Chapter 3 Appendix × 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 Problem Solution The scanned image is too dark (or faint). The Brightness setting is set incorrectly. If the image is dark, click the [Brightness] tab in the Properties for Canon DR-3010C dialog box → drag the slider to the right to increase the Brightness setting, or if the image is faint, drag the slider to the left to decrease the Brightness setting. Symptoms Problem Solution Text or images on the rear side of your document appear in the scanned image. The Brightness setting is too low, or the paper is too thin. Click the [Brightness] tab in the Properties for Canon DR-3010C dialog box → drag the 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 DR-3010C dialog box → select the [Prevent Bleed Through / Remove Background] check box. Symptoms Problem Solution Double-sided scanning is not possible. The Scanning Side drop-down list is set to 'Simplex'. Click the [Basic] tab in the Properties for Canon DR-3010C dialog box → select [Duplex] from the Scanning Side drop-down list. Symptoms Problem Solution The scanned image is skewed. The document has been fed at an angle (skew). Use the document guide adapter to prevent document skew.

The scanning glass or rollers inside the scanner are dirty. Clean the scanning glass and rollers. If lines still appear on the image even after cleaning the scanning glass and rollers, the scanning glass inside the scanner may be scratched. Contact your local authorized Canon dealer or service representative. Symptoms Problem Solution There are abnormalities in the image. The scanning glass or rollers inside the scanner may be dirty. Clean the scanning glass and rollers. If there are still abnormalities in the image even after cleaning the scanning glass and rollers, the scanning glass inside the scanner may be scratched.

Problem The scanning glass or rollers inside the scanner may be dirty. Solution Clean the scanning glass and rollers. If the auto-detection of the 3 paper size fails even after cleaning the scanning glass and rollers, the scanning glass inside the scanner may be scratched. Contact your local authorized Canon dealer or service representative. Symptoms Problem Solution The scanned image is abnormal in some applications. A function not supported by the application was used. Some applications do not support functions, such as auto-detection of the paper size. Scanning documents with an application such as this will result in an abnormal scanned image. Try scanning without setting auto-detection of the paper size. - 38 -
