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.

“Regular Maintenance” on p. 84.)
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.
