⋅Scanning Results Are Not as Expected
If there is a problem with the scanning result (for example, the scanned image is not clear, or the image is striped or dirty) the probable causes are incorrect ISIS/ TWAIN driver settings or a problem with the scanning unit inside the scanner.
Scanning results can also become skewed if the ISIS/TWAIN driver has not been installed correctly, or the application in use does not support ISIS/TWAIN driver functions.
Symptoms | The scanned image is too dark (or faint). |
Problem | The Brightness setting is set incorrectly. |
Solution | If the image is dark, click the [Brightness] tab in the Properties for |
| Canon |
| right to increase the Brightness setting, or if the image is faint, drag |
| the <Brightness> slider to the left to decrease the Brightness setting. |
Symptoms | Text or images on the rear side of your document appear in the |
| scanned image. |
Problem | The Brightness setting is too low, or the paper is too thin. |
Solution | Click the [Brightness] tab in the Properties for Canon |
| dialog box → drag the <Brightness> slider to the right to increase |
| the Brightness setting. If the paper is too thin, make a copy of the |
| documents and then scan the copy. Alternatively, click the [Image |
| processing] tab in the Properties for Canon |
| select the [Prevent Bleed Through / Remove Background] check |
| box. |
