequentially feeds the documents from the stack in the input tray with initial interdocument gap variations to a second transport path portion feeding the document sheets through the imaging station at a constant velocity. A first servo drive feeds the documents in a first path portion including the separator-feeder, and a second servo drive feeds the documents in a second path portion providing the constant velocity. A sheet edge sensor in the first path portion signals the passage of the lead or trail edge of document sheets. A servo controller connecting with the sheet edge sensor and the first servo drive automatically measures the initial interdocument gap variations and change the feeding of document sheets in the first path portion so as to automatically changes the interdocument gap to a preset desired minimum interdocument gap in the second path portion. Preferably the second servo drive has an encoder generating signals proportional to its drive and the servo controller counts these signals between the passage of the trail edge of one document sheet and the passage of the lead edge of the next sequential document sheet past the sheet edge sensor, to calculate control signals for the first servo drive to drive it variably longer at a higher velocity than the second servo drive.

摘要： In a system for detecting and signaling the approximate size of a set, stack or job of document sheets, especially for a recirculating type automatic document feeder with a document set stacking and feeding tray for a copier or other document imaging system, in which an electromechanical set separator system provides rough initial stack height and therefore set size or document number estimation signals from the position of the set separator arm on the stack, and in which there is also a counter for counting the number of document sheets fed out from the tray; the advance estimation of the number of documents to be fed to be imaged is significantly improved by dynamically comparing the count of the number of document sheets fed out from the tray at and with the transition in the set size estimation signal from the set separator system.
