## Title
Delayed review of scanned documents using unique identification marking on scanned documents

## Abstract

A method and system include a computerized device operatively connected to a multi-function printing device. The multi-function printing device has a scanner, a media path, a printer, etc. The scanner scans a plurality of sheets of media to produce scanned images. The computerized device automatically stores the scanned images, and the media path automatically feeds the sheets of media from the scanner to the printer after the scanner scans the sheets of media. The printer automatically prints unique identification markings on the sheets of media after the scanner scans the sheets of media, such that each of the sheets of media has a different identification marking printed thereon by the printer. The computerized device automatically adds data representing each unique identification marking to each corresponding scanned image stored within the computerized device. When error images (e.g., ones of the sheets of media that were not scanned properly by the scanner) are identified, the computerized device automatically outputs the data representing each the unique identification marking for each of the error images, allowing a user to locate the sheet of media associated with the error image, to permit the improperly scanned sheets to be rescanned.

## Background
BACKGROUND
Embodiments herein generally relate to scanning systems and methods and more specifically to such where a printer automatically prints unique identification markings on the sheets of media after the scanner scans the sheets of media.
A fundamental issue with hallway scanners is review of the scanned documents. Hallway scanners are useful because paper documents can be converted to image documents near to where the document is received. Most commonly, these devices are packaged as part of a multi-function printer (MFP). Such systems allow one to scan a document using a nearby “hallway” scanner. However, reviewing these documents can be difficult. Two approaches have been provided for review. One is to print the scanned image for review, but this uses large amounts of paper (that is often discarded immediately after the review). A second approach is to display the scanned image on the local user interface; however, on many devices the user interface is small making review difficult. In both cases, the person who has received the document is responsible for reviewing the scan.
Another common scanning technique is to use a scanner directly connected to a computer. In this mode, paper documents are taken to an office (with such a computer and a directly connected scanner) and converted to image documents. When using this technique, the images can easily be reviewed on the nearby computer screen as they are scanned. However, this technique requires that all of the paper documents be scanned at one location. Collecting and delivering the paper documents to one location can be inconvenient.
In one example, a doctor may receive a document from a patient that must be entered into an Electronic Medical Record (EMR). In one situation, the doctor places the paper where it can be routed to the department where it will be scanned. The people in the department scan the document, review the image, and store the document in the appropriate patient's medical record. The problem with this approach is that the paper may be lost or the association with the patient may be lost. Alternatively, the doctor can scan the document on a hallway MFD and the image can be routed to the patient's record. The problem with this approach is the doctor is responsible to making sure that the scan is legible when the paper is scanned. To perform the review, the doctor must either use the local user interface on the MFD, which may be small, or print the image, which wastes paper. Also, since doctors are often rushed, the time to review the document may not be available.
SUMMARY
An exemplary system herein includes a computerized device operatively connected to (directly or indirectly connected to) a multi-function printing device. The multi-function printing device has a scanner, a media path, a printer, a document feeder automatically feeding the sheets of media to the scanner, etc. The scanner scans a plurality of sheets of media to produce scanned images. Before scanning, the sheets of media have some form of markings already printed thereon. The computerized device automatically stores the scanned images, and the media path automatically feeds the sheets of media from the scanner to the printer after the scanner scans the sheets of media.
A meta-data generator is operatively connected to the multi-function printing device, and the meta-data generator automatically generates unique identification markings. The printer automatically prints such unique identification markings on the sheets of media after the scanner scans the sheets of media, such that each of the sheets of media has a different identification marking printed thereon by the printer. The unique identification markings can be human-readable markings or machine-readable markings.
The meta-data generator also generates data representing each of the unique identification marking, and the computerized device automatically adds such data representing each unique identification marking to each corresponding scanned image stored within the computerized device. When error images (e.g., ones of the sheets of media that were not scanned properly by the scanner) are identified, the computerized device automatically outputs the data representing each unique identification marking for each of the error images, allowing a user to locate the sheet of media associated with the error image, to permit the improperly scanned sheets to be rescanned. In some cases, the computer can scan the images, automatically select ones that are bad, and automatically send email to a medical records clerk to search for the record. Embodiments herein can also automatically find original scanned documents. With a machine readable mark, the computer can find the paper that was scanned improperly by searching for the correct mark, if the marking is machine-readable.
An exemplary method herein scans a plurality of sheets of media using the scanner of the multi-function printing device to produce scanned images. The method can automatically feed the sheets of media to the scanner using a document feeder of the multi-function printing device.
Further, this method automatically stores the scanned images within a computer storage device that is operatively connected to the multi-function printing device. The method also automatically generates the unique identification markings and the data representing each unique identification marking using the meta-data generator, and automatically adds the data representing each unique identification marking to each corresponding scanned image stored within the computer storage device.
After performing the scanning, this method can automatically feed the sheets of media from the scanner to the printer of the multi-function printing device using the media path of the multi-function printing device. Some embodiments herein can have an entirely different paper path for adding the marks since they might be small requiring much less than the full scan printer. For example, a simple serial number stamp can be enough.
Then, after moving the sheets of media, the method automatically prints unique identification markings on the sheets of media using the printer. After printing, each of the sheets of media has a different identification marking printed thereon by the printer. After performing the scanning process, the method identifies the error images of sheets that were not scanned properly, (which could be manual or automatic) and automatically outputs, from the computer storage device, the data representing each unique identification marking for each of the error images.
These and other features are described in, or are apparent from, the following detailed description.



