Scan documents to pdf in one file. Scan documents to PDF

Scanning various documents has long become as commonplace in solving business problems as printing documents on a printer or typing text on a computer. Often you need to scan a document in order to subsequently send it to someone via e-mail. If the document is one or two pages long, then there are no problems with this. They appear when the number of scanned pages begins to count in the dozens.

The thing is that when you purchase almost any modern flatbed scanner, you do not receive with it the corresponding software that has wide functionality in the field of saving scanned documents. The software that scanner manufacturers include with their product is only capable of saving scanned documents individually in image format. Most often this format is JPEG or JPG. Less often PNG.
Thus, after scanning a multi-page document, you receive numerous image files, which, if you send to the recipient, you risk receiving disapproving comments about your document management skills and the accuracy of business processes. That is why it is highly desirable to combine individual disparate files into a single document that matches the structure of the original.

How to combine scanned documents into one file online
You can solve this problem very simply and quickly enough, even without installing additional software on your computer. software and especially without buying it. IN global network The Internet has many services that will help you combine several JPG images into one PDF file.

Finding such services is not difficult if you use any of search engines by entering the query “jpg to pdf” into the search bar. In this article we will clearly show the process of creating merged PDF service based file.
Converter on the website jpg2pdf.com to automatic mode performs optimization and scaling for each uploaded image, maintaining its original size and resolution. As a result, you get a PDF document so High Quality, how high quality the images you uploaded were.

The undoubted advantage of using online services Another advantage of merging scanned images is that they are cross-platform, meaning you do not need to search for and install the program on your Mac, or in the operating system Linux system. All that is required of you is just any modern browser on your computer and an Internet connection.

IN this document describes the creation of a multi-page PDF file for use in the program Adobe Acrobat Writer (or similar) using HP photo and imaging software.

Scan multiple pages without using the automatic document feeder (ADF)

Place the first page of the document on the scanner glass and open the HP Director software.

Click Scan a document

Select Text as images, Editable text or .

Save to file.

Click the Scan button. Click Accept if a window opens preview.

After scanning the first page as described in steps 1-5 above, you will be prompted to “Scan another page into the current document?” Place the next page on the scanner glass and click Yes.

To scan all pages, repeat the above steps. Click No after scanning last page. The Save As window will open.

Scan multiple pages using the ADF

Place the documents you want to scan in the ADF and open the HP Director software.

Click Scan a document. The Scan Document window opens.

Select Text or images as images, Text as images, Editable text or Editable text without images.

In the destination field at the bottom of the window, click Save to file.

Click the Scan button. If a preview window opens, wait until all pages are scanned and click Accept. If the preview window does not open, the Save As window will open after all pages have been scanned.

Scanning from Acrobat accepts images in the 10-3000 dpi range. When you select the option Searchable image or ClearScan in the PDF Output Style section requires an output image resolution of at least 72 dpi. In addition, output image resolution greater than 600 dpi will be reduced to 600 dpi or less.

Lossless image compression can only be performed on monochrome images. To compress the scanned image without losing quality, select one of the following options in the Optimization Options section of the Optimize Scanned PDF dialog box: following parameters: "CCITT Group 4" or "JBIG2 (lossless)" for monochrome images. If this image is added to a PDF document, you can save the file using the Save option; the scanned image remains uncompressed. When saving PDF document Using the Save As function, the scanned image can be compressed.

For most pages, scanning in black and white at 300 dpi will produce top scores for conversion. At 150 dpi resolution accuracy optical character recognition the number of font recognition errors decreases slightly and increases; At resolutions of 400 dpi and higher, processing slows down and the size of files with compressed pages increases. If the page contains many unrecognized words or the text is not big size(9 points or less), try scanning at more high resolution. Whenever possible, scan in black and white.

If the function Optical recognition characters is turned off, you can use a resolution in the range of 10–3000 dpi, the recommended resolution is 72 dpi and higher. For parameter adaptive compression Recommended scanning resolutions: 300 dpi for grayscale and RGB images and 600 dpi for black and white images.

