Problem

The rollers inside the scanner are dirty or worn.

Solution

Clean the rollers (See p.63.). If the rollers are worn, then they need

 

to be replaced. Contact your local authorized Canon dealer or service

 

representative to purchase a roller replacement kit.

For information on removing jammed documents, see "Clearing a Paper Jam," on p. 33.

⋅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.
