Chapter 6 Practical Examples

Problem

Text or images from the back side of your

 

document appear in the scanned image.

Cause

Brightness may be set too low.

Solution

Increase the Brightness setting. Or, enable the

 

[Prevent Bleed Through/Remove

 

Background] setting.

Cause

The paper is too thin.

Solution

Photocopy the document, and scan the copy.

 

 

Problem

Double-sided scanning is not possible.

Cause

Scanning Side is set to [Simplex].

Solution

Set Scanning Side to [Duplex].

 

If the Scanning Side is set to [Skip Blank

 

Page], images of blank pages are not saved.

 

 

Problem

A black margin appears around the

 

scanned document.

Cause

A document smaller than the preset paper

 

size has been scanned. Or, the loaded

 

document has shifted out of position.

Solution

Choose one of the following:

 

(1) Set [Page size] to [Auto-detection].

 

(2) Select the [White] background.

 

(3) Enable Border Removal if you want to use

 

the [Black] background setting.

 

 

Problem

The scanned image is skewed.

Cause

The document has been fed at an angle.

 

(skew)

Solution

Slide the document guides to match the width

 

of your document.

 

 

Problem

Lines, smudges, or dirt appear on the

 

scanned image.

Cause

The scanning glass or rollers inside the

 

scanner are dirty.

Solution

Clean the scanning glass and rollers. (See

 

“Regular Maintenance” on p. 5-2.)

 

If lines still appear on the image even after you

 

clean the scanning glass and rollers, the

 

scanning glass inside the scanner may be

 

scratched. Contact your local authorized

 

Canon dealer or service representative.

 

 

Problem

The scanned image is abnormal for

 

certain documents.

Cause

A detection function such as border

 

removal is enabled when scanning a

 

document that includes text or photos

 

extending to the edge of the page (the

 

scanner cannot accurately process the

 

edges of documents).

Solution

When a page has text or photos extending to its

 

edges, turn the detection functions off or scan

 

that page individually.

 

 

Problem

The scanned image is abnormal in some

 

applications.

Cause

A function not supported by the

 

application was used.

Solution

Some applications do not support functions

 

such as auto-detection of page size, so

 

scanning with such applications will produce

 

abnormal scanned images.

 

If abnormal image appearance seems to be

 

application-dependent, try scanning with auto-

 

detection disabled.