Pages scanned in 24-bit color, 300 dpi, 8.5 x 11 inches (21.59 x 27.94 cm) before compression are large images (25 MB). System may require 50 MB virtual memory and more to scan an image. At 600 dpi, scanning and processing is typically four times slower than at 300 dpi.

Avoid adjusting the scanner's halftone and diffusion blend settings. This may improve appearance, but it will become difficult to recognize the text.

For texts printed on colored paper, it is recommended to increase the brightness and contrast by approximately 10%. If your scanner provides light filtering, you should suppress the background color using a special filter or lamp. Or, if text is not suppressed, try adjusting the scanner's contrast and brightness to clear up the scanned document.

If your scanner has a manual brightness control, adjust it so that the characters are clear and properly shaped. If characters are connected, use higher parameters (more bright color). If characters are separated, use lower settings (darker color).

Printers and scanners are fairly common types of office equipment. The need for them is extremely great, because it is necessary to photocopy a document or send information from a printer to a PC almost every day, especially when it comes to document management. In this article we will learn how to use additional useful features printer and scanner - learn how to optimally photocopy documents and scan them.

To photocopy one copy of your passport or scan an important document onto your computer, you don’t have to run to the nearest kiosk with a sign that says “photocopy-printout”; it’s enough to have it on hand modern device, which can copy information. Today, quite a lot of models support this feature. The printer has long ceased to be a device with functionality limited only to printing. Most often, a modern MFP is not only a printer itself, but also a scanner and a copier.

Most people can transfer scanned information to a computer. photocopiers, including both inkjet and laser printers. Today the question sounds a little different: what devices cannot make photocopies and send scanned information from the printer to the computer? Most often, the ability to print is limited to only the most inexpensive models printing technology. Any manufacturer produces models of different price category and, accordingly, capabilities, this is worth remembering when choosing such equipment. Medium and high product line price segment has a full range of capabilities.

To find out whether the device has a scanner and copier, it is best to look at its characteristics. However, sometimes it’s quite superficial study the body. If there is a cover on the top of the device with a glass surface underneath, then this device has the functions described above. The printer, as a rule, is equipped only with a receiving tray for blank paper and prints it vertically upward, whereas in an MFP the printed product comes out from the end, below the scanner area.

Important: if you are not sure about the capabilities of the device, it is best to study its documentation, which details each and every specification. By spending a few minutes studying the document, you can get much more more information rather than a superficial inspection of the device itself.

Learning to use the scanner yourself

Scanning is one of the most common procedures in office work; it applies to everything: documents, business literature, filing articles, photos, etc. It is difficult to imagine an enterprise that does not know what a scan is and does not use it in its daily activities.

At home in Everyday life A scanner is sometimes needed just as much, because... helps you quickly and easily digitize pictures, photographs and documents by transferring them to your computer. But even being a fairly common and familiar device, a scanner requires the right attitude. Do not attempt to use the device without proper training, as this may result in costly damage.

Preparing for work

So, to use the scanner, you need to follow a few simple steps.

Once the driver installation process is completed, the device is recognized by your operating system. It can always be found in the appropriate section (printers and faxes, etc.). Typically, the name of the device is the full designation of its model, including an alphabetic and digital index. If desired, the name can be changed to any other through the system settings.

After the process of installing drivers and synchronizing the device with the system, you need to decide what software you will use. The Windows OS family offers programs built into them by default, but this is far from the only solution. In any case, it is important to understand that without specialized program, which will be responsible for the scanning process, you cannot do without. It remains to choose from among the most popular: Adobe products, the XnView product line and the equally famous VueScan. Of course, the list of programs that allow you to scan is much larger, but those listed above are the most relevant.

Scanning

To check the capabilities of your scanner (and adjust it if necessary), in the interface any of running programs Click on the "file" option. Once it opens, look for “import”. If the last branch contains the full name of your device, everything is fine, it works properly. Next you need to do the following.

