The firewall function of your security software or operation system for computer may limit communications between the machine and your computer. Confirm the setting of firewall function of your security software or operation system or the message appearing on your computer.
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, and CNNSelectorAgent.app to access the network.
After setting the security software, try to set up the network communication from the beginning.
For the operation system firewall settings or the security software firewall settings, refer to the instruction manual of the computer or software, or contact its manufacturer.
