Canon U.S.A., Inc. has recently become aware of a situation where select Canon inkjet printers continuously reboot or power down after the Canon logo appears if the product is connected to the internet. If this occurs, the printer cannot be used.
When a printer is powered on and connected to the Internet, it will access an external server. Beginning on May 30, 2022, an update in information sent from the external server to the affected printer models resulted in an error that caused it to go through a continuous reboot or power down.
On June 7, 2022, the matter was resolved.
Note: If the printer continues to reboot, turn it off or unplug the power cord from the printer. Wait up to ten seconds, and then power on the printer.
▆ Recommended Action
Although the matter is resolved, we recommend that the affected printer models’ firmware be updated to help prevent risk of reoccurrence.
Below are options to update the firmware on the affected printer models.
On nearly all the affected printer models listed below, the firmware can be updated from the printer’s operational panel while it is connected to the Internet. The printer’s display will typically indicate when a firmware is available for updating via the operational panel.
See the table below to confirm if this option is supported by your printer. If supported, click "Yes" under Option One for your printer model in the table below. This will take you to Canon’s knowledgebase article for detailed instructions on updating the firmware.
For printer models whose firmware cannot be updated via the operational panel, the Remote User Interface (also referred to as Remote UI) can be used for this purpose.
See the table below to confirm if this option is supported by your printer. If supported, click "Yes" under Option Two for your printer model in the table below. This will take you to Canon’s knowledgebase article for detailed instructions on updating the firmware.
Alternatively, the firmware for each of the affected printer models can be updated immediately using an updater that is currently available on Canon’s website. To use the updater, see the requirements listed below. Please click "Yes" under Option Three for your printer model in the table below. If the website does not automatically detect the computer’s operating system, select it from the Operating System drop-down.
v Requirements for Option Three:
Affected printer models and link to its respective firmware update procedure:
(Update Firmware from Operation Panel)

ok, I did the firmware update on my MB2320, but now it shows all the color ink is empty! They were new cartridges! So is this suppose to happen with the firmware update? Seems to be working ok, otherwise, but I really don't want to buy new ink!
We checked the link for the PIXMA MG7520 and we were immediately presented with Mac and Windows versions of the firmware update. If it continues not to work, try visiting the page through a different browser.
I have an MG7520, and when I go to the link above, it appears there is no firmware update available for Windows 10. Am I missing something?
A FW update is available for this model.

If you power down your printer, then use your mac to get to Canon site and download 1) new driver 2) new firmware 3) new security patch and 4) new software created to setup your printer without a cable but over your wireless. I must recommend that you get into your internet router and turn off port 80 in both directions to and from your printer's IP. Otherwise you have to have the old printer cable. Then install everything you downloaded once the printer is back on your network (but not on the internet). Hope this helps.
I’m glad I googled this issue before buying a new printer! The instructions in the update do not instruct you to disconnect from the internet. I needed to turn off my router as that was the only way to accomplish that requirement.
Next, I’m going to find out how to stop automatic updates. This was a lot of effort to fix a printer that was otherwise working quite satisfactorily.
