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 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 4 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. For details on roller cleaning and replacement procedures, refer
to the User Manual.
(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.
