✘Scanning Results Are Not as Expected
If there is a problem with the scanning result (e.g., 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 not set to an appropriate value. |
Solution | If the image is dark, set a higher [Brightness] setting, or if the image is faint, set a |
| lower [Brightness] setting. |