Once saved, your image remains digitized and will be ready for use at any time. It can be sent by mail, published on a website, or set as a background screensaver on your desktop.

Scan Options in Text or Photo Mode

Despite the fact that drivers from all manufacturers are different and do not have one universal scheme, there are a number basic settings, which are present in all devices without exception.

The first thing worth mentioning is this is DPI. When working with text, this item should not have a value below 300 (the same from a printer or MFP). The higher it is, the more accurate the picture will be. With a high DPI value, scanning will take a little longer, but the text is more likely to be readable, and you won’t have to resort to recognizing it. Optimal value 300-400 DPI.

The second thing you should pay attention to is color saturation(chromaticity). There are only three options here: the option of scanning black and white text, gray and color (magazines, documents, posters, etc.). The higher the color, the longer it will take to scan.

In photo mode the most important thing is to avoid blurring the picture, and also make sure that all edges lie flat on the surface. Color and tone are set in the settings options in preview mode before you start the scanning process from the printer.

It should be noted that for photo digitization, not only the scanning process itself is important, but also the process of post-processing of the finished material using specialized programs.

To scan photos, it is advisable to use maximum settings clarity, this will minimize possible inaccuracies during the process itself, although it will take 10-15 seconds more.

Making a photocopy on a printer

One of the most common office tasks- This is a photocopy of documents. You need to copy documents (passport, driver's license, etc.), important papers, books, notes. Learning to copy is quite simple; to do this, you need to adhere to the following algorithm of actions.

1. Make sure the device is connected to the network.
2. Check printer drivers.
3. Check the condition of the documents for dirt, wrinkles, wear and fingerprints.
4. Open top cover devices.
5. Carefully place the document there copy side facing down. Make sure that the paper lies exactly along the marks on the device.
6. Press the “start” button (on a printer and copier) or “copy”, if it is an MFP, and then “start”. Take the finished copies from the receiving tray, remove the source from the scanning compartment.

Important: the number of copies is adjusted in hardware using buttons (most often in the form of arrows).

The printer also has a number additional features. For example, you can make several copies of pages, fitting them onto one sheet of paper. How to do photocopy of passport on one page The easiest way to find out is from the following video:

What to do if the device does not scan

There are not many reasons why this happens.

Before taking the device to the service, try connecting it to another PC, installing drivers and scanning something. If this does not work, then the breakdown may be serious, and it is difficult to fix it with improvised means.

Techniques for operating scanners and MFPs

It is important to remember that a scanner costs money, and not little at that, so in order for it to serve you for as long as possible, you need to adhere to some rules. Where to start? Be as careful as possible when working with the glass coating - this is the most sensitive element of the scanner. If there are abrasions, scratches and dirt on it, this will certainly affect the quality of the digitized material. Periodically wipe the glass from dust with a soft material (for example, synthetic suede).

1. Whenever you are going to scan a document, make sure that the piece of paper is clean and free of dirt and dust. Under no circumstances should you scan dirty objects or use an abrasive.
2. Even if your device does not scan, do not rush to fix the problem yourself.
3. Do not press or press on the glass surface.
4. Never try to clean glass with powder or a lot of moisture, the former may scratch the surface and the latter may wet the electrics.

It is best to prepare the document to be scanned in advance. For example, if a document is not preserved in very good condition, then at high resolution all the flaws will be visible on it. Explore document status before asking required permission. Also make sure that there are no pieces of adhesive tape or other fastening materials (staples, etc.) on the piece of paper. If there are obvious fingerprints on the paper, it is best to remove them with an eraser or flannel cloth.

Learning to competently use all the capabilities of scanning and photocopying is not so difficult; you just need to show persistence and patience, and then any technique will obey you. If you are not confident in yourself, at the first stage it would be better to stick to simple instructions until you feel like you can use the scanner and photocopy yourself.

Scanning multi-page documents

In a programme ABBYY FineReader for ease of scanning process large quantity pages there is a special scanning process mode: Scan multiple pages which makes it possible to scan several pages in one cycle.