BRIEF DESCRIPTION OF THE DRAWINGS
Various exemplary embodiments of the systems and methods are described in detail below, with reference to the attached drawing figures, in which:
FIG. 1 is a schematic diagram of a system according to embodiments herein; and
FIG. 2 is a flow diagram illustrating method embodiments herein.



DETAILED DESCRIPTION
As mentioned above, when documents are scanned, they must be reviewed before the paper document (that was scanned) can be discarded. Current approaches provide either a print of the scan for review or display of the scan on a potentially small user interface on the multi-function printer. Also, these systems require the person who scanned the document to review the scan. Some systems do not require the person who scanned the document to review the scan, and instead send the scan to a remote reviewer; but if the scan is poor, finding the right document to be rescanned (which is stored at the scanning location) can be difficult.
With the embodiments herein, the multi-function printer automatically prints unique identification markings (sometimes referred to herein as “indicia”) on the sheets of media immediately after the scanner scans the sheets of media. Using the invention described here, a doctor can scan the paper on a local multi-function printer (skip the process of reviewing the scanned image) and directly route the image to the patient's EMR. In addition, a pointer to the scanned image is routed to a department responsible for checking the scan. The paper original is printed with indicia and stored in a hopper associated with the multi-function printer. Once all scans have been approved, the paper originals in the hopper can be destroyed; otherwise, the papers that need to be rescanned are easily located in the hopper because of the unique identification markings printed on the papers. The indicia can be human-readable markings (numbers, letters, etc.) or machine-readable markings (e.g., a bar code, glyph, etc.) for systems that automatically retrieve the paper copies from the hopper.
With embodiments herein, paper documents are entered into a scanner, where they are scanned, producing an image document. Meta-data is generated for the image/paper document pair in a meta-data generator and is printed on the scanned document. The meta-data generator can be a user interface at which the user enters information on the images, it can be a sequence number generator, or it can be part of a more complex routing system that indicates where the image document goes and other data. The meta-data generator can also use information from the scanned document. The meta-data is stored with the scanned image and printed on the paper document.
For example, the meta-data generator could include the patient number and a sequence number. A digital representation of these two numbers can be stored with the image document and a bar code and/or human-readable markings representing the numbers could also be printed on the document.
As mentioned above, the printer prints the meta-data on the paper document. If there is a location on the paper where there are no markings, such as a margin, the meta-data will be printed there. If there is no area on which the meta-data could be printed without obscuring data on the original paper document, the information can be printed using less visible ink such as ultra-violet ink or yellow ink.
The hopper contains paper documents that have been scanned. The documents could be arranged in the hopper to make them easier to find. For example, the paper documents could be arranged in sequential order. Alternatively, they could be grouped by slip sheets. For example, if a group of documents is scanned for a single patient, a slip sheet could be used to separate documents by patient.
FIG. 1 illustrates a computerized printing device 100, according to embodiments herein and can comprise, for example, a printer, copier, multi-function machine, etc. The printing device 100 includes a controller/processor 124, at least one marking device (commonly referred to as printers or printing engines) 110 operatively connected to the processor 124, a media path 116 positioned to supply sheets of media from a sheet supply 102 to the marking device(s) 110, and a communications port (input/output) 126 operatively connected to the processor 124 and to a computerized network external to the printing device.
An output tray/finisher (sometimes referred to herein as a “hopper”) 108 can simply receive the printed sheets, or can fold, staple, sort, etc., the various printed sheets. Also, the printing device 100 can include at least one accessory functional component (such as a scanner/document handler 104, graphic user interface assembly 106, etc.
The processor 124 controls the various actions of the printing device. A non-transitory computer storage medium device 120 (which can be optical, magnetic, capacitor based, etc.) is readable by the processor 124 and stores instructions that the processor 124 executes to allow the multi-function printing device to perform its various functions, such as those described herein. The input/output device 126 is used for communications to and from external devices connected by way of a network (wide area network, local area network, etc.). Such external devices can include, for example, one or more meta-data generators 130, external computer storages (device/medium) 134, and external computerized devices 132.
