Symptoms	A TIFF file saved in CapturePerfect 3.0 cannot be opened by other
	applications.

	file again in CapturePerfect 3.0.

⋅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 DR-3010C dialog box → drag the <Brightness> slider to the
	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 DR-3010C
	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 DR-3010C dialog box →
	select the [Prevent Bleed Through / Remove Background] check
	box.

Symptoms	Double-sided scanning is not possible.
Problem	The Scanning Side drop-down list is set to ’Simplex’.
Solution	Click the [Basic] tab in the Properties for Canon DR-3010C dialog
	box → select [Duplex] from the Scanning Side drop-down list.

Symptoms	The scanned image is skewed.
Problem	The document has been fed at an angle (skew).
Solution	Use the document guide adapter to prevent document skew. Click
	the [Basic] tab in the Properties for Canon DR-3010C dialog box →
	select the [Deskew] check box.

Symptoms	Lines, smudges, or dirt appear on the scanned image.
Problem	The scanning glass or rollers inside the scanner are dirty.
Solution	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	There are abnormalities in the image.
Problem	The scanning glass or rollers inside the scanner may be dirty.
Solution	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. Contact your
	local authorized Canon dealer or service representative.
