Cannot Detect the Printer during Wireless LAN Setup: Check 2
Does the firewall function of your security software or operating system for
a computer interfere with setting up the network communication?
The firewall function of your security software or operating system for a computer may limit
communications between the printer and your computer. Confirm the setting of firewall function of your
security software or operating system or the message appearing on your computer.
If the firewall function interferes with setting up:
• When the message appears on your computer:
If the message warning that Canon software is attempting to access the network appears on the
computer, set the security software to allow access.
• When the message does not appear on your computer:
Cancel to set up, then set the security software to allow Canon software* to access the network.
* Set the security software to allow Setup.app, Canon IJ Network Tool.app,
canonijnetwork.bundle, CIJScannerRegister.app, Canon IJ Scan Utility2.app, and
CIJSUAgent.app to access the network.
After setting the security software, try to set up the network communication from the beginning.
• For the operating system firewall settings or the security software firewall settings, refer to the
instruction manual of the computer or software, or contact its manufacturer.
If there is no problem with the firewall settings:
