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)
