Troubleshooting
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.
Problem 1 The scanner does not turn ON.
Solutions (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.
Problem 2 The scanner is not recognized.
Solutions (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 “Problem 1” 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.
(6) When the Auto Start switch on the scanner is set
to ON, you can only scan with the built-in
application, CaptureOnTouch Lite. In this case,
scanning from applications on the computer is
disabled.
(7) When the scanner is operated with Windows and
if “?”, “!”, or “x” icons appear for the scanner in
Device Manager, delete the scanner in Device
Manager and reinstall the scanner driver.
Problem 3 Documents feed askew (scanned images are
slanted).
Solutions (1) Align the document guides to fit the documents as
closely as possible, and load the documents so
that they feed straightly.
(2) Enable [Automatically straightens skewed images]
(or [Deskew]) in the scanner driver settings.
(3) If many pages have been scanned since the last
roller cleaning, clean the rollers and separation
pad. If documents still feed askew, roller
replacement or other maintenance may be
needed. (See p. 98.)
(4) Confirm that the separation pad is attached
securely.
(5) Perfectly straight scanning may not be possible for
the document due to the structural design of the
scanner.
Problem 4 CaptureOnTouch Lite does not start.
Solutions (1) If the Auto Start switch on the scanner is set to
OFF, the built-in application, CaptureOnTouch
Lite, does not start. Close the feed tray to turn OFF
the scanner, and set the Auto Start switch to ON.
(2) If access to USB devices is blocked by security
software, you may not be able to use
CaptureOnTouch Lite.
Problem 5 The auto play screen appears when the scanner is
connected, but you cannot scan with
CaptureOnTouch.
Solutions When the Auto Start switch on the scanner is set to
ON, you can only scan with the built-in application,
CaptureOnTouch Lite. Close the feed tray to turn OFF
the scanner, and set the Auto Start switch to OFF.
