Converting scanned pages to Adobe PDF
You can use the Create PDF From Scanner command to run your scanner. Before you
begin scanning, make sure that your scanner is installed and working correctly. Follow the
scanner instructions and test procedures to ensure proper setup. (See
TWAIN scanner drivers, which are industry-standard drivers compatible with almost all
desktop scanners, are supported, together with Windows Image Acquisition (WIA) drivers
on Windows XP.
Note: Adobe PDF documents created from scanned pages are compatible with Acrobat
5.0 and later. For compatibility with Acrobat 4.0, use a compression method other than
JBIG2.
To create Adobe PDF files from scanned pages:
1. In Acrobat, choose File > Create PDF > From Scanner, or choose From Scanner from the
Create Adobe PDF menu
You can apply OCR and add tags for accessibility while scanning paper documents.
2. In the Create PDF From Scanner dialog box, select your scanning device.
3. Choose Front Sides or Both Sides format. (The scanner's settings might overwrite these
settings in Acrobat. For example, if you select Both Sides in Acrobat and Single Side in
the scanner, only one side scans.)
4. Specify whether to create a new PDF document or append the converted scan to the
currently open PDF document. If no PDF document is open, the Destination menu is
unavailable, and the converted scan becomes a new document.
5. Select Recognize Text Using OCR if you want to apply OCR and font and page
recognition to the text images and convert them to normal text. Click Settings, and specify
options.
Primary OCR Language specifies the language for the OCR engine to use to identify the
characters. In the Japanese version of Acrobat, the roman languages are available only if
you perform a Custom installation and select Roman Language Support. In non-Japanese
versions of Acrobat, the Japanese language is available only if you perform a Custom
installation and select Asian Language Support.
PDF Output Style allows you to specify either Searchable Image or Formatted Text &
Graphics. Choose Searchable Image to have a bitmap image of the pages in the
foreground and the scanned text on an invisible layer beneath. The appearance of the page
does not change, but the text becomes selectable and readable. Choose Formatted Text &
Graphics to reconstruct the original page using recognized text, fonts, pictures, and other
graphic elements.
Downsample Images decreases the number of pixels in color, grayscale, and monochrome
images. Downsampling of scanned images is performed after OCR is complete.
6. Select Add Tags To Document (Improves Accessibility For Disabled Users) if you want
Acrobat to analyze how the page is laid out, which defines the reading order. This option
is available only if you select Recognize Text Using OCR. To correct reading order
problems, see
7. Click Image Settings to set compression and filtering options. (See
options.)
8. Click Scan.
9. Set additional scanning options for your scanner, and finish scanning. Click Next if you
are scanning multiple pages; click Done when you finish. (The scanning operation and
options available vary with the type of scanner.)
Note: If you try to select text in a scanned PDF file that does not have OCR applied,
Acrobat asks if you want to run OCR. If you click OK, the Recognize Text dialog box
opens. (See
on the toolbar.
