Abstract: An apparatus and method for calibrating a peripheral device having a scanner and document feeder is provided. A target page is printed having a target at a known location on the page. The target page is then fed into the document feeder for scanning by the scanner. A calibration value is determined by determining the lateral position of the scanned target within the scanner. The calibration value is then used to adjust the lateral position of a scan line window width of the scanner to scan substantially only the entire width of a document page to be scanned.

Abstract: A portable memory medium with memory means, e.g., a magnetic strip or integrated circuit, for storing personal data and a language identifier that identifies a preferred language of an owner of the portable memory medium. For example, an automated teller machine (ATM) card includes a language identifier that indicates a preferred language in which the ATM card owner desires to have an ATM machine present a user interface in the preferred language. When the ATM card is inserted into the ATM machine, the ATM machine reads the language identifier from the ATM card, identifies a preferred language associated with the language identifier, and presents a user interface in the preferred language. A secondary language identifier may also be used in the event that the original language identifier is not recognized.

Abstract: A method and apparatus for an imaging device to automatically detect the presence of an automatic document feeder.

Abstract: Representative embodiments provide for an automatic document feeder including a housing and a cover supported by the housing. The cover and the housing are configured to define a storage compartment, and the storage compartment is configured to removably store at least one scan window, wherein the at least one scan window is configured for use with the automatic document feeder. A method of using the present invention includes storing a replacement scan window within a storage compartment, removing an existing scan window from an operational location of an automatic document feeder, retrieving the replacement scan window from the storage compartment, and installing the replacement scan window in the operational location of the automatic document feeder.

Abstract: A representative embodiment provides for an automatic document feeder apparatus configured for use in conjunction with an imaging device, and includes a feed guide supported in spaced overlying relation to a scan window of the imaging device. The automatic document feeder further includes a first document guide and a second document guide. The first and second document guides are supported in spaced relation to each other and are configured to guide a sheet media between the feed guide and the scan window. In use, the sheet media is the only element present between the scan window and the feed guide. Another representative embodiment provides for a method of automatically feeding documents, including guiding a sheet media into a gap that is defined by a scan window and a feed guide, and guiding the sheet media out of the gap.

Abstract: A single plate flatbed scanner utilizing a single sensor to detect both opening of a lid covering the plate and the leading edge of an automatically fed document. The flatbed scanner includes a contact glass plate defining a flatbed scanning area where a document to be scanned may be manually positioned. An automatic document feeder (ADF) scan window where ADF-fed documents are scanned is defined within the flatbed scanning area. An image sensor is maintained at a fixed position in the ADF scan window while scanning ADF-fed documents. To scan a manually fed document, the image sensor moves under the flatbed scanning area so as to scan an image of the document. Since the ADF scan window and the flatbed scanning area both are defined in the same area of the contact glass plate, a document inadvertently left on the contact glass blocks the ADF scan window and prevents the scanning of an ADF fed document.

Abstract: A scan window cover assembly in an imaging system includes a document feed system convertible between a manual feed mode, in which individual documents are placed manually onto a scan bed, and an automatic feed mode, in which an automatic document feeder moves documents over a scan window. The scan window cover assembly includes a scan window cover capable of selectively covering the scan window of the imaging system when the imaging system is in its manual feed mode, and can also include a cover actuating mechanism connected to the scan window cover. The cover actuating mechanism is adapted and constructed to move the scan window cover between a covering position blocking the scan window, and an open position outside the scan window.

Abstract: An image scanner is provided that includes a transparent platen for supporting a page during a scanning operation, an automatic document feeder and an apparatus for detecting if the page is present on the platen. The apparatus includes an indicium positioned above a predetermined area on the platen. In order to determine if a page is present on the platen, the predetermined area is scanned. If the indicium can be detected, then it is assumed that a page is not present on the platen. If, however, the indicium is not detected, then it is assumed that a page is present on the platen and the user may then be notified.

