A fax cannot be sent or received on an optical fiber line.   

The machine is compliant with use on analog lines. When using an optical fiber line or IP phone line, the machine may not work correctly depending on the connection environment or connected devices. In such a case, contact the provider of the optical fiber line or IP phone.

You are unsure of the SSID or the network key of the wireless router to be connected. The SSID is not displayed on the screen.   

Check whether the SSID can be found on the wireless router or package box.
Check the SSID or the network key of the wireless router by using Canon MF/LBP Wireless Setup Assistant.
Checking the SSID and Network Key

The SSID of the wireless router to be connected is not displayed in the access point list.  

Check whether the SSID is correct.
Checking the SSID and Network Key
If the SSID of the wireless router is hidden (using a stealth mode*), set the SSID to be visible on the wireless router.
 
A mode that disables the SSID auto-detection of other devices.
Check whether the machine is properly installed and ready to connect to the network.
When the machine cannot connect to the wireless LAN

The machine dials up to an unintended connection destination (if a dialup router is connected to a network).   

If a dialup router does not need to pass broadcast packets, set the dialup router so that the broadcast packets will not pass. If the dialup router needs to pass broadcast packets, check whether the settings are correct.
If a DNS server is located in an external network, set the IP address to be connected, not the host name, even if connecting to the devices that are on the network that is connected to the machine.
If a DNS server is located on a network that is connected to the machine and the information about the devices that are connected to an external network is registered to the DNS server, check whether the settings are correct.

The PC cannot correctly recognize the machine.   

When using the machine with a USB connection, be sure to match the machine settings to the OS of the PC.

Check the status of your computer.
Have the settings of the computer and the wireless router been completed?
Are the cables of the wireless router (including the power cord and LAN cable) correctly plugged in?
Is the wireless router turned on?
If the problem persists even after checking the above:
Turn off the devices, and then turn them on again.
Wait for a while, and try again to connect to the network.
 
 
Check whether the machine is turned ON.
If the machine is turned ON, turn it OFF, and then turn it back ON.
 
 
Check the installation site of the machine and the wireless router.
Is the machine too far from the wireless router?
Are there any obstacles such as walls between the machine and the wireless router?
Are there any appliances such as microwave ovens or digital cordless phones that emit radio waves near the machine?
 
 
Perform one of the following settings again.
When you need to manually set up the connection
If the wireless router is set as described below, manually enter all the required information for the wireless LAN connection (Setting Up Connection by Specifying Detailed Settings).

The WEP key that was automatically generated (hexadecimal) is selected.
 
A function in which the wireless router refuses the connection if the SSID on the device to be connected is set to "ANY" or is blank.
When you need to change the settings of the wireless router
If the wireless router is set as described below, change the settings of the router.
The MAC address packet filtering is set.
When only IEEE 802.11n is used for the wireless communication, WEP is selected or the WPA/WPA2 encryption method is set to TKIP.
