Scanned Images Are Not Correct
If the scanned images are not clear, if there are lines or spots on the images, or if there is some other problem with scanned images, the likely causes are listed below. Check each item and take the appropriate action.
Cause | The sensor glass or the rollers inside the scanner are dirty. |
Remedy | Clean the sensor glass and rollers. (For instructions on cleaning |
| the sensor glass and rollers, see “Cleaning the Sensor Glass and |
| the Rollers,” on p. 46.) |
|
|
Cause | The scanner’s internal sensor glass is scratched. |
Remedy | Contact your local authorized Canon dealer or service |
| representative. |
|
|
Cause | The application software is not set up properly for |
| scanning. |
Remedy | Check the scanning settings of the scanning utility. |
| For example, if the scanned image is blank, the brightness setting |
| may be too high. If the resulting scanned images are too dark, the |
| brightness setting may be too low. |
|
|
Cause | The scanner driver or application software is not running |
| normally. |
Remedy | If the software is set properly for scanning and scanning is still |
| not possible, the scanner driver or the application software may |
| not be running normally. Reinstall the scanner driver or the |
| application software. (For details on how to install the scanner |
| driver, see “Installing the Scanning Utility,” on p. 17. For details |
| on how to install the application software, refer to the application |
| software instruction manual.) |
|
|
Cause | Attempting to use a function of the |
| supported by the application software. |
Remedy | Some application software may not support certain functions, |
| such as automatically detecting the paper size or changing the |
| scanning mode/resolution through the scan panel. Using such |
| application software for scanning may yield abnormal scanning |
| results. Try scanning without using functions such as automatic |
| paper size detection or margin settings. |

If problems with the scanned images persist even after trying these solutions, contact your local authorized Canon dealer or service representative.
