Resulting Scanned Images Are Not Correct

If the resulting scanned images are not crisp, if there are lines or spots on the images, or if there is some other problem with scanned images, 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 as described on p. 54.

 

 

Cause

The scanner’s internal platen 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 related settings, such as brightness in the

 

application software.

 

For example, if the document cannot be scanned at all, it is

 

possible that the brightness setting is too high. If the resulting

 

scanned images are too dark, it is possible that the brightness

 

setting is 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, it is possible that the scanner driver or the

 

application software is not running normally. Reinstall the

 

scanning driver or the application software. For details on how to

 

install the scanner driver, see “Installing the ISIS/TWAIN

 

Driver,” on p. 27. For details on how to install the application

 

software, refer to the application software instruction manual.

 

 

Cause

Attempting to use a function of the DR-2050C that is not

 

supported by the application software.

Remedy

Certain application software may not support auto page size

 

detection or other functions. You may experience abnormal

 

scanning results when scanning with such an application. If this

 

happens, try scanning again after turning off auto paper size

 

detection, etc.

 

 

If you continue to have problems with the scanned image after trying the above countermeasures, try using the following procedure to adjust the scanner.
