Check that security software's firewall is off.
A message may appear warning you that Canon software is attempting to access the network. If this warning
message appears, set the security software to always allow access.
Quit the security software and make sure that the printer is recognized and ready to use. If so, the cause is
the firewall setting. Change the firewall settings so that the printer is recognized and ready to use. For details,
contact the manufacturer of the security software.
If you are using any programs that switch between network environments, check their settings. Some programs
use a firewall by default.

want to connect to, and then setup manually.
