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 will not turn on. Solutions (1) Confirm that the power cord is properly connected. (2) Confirm that the power plug is plugged into a power outlet. Problem 2 The scanner is not recognized. Solutions When connecting via USB: (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) USB connection is not recognized when connected via LAN. Disconnect the LAN cable, restart the computer, and reconnect the USB cable. Problem 3 Solutions When connecting via wired LAN: (1) Check the LAN cable connection. (2) The specified IP address may already be in use by another device. Contact your network's system administrator to change the IP address. (3) The specified device name may already be in use by another device. Contact your network's system administrator to change the device name.

Disconnect the USB cable, restart the computer, and reconnect the LAN cable. Documents feed askew (scanned images are slanted). (1) Align the document guides to fit the documents as closely as possible, and load the documents so that they feed straightly. (2) Open the Document Feeder Tray Extension and load the documents. (3) Enable [Automatically straightens skewed] in the scanner driver settings. (4) If many pages have been scanned since roller cleaning, clean the rollers. If documents still feed askew, roller replacement or other maintenance may be needed. See "Maintenance" on p. 105 for roller replacement procedures. 129