Additionally, when scanning via TWAIN using the FineReader interface, once a page is scanned, the scanning device automatically begins scanning the next page. When scanning through a custom TWAIN driver, your “Twain dialogue” with the program does not end: After the process of scanning the first page stops, you can simply put the next page in the “tray” and continue recognition.

In the ABBYY FineReader OCR system, you have the opportunity to scan a large number of pages in two ways:

Using the scanner's automatic document feeder.

Without using an automatic feeder.

Using the ADF

FineReader interface

In the dialog box Scanner settings(access: Service to Scanner Settings) activate the option Use ADF paper (ADF) and start scanning multiple pages (access: ).

TWAIN interface - scanner driver

In the scanner's own TWAIN dialog, activate the option Use ADF(the option may have a different name depending on the scanner model) and start scanning (access: File to Scan multiple pages).

Without using the ADF

FineReader interface

From the menu File select team

For the convenience of scanning several pages in a row on flatbed scanner without an automatic document feeder, set the pause value (the time from the end of the scanning process of one page to the start of the scanning process of the next). To do this, in the dialog box Scanner settings(access: Service to Scanner Settings) activate the option Pause between pages and set the pause value in seconds.

In this case, after scanning the first page, the scanner makes a pause specified by you, during which time you should have enough time to place another page into the scanning device. Next, scanning will continue in automatic mode.

How to “relax”

Try it in the dialog box Scanner settings(access: Service to Scanner Settings) activate the option Stop between pages. Then at the end of the scanning process current page A dialog box will appear asking you whether to continue the scanning process. Click on the Yes button to scan the next page or No- to complete the scanning process.

Scanner TWAIN driver interface

From the menu File select team Scan multiple pages. To start the scanning process in the scanner's TWAIN dialog box, simply click on the button Scan(the name of the button depends on the specific implementation of the TWAIN driver of your scanner) and to continue the scanning process, click on the button Scan in the twain dialog of the scanner.

To complete the scanning process in the Twain dialog of the scanner, simply click on the button Close(or something similar in meaning).

Advice: In order for you to control the results of the scanning process, on the tab Scan/Open(access: Service to Options) activate the option Open images as the scanning progresses. In this case, the scanned image will appear in the dialog box Image. If the image is scanned incorrectly, stop scanning (from the menu File select team Stop scanning) and rescan the image.

Opening image files

In the ABBYY FineReader OCR system, if you do not have a scanning device at all, you have the ability to recognize graphic files, which contain text information.

How to open an image

Click the arrow to the right of the button 1-Scan and from the drop-down menu select the command Open image. In the dialog box Open select images. All of them will appear in the program package, and the last of the selected images will open in the dialog box Image and in the dialog box Close-up, this will automatically place a copy of the image in the package folder.

Advice: If you want open images to be immediately recognized, use the Open and recognize. To do this from the menu Process select team Open and recognize(keyboard equivalent: Ctrl + Shift + D) and in the dialog box that opens Open select images for further recognition.

How to add images with double pages to a package

In an omnifont recognition system ABBYY texts In FineReader, when scanning books, it is more convenient to scan two pages (a book spread) at once.

In addition, to improve the quality of recognition, such images should be divided into two so that each page corresponds separate page package, since analysis and final result recognition in the program is carried out for each page separately.

To add double pages on a bookmark to a package Scan/Open(access: Service to Options) activate the option Divide a book spread.

How to check and correct the resulting image

The recognized image may be heavily cluttered. This means that it may contain many extra points of the middle or Bad quality, which may negatively affect the quality of the recognized text. In order to reduce the number of extra points, you can use the option Clear away debris. To do this, simply from the menu Image select team Clear image from garbage. If you want to clear a separate block (a section of the image highlighted in a frame) from “garbage”, then from the menu Image select team Clear the block of debris.

Important: If the source text was very light or the source text used a very thin font, then using the function Clear image may cause periods, commas, or thin elements letters, which degrades the quality of recognition.

