Use CanoScan Toolbox to Create a PDF

1. Launch CanoScan Toolbox, and select 'PDF'.
   
2. Specify 'Adobe Acrobat Professional' in Select Application.
   
3. Change the Scan Settings setting depending on the data.
   
   Note: When using OCR, a high resolution of 300 dpi or more is recommended.
   
4. When scanning the next data, click 'Next'. When scanning all the data is completed, click 'Finish'. The PDF file window will be displayed in Acrobat.

Another alternative method would be to use non-Acrobat application to scan and save the image. Then, use Acrobat to convert the saved file to a PDF file.
