Nov 8, 2000

Appl. No.:

09/710135

Inventors:

Eric L. Andersen - Meridian ID
Paul K. Mui - Boise ID

Assignee:

Hewlett-Packard Company - Palo Alto CA

International Classification:

G03G 1500

US Classification:

399 87

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.

International Classification:

H04N 146

US Classification:

358 19, 358520

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*).

International Classification:

H04N 104

US Classification:

358488, 358497, 358498, 358496, 358475, 358474

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.

International Classification:

H04N 104

US Classification:

358474, 358497, 358488, 358498

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. A single sensor is utilized to detect the opening of the ADF which uncovers the contact glass to allow manual placement of a document. Detecting the opening of the glass plate cover is used to determine whether or not a document has been left on the glass plate after scanning.

International Classification:

H04N 104

US Classification:

358474, 358498, 358497

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. In systems wherein the automatic document feeder pivots to change the imaging system between its automatic feed mode and its manual feed mode, the cover actuating mechanism can be provided to move the scan window cover in response to the pivoting of the automatic document feeder, for example, by causing the scan window cover to slide in response to pivoting of the automatic document feeder.

US Classification:

399367

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.

International Classification:

G01C 1738

US Classification:

702 94

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.
