Disable block in firewall function temporarily.
The firewall of your security software or operation system for computer may limit communication between
the machine and your computer. Check the firewall setting of your security software or operation system
or the message shown on your computer and disable block temporarily.
If firewall interferes with setup:
• If message appears:
If a message appears warning that Canon software is attempting to access the network, set the
security software to allow access.
After allowing the software to access, click Redetect on the Check Printer Settings screen to
redetect the machine.
If the machine is found, follow the instructions on the screen to continue to set up network
communication.
• If no message appears:
Cancel the setup, and then set the security software to allow Canon software to access the network.
◦ For Windows:
The file Setup.exe or Setup64.exe in the win > Driver > DrvSetup folder on the Setup CD-ROM
◦ For Mac OS:
Setup.app, Canon IJ Network Tool.app, canonijnetwork.bundle, CIJScannerRegister.app,
Canon IJ Scan Utility2.app, and CIJSUAgent.app
After setting the security software, redo the network communication setup from the beginning.
After setup is completed, enable firewall.
