× Saved Image Files Do Not Open
When image files saved by CapturePerfect 3.0 cannot be opened by other
applications, the probable causes are as follows.
Symptoms A multi-page TIFF file saved in CapturePerfect 3.0 cannot be
opened by other applications.
Problem The application you are using to open the TIFF file does not support
multi-page TIFF files.
Solution Open the file with an application that supports multi-page TIFF files.
Symptoms A TIFF file saved in CapturePerfect 3.0 cannot be opened by other
applications.
Problem If the TIFF file saved in CapturePerfect 3.0 has been compressed, the
application you are using to open the TIFF file does not support the
compression type that was used to save the file in CapturePerfect 3.0.
Solution Set the compression type for the image file to [None] and save the
file again in CapturePerfect 3.0.
× 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 set incorrectly.
Solution If the image is dark, set a higher [Brightness] setting, or if the image
is faint, set a lower [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 Set a higher [Brightness] setting. If the paper is too thin, make a
copy of the documents and then scan the copy. Alternatively, enable
the [Prevent Bleed Through / Remove Background] setting.
Symptoms Double-sided scanning is not possible.
Problem [Scanning Side] is set to [Simplex].
Solution Set [Scanning Side] to [Duplex].
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, and
select the [Deskew] check box in the Basic tab of the ISIS/TWAIN
driver properties dialog box (See p.43.).
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 The scanned image is abnormal in some applications.
Problem A function not supported by the application was used.
Solution 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.