Pre-printed documents that are to be scanned can be loaded in the document handler 104, or can be loaded in the sheet supply 102. If loaded in the sheet supply 102, the documents to be scanned are fed along the media path 116 to an internal scanner 118, which scans the plurality of sheets of media to produce scanned images. Before scanning, the sheets of media generally have some form of markings already. There is nothing keeping one from scanning blank pages. However, there is usually no reason why one would want to. The computerized device 132 automatically stores the scanned images, and the media path 116 can automatically feed the sheets of media from the internal scanner 118 to the printing engines 110 after the internal scanner 118 scans the sheets of media (or this process can be manually performed). The same device that performed the scanning can also print the identification markings, or a different printer can be used to print the identification markings.
A meta-data generator 130 is operatively connected to the multi-function printing device, and the meta-data generator 130 automatically generates unique identification markings. The printing engines 110 automatically prints such unique identification markings on the sheets of media after the internal scanner 118 scans the sheets of media, such that each of the sheets of media has a different identification marking printed thereon by the printing engines 110. The unique identification markings can be human-readable markings, such as numbers, alphabetic characters, etc., or machine readable barcodes, glyphs, etc.
The meta-data generator 130 also automatically generates data representing each of the unique identification markings, and the computerized device 132 automatically adds such data representing each unique identification marking to each corresponding scanned image stored within the computerized device 132.
When error images (e.g., ones of the sheets of media that were not scanned properly by the internal scanner 118) are identified, the computerized device 132 can automatically output the data representing each unique identification marking for each of the error images, allowing a user to locate the sheet of media associated with the error image, to permit the improperly scanned sheets to be rescanned. Alternatively, a user (scan reviewer) can identify error images and note the unique marking of the error image to let the scan operator know which sheets need to be rescanned.
An output tray/finisher 108 can simply receive the printed sheets, or can fold, staple, sort, etc., the various printed sheets. Also, the printing device 100 can include at least one accessory functional component (such as an internal scanner 118/document handler 104, graphic user interface assembly 106, etc.
Thus, a printing engine body housing 100 has one or more functional components that operate on power supplied from the alternating current (AC) 128 by the power supply 122. The power supply 122 connects to an external alternating current power source 128 and converts the external power into the type of power needed by the various components.
As would be understood by those ordinarily skilled in the art, the printing device 100 shown in FIG. 1 is only one example and the embodiments herein are equally applicable to other types of printing devices that may include fewer components or more components. For example, while a limited number of printing engines, paper paths are illustrated in FIG. 1, those ordinarily skilled in the art would understand that many more paper paths, processors, databases, etc., and additional printing engines could be included within any printing device used with embodiments herein.
FIG. 2 is flowchart illustrating an exemplary method herein. In item 200, this method scans a plurality of sheets of media using the scanner of the multi-function printing device to produce scanned images. The method can automatically feed the sheets of media to the scanner using a document feeder of the multi-function printing device.
Further, in item 202, this method automatically stores the scanned images within a computer storage device that is operatively connected to the multi-function printing device. The method also automatically generates the unique identification markings and the data representing each unique identification marking using the meta-data generator in item 204, and automatically adds the data representing each unique identification marking to each corresponding scanned image stored within the computer storage device in item 206.
After performing the scanning, this method automatically feeds the sheets of media from the scanner to the printer of the multi-function printing device using the media path of the multi-function printing device in item 208. Then, after moving the sheets of media, the method automatically prints unique identification markings on the sheets of media using the printer in item 210. After printing, each of the sheets of media has a different identification marking printed thereon by the printer.
After performing the scanning process, the method identifies the error images of sheets that were not scanned properly in item 212, and automatically outputs, from the computer storage device, the data representing each unique identification marking for each of the error images in item 214.
