Common Problems and Solutions
This section provides recommended solutions to common problems.
If you have a problem that is not solved by the following, contact your local
authorized Canon dealer.
Q1 The scanner does not turn ON.
A1 1 The scanner remains OFF while the feed tray is closed.
When you open the feed tray, the scanner turns ON
automatically.
2 If the scanner is connected to the computer via a USB hub,
try removing the hub and connecting directly to the
computer.
Q2 The scanner is not recognized.
A2 1 Confirm that the scanner is properly connected to the
computer with a USB cable.
2 Confirm that the scanner is turned on. See the previous "Q1"
"The scanner does not turn ON.". if the scanner does not
turn on.
3 The computer's USB interface may not support the scanner.
The scanner cannot be guaranteed to work with all USB
interfaces.
4 Confirm that the supplied USB cable is used to connect the
scanner to the computer. The scanner cannot be guaranteed
to work with all available USB cables.
5 If the scanner is connected to the computer via a USB hub,
try removing the hub and connecting directly to the
computer.
Q3 Documents feed askew (scanned images are slanted).
A3 1 Reduce the number of pages that you load into the scanner
at one time, and then scan again.
2 Align the document guides to fit the documents as closely as
possible, and load the documents so that they feed straightly.
3 Set [Automatically straightens skewed images] to other than
[OFF] in the scan mode settings.
4 If many pages have been scanned since the last roller
cleaning, clean the rollers and separation pad. When
cleaning the scanner refer to "Cleaning the Scanning Glass
and the Rollers" on p.56. When replacing, refer to
"Replacing Consumable Parts" on p.57.
5 Confirm that the separation pad is attached securely.
6 Perfectly straight scanning may not be possible for the
document due to the structural design of the scanner.
Q4 CaptureOnTouch Lite does not start.
A4 If access to USB devices is blocked by security software, you
may not be able to use CaptureOnTouch Lite.
Q5 If white lines or streaks appear in scanned images.
A5 Clean both sides of the scanner glass, and the rollers. If a sticky
substance such as glue or correction fluid is found, carefully wipe
with just enough pressure to clean the area where the lines
appear. For cleaning the scanner, refer to "Chapter 7 Regular
Maintenance". If the problem cannot be solved by cleaning, the
internal glass may be scratched. Contact your local authorized
Canon dealer.
Q6 Pages are missing.
A6 Then [Scanning Side] setting in the advanced settings dialog box
is [Skip blank page], documents with very little black may be
unintentionally skipped. Decrease the [Set the likelihood of
skipping blank page] value "When you want to delete the images
of the blank pages in two-sided documents" on p.43, or select
another scan mode setting such as [Simplex] or [Duplex]. If
pages are skipped due to the document double feeding, see "Q7"
"Documents jam (or double-feed).".