Important: If you scan or open “junk” images, then before placing such images in the program package, please refer to the section Image processing, which is on the bookmark Scan/Open(access: Service to Options) activate the option Clear the image of debris.

How to invert an image

Some scanners convert black to white and white to black. To get the standard presentation of the document (black font on a white background from the menu Image select team Invert.

Important: If you open inverted images, then before adding such images to the program package in the section Image processing on the bookmark Scan/Open(access: Service to Options) be sure to activate the option Invert.

How to rotate or flip an image

During the recognition process, the image must have a standard orientation: the text must be read from top to bottom, and the lines must be horizontal. By default, the program detects and corrects the image orientation automatically during recognition.

If the image orientation was determined incorrectly, then on the Scanning/Opening tab, deactivate the option Determine page orientation(during recognition process) and rotate the image manually.

How to rotate an image 90 degrees to the right - select from menu Image team Rotate clockwise 90 degrees left - select from menu Image team Turn counterclockwise. 180 degrees - select from menu Image team Rotate 180 degrees.

You can reflect the image relative to: a horizontal line - select from the menu Image team Mirror reflection relative to the horizontal. vertical line - select from the menu Image team Mirror reflection relative to the vertical.

How to remove a portion of an image

If you want to exclude some part of the text from recognition or you have large areas of garbage in the image, then you have the opportunity to erase it. For this:

Select a tool (from the toolbar in the dialog box Image) and by clicking on left button mouse, select the area of ​​the image that you want to delete. Release the button, the selected part of the image will be deleted.

How to resize an image

On the panel Image(in the dialog box Image) select the tool and left-click on the image. Image will increase/decrease by half.

Click right click mouse over the image and select the command from the menu Scale and the scale you need.

How to get information about an image

You have the opportunity to obtain the following information about open image: width and height of the image in pixels; vertical and horizontal resolution in dots per inch (dpi); image type.

Right-click on the image and select command from the menu Properties. In the dialog box that opens, select the bookmark Image.

Undo last action

To cancel last action on the panel Standard just click on the button Cancel.

Important: For re-execution last undone action on the panel Standard just click on the button Return.

Page numbering when adding to a package

By default, each scanned page is assigned a number one greater than the number of the last image in the batch.

You can also specify the page number to be added manually (for example, you need to keep the original page numbering or you are scanning a stack of pages sorted in order). To do this, activate the option Request page number when added to a package on a bookmark Scan/Open(access: Service to Options).

In the dialog box Page number specify the page number from which scanning begins and select the option In one in field Pagination. Select the page numbering method: ascending or descending. Whether the stack is ascending or descending depends, for example, on how you place the stack in the ADF—whether the smaller or larger numbers are on top.

Reduce color/gray image resolution to 100 dpi

This option is used when adding large color images to the package. In this case, firstly, the package will take up less disk space, and secondly, the process of processing a group of pages will be faster.

Important: This option does not affect the quality of text recognition. This reduction in resolution affects the quality of saved images: the resolution of the images is reduced to 100 dpi.

How to convert a color/gray image to black and white

Check this option when scanning through the scanner's TWAIN dialog in gray mode (with automatic brightness adjustment) or when scanning in color, if the scanned documents do not contain color images, color font and background, or you do not need to transfer color to the output image. In this case, the images saved in the package will take up less disk space.

How to analyze page layout

Before starting recognition, the program must know which areas of the image need to be recognized. To do this, an analysis of the page layout is carried out, during which blocks with text, pictures, tables and barcodes (for the Office version) are highlighted.

Page layout analysis can be done either automatically or manually. In most cases, FineReader itself successfully copes with the analysis complex pages. Automatic analysis is performed using the button 2-Recognize simultaneously with text recognition.

Important: A separate page layout analysis procedure is also available (access: Process to Page Layout Analysis). True, the quality of segmentation may be lower, since the joint recognition and segmentation procedure uses Additional Information, obtained during the recognition process.
