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.

摘要： A method for determining a location on an image bearing surface of an image printing system where a toner image is to be printed is provided. The method comprises generating a first signal from a detector that is configured to detect a reference mark on the image bearing surface, and a second signal from a clock system that counts incremental movements of the image bearing surface, determining a first value that correlates the first signal and the second signal, where the first value corresponds to a value of the second signal at a start of characterization of the image bearing surface, and determining a second value using the first value, where the second value provides the location on the image bearing surface where the toner image is to be printed.

摘要： Diagnosis of servo motor driven drive train problems based upon changes in the rotational velocity of the servo motor as electrically operable drive line components are selectively engaged. The unloaded (unloaded) rotational velocity of a servo motor is determined, a drive train component that couples a load to the servo motor is energized, the change in the rotational velocity of the servo motor caused by engaging the drive train component is determined, and, if the servo motor rotational velocity falls outside of a predetermined limit the drive line fault that causes that rotational velocity to fall outside of that limit is identified. Beneficially, the status of the drive train is sent to a remote location using a data link.

摘要： Scanner fault recovery in an electronic reprographic system includes monitoring the scanner for faults and enabling deletion from memory any images corresponding to documents involved in the scanner fault. Once the images have been deleted, refeed instructions are displayed to the operator for refeeding the documents whose images were deleted. Upon document refeed, the documents are rescanned for completion of scanning of the job.

摘要： A method of locating the position of an object on the platen of a raster input scanner having a movable scan carriage and an extended array of scanners is disclosed. The method includes the steps of obtaining a previously stored theoretical position of the object from a memory, locating the scan carriage at a position spaced a predetermined distance from the previously stored position, moving the scan carriage toward the previously stored position while operating at least some of the scanners until a target on the object is detected by the operating scanners, and storing a target position of the scan carriage where the target is detected. The target position can represent the location of the scanner's calibration strip or the registration position of a document. After the target position is stored, the scan carriage can be located at the target position for calibrating the scanners if the target position represents the location of the calibration strip. Alternatively, the scan carriage can be located at the target position prior to actuating the scanners for each subsequent document to be scanned if the target position represents a document registration position. This procedure is repeated to determine the document registration positions for documents which are placed on the platen manually, by an SADH or SALDH input, by a CFF input, or by an RDH input.

摘要： A method and apparatus for document feeding for improved operator document manual insertion in which a document may be manually initially inserted into a document input area and released. The document is sensed in the document input area by a document sensor, and then automatically clamped in a document feeding nip which is automatically actuated in response to the document sensing, and then the document is automatically fed. Here, a first time delay period is provided between the sensing of the manually inserted document and the automatic clamping of the document. A second time delay is provided between the automatic clamping and the automatic feeding of the document. Preferably the automatic clamping of the document in the feeding nip is with a limited initial nip force sufficiently low to allow manual document retraction without document damage during the second time delay period. Furthermore, preferably the document sensing automatically actuates an operator display, but here a substantial present time delay is provided between the sensing of the manually inserted document by the document sensor and the automatic actuation of the operator display.
