Method and apparatus for selectively scanning pages within a document stack
First Claim
1. A system for selectively scanning pages in a document stack, comprising:
- labels to be attached to one or more of the pages within the document stack;
a label sensor to sense a presence of a label on a page within the document stack;
a scanning system to capture images from the pages of the document stack;
a document handling system to enable pages from the document stack to pass over said label sensor and said scanning system; and
processor means, operatively connected to said label sensor and said scanning system, for preventing said scanning system from capturing an image from a page within the documents stack having a label attached thereto without interrupting a scanning process of a remainder of the document stack and for enabling said scanning system to capture an image from a page within the document stack that is without a label attached thereto.

Abstract
A scanning system enables a user to nondestructively mark certain pages in a document stack and cause these page to be skipped during the scanning on a digital scanner. The pages of the document stack to be skipped are marked with a small adhesive backed label placed at a pre-defined location on the page by the user. The label is large enough to carry a simple, but unique image (machine-readable code) that can be read by a single sensor. The machine-readable code may be a barcode, glyph, color pattern, or reflective/nonreflective pattern, etc. The label'"'"'s adhesive is such that it can be easily removed from the document stack without destroying the integrity of the page to which it was attached. In operation, the scanner utilizes a label sensor located before the scanning station/platen area so as to sense the skip label prior to the actual image capturing operation. Upon detection of the skip label on a particular document page by the upstream sensor, a microprocessor instructs the scanner to bypass the scanning of that page.

8. A system for selectively scanning pages in a document stack, comprising:
-
labels to be attached to one or more of the pages within the document stack, one label being printed thereon with a machine-readable code indicating a beginning of a skip operation; a label sensor to sense a presence of a label on a page within the document stack; a scanning system to capture images from the pages of the document stack; a document handling system to enable pages from the document stack to pass over said label sensor and said scanning system; and processor means for preventing said scanning system from capturing the image from the page having the label indicating the beginning of the skip scanning operation attached thereto and for preventing said scanning system from capturing the image from any page following thereafter when said label sensor senses the label indicating the beginning of the skip scanning operation.

9. A system for selectively scanning pages in a document stack, comprising:
-
labels to be attached to two or more of the pages within the document stack, one label being printed thereon with a machine-readable code indicating a beginning of a skip operation and the other label being printed thereon with a machine-readable code indicating an ending of the skip operation; a label sensor to sense a presence of a label on a page within the document stack; a scanning system to capture images from the pages of the document stack; a document handling system to enable pages from the document stack to pass over said label sensor and said scanning system; and processor means for preventing said scanning system from capturing the image from the page having the label indicating the beginning of the skip scanning operation attached thereto when said label sensor senses the label indicating the beginning of the skip scanning operation and for preventing said scanning system from capturing the image from any page following thereafter until said label sensor senses the label indicating the ending of the skip scanning operation.

10. A method for selectively scanning pages in a document stack, comprising the steps of:
-
(a) attaching labels to one or more of the pages within the document stack; (b) moving each page of the document stack pass a label sensor and a scanning system; (c) determining whether a label is attached to a page; (d) capturing an image from the page when it is determined that no label is attached thereto; and (e) passing the page through the scanning station without allowing image capture when it is determined that the label is attached thereto without interrupting a scanning process of a remainder of the document stack. - View Dependent Claims (11, 12)
