Hi burninmedia,
The firmware update of the PIXMA iP8720 is not available on the web site as a download, as it is performed using the printer's remote user interface.
Your PIXMA iP8720 must be connected to your network. Once connected, print the network configuration page to determine the printer's IP address. To print this page, please load plain paper in the printer and press and hold the RESUME / CANCEL button until the POWER lamp flashes white 6 times, then let it go.
On the page that printed, please take note of the IPv4 IP Address.
On your computer, please open a web browser and enter the printer's IPv4 IP Address in the address bar to access the iP8720's remote user interface.
Once that page loads, click on Firmware Update in the menu on the left side to perform the update.
Confirm the update message by clicking Yes and the update will be performed.
I performed this update today, so I know that the update is available and working correctly.
Please note, once the update is complete, the IPv3 IP address of the printer may change.
