Scanning an Image from an Application

You can scan an image from a TWAIN or WIA-compliant application and use the image in that application. The procedure to follow varies depending on the application. The following is only one example. For a detailed procedure, refer to the documentation for the application you are using.

1. Place the document face-down on the platen glass.
   
   
   
   
2. In the application, select the command to scan a document ([Import], [Acquire image], etc.).
   
   
3. Select the scanner driver.
   
4. 1. To use ScanGear MP, select 'Canon MPxxx' (where xxx indicates your machine name).
      
   2. To use the WIA driver (in Windows XP only), select 'WIA-Canon MPxxx' (where xxx indicates your printer's model). (Advanced Mode options are not available using the WIA driver.
      
      Note: To scan with the value previously set in [Adjust the quality of the scanned picture], select 'Custom Settings'.
      
      
5. In ScanGear MP dialog box, click 'Advanced Mode' tab to set detailed settings.
   
   
   
   
6. Preview the scan and make adjustments as required.
   
   
7. Click 'Scan'. When scanning is completed, the scanned image will appear in the application.