Abstract: An imaging system scans a color original and provides a signal with limited chromaticity for use by a print engine or a display. A light source illuminates the original with primary color intensities, for example 21% red, 72% green, and 7% blue. A sensor integrates the reflected intensities to provide a luminance signal. Matrix multiplication to convert to luminance is avoided. In a variation, illumination is provided with 6/19 red, 9/19 green, and 4/19 blue to provide a gray scale image of, for example, business graphics. Such an image has distinguishable variation for colors of equal lightness (L*).

Abstract: An apparatus and method for calibrating a scanner connected to a document feeder are provided. In one embodiment, the apparatus includes a calibration strip attached to a rotatable wheel assembly disposed within the document feeder. A cam is provided to rotate the wheel assembly and expose the calibration strip to the field of view of a head assembly of the scanner for calibration. The cam is configured to then rotate the wheel assembly in the opposite direction, so that the calibration strip is no longer exposed to the head assembly. A cleaning blade may be provided to wipe the calibration strip as it is moved to its non-exposed position.

Abstract: A combination printer/copier which utilizes the page sensor in the document feeder and/or the lid to trigger an interrupt sequence. The interrupt sequence queries the user for the interrupt copy job parameters. Once these parameters are entered, or the user accepts the default settings and initiates the interrupt copy job by depression of a single button, the interrupt sequence compares the interrupt copy parameters with the current job status and current job parameters to evaluate the current job for a possible stopping point. If possible, the current job is then stopped at this point and the current job status, as well as print parameters, are stored for retrieval after the interrupt job is completed. The interrupt job is then processed. Once the interrupt job is completed, the prior job status and print parameters are retrieved and the interrupted job is resumed.

Abstract: A first embodiment of an illumination source including red LEDs, green LEDs, and blue LEDs provides illumination for a scanner. The LEDs are arranged in an array to generate spectrally and spatially substantially uniform illumination on the surface of an object, such as printed media, which is to be scanned. The arrangement of LEDs includes a plurality of groups of three LEDs. Each group of LEDs includes a red LED, a green LED, and a blue LED. The LEDs of like colors are connected in series. Power is supplied to the three groups of series connected LEDs by three current sources. The three current sources are each configured to supply a constant current to one of the groups of series connected LEDs. Each current source supplies a magnitude of current so that the resulting light provides substantially uniform illumination on the printed media.

Abstract: A system and method for sensing a leading edge of a document in an imaging scanner includes detecting a shadow adjacent the leading edge, the shadow being cast as a result of the edge being exposed to a light source. Light is reflected off of a white drive roller support surface for the document and is sensed by a photo sensor array. As the document is processed through the scanner, the leading edge is exposed to the light such that the leading edge casts a shadow onto the drive roller. The shadow is sensed by the photo sensor array which sends a signal to a microprocessor for computing whether a threshold amount of shadow has been detected for initiating image scanning of the document. Prior to the medium being exposed to the light, a contrast sensitivity level of the photo sensor array is increased, relative to a normal level, for detecting the shadow.

Abstract: A laser printer provides a photoreceptor and a laser which produces an optical beam. A modulator is coupled to the laser and is responsive to binary data values to apply modulation signals to the laser to cause an image-wise modulation of the optical beam. Scan apparatus repetitively scans the optical beam across the photoreceptor to induce an image-wise charge state thereon. The scan apparatus causes, for one of the binary values, a variation in charge states corresponding to the one binary value across the photoreceptor. A function generator applies correction signals to the modulator to alter the optical beam in such a manner as to substantially prevent the variation of charge states. The function generator either causes a modulation of the voltage bias applied to the laser or modulates its pulse width output.

Abstract: A mirror and lens assembly which selectively places a mirror or other reflective surface into or out of the light path of an optical transducer in an optical data port to redirect incoming and/or outgoing optical signals and thereby permit data transfer from more than one general direction or position.
