Service Notice: UPDATE: Canon Inkjet Printer continuous reboot loop or powering down

[TeamPrinter]

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.

▆ Update

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.

•  Option One (Recommended)

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.

• Option Two

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.

• Option Three

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:

• USB cable
• Printer’s driver installed on the computer in which the firmware update will be performed

Affected printer models and link to its respective firmware update procedure:

Model	Option One (Update Firmware from Operation Panel)	Option Two (Update Firmware using Remote UI)	Option Three (Update Firmware using Updater)
PIXMA iP110	-	Yes	Yes
MAXIFY iB4020	Yes	Yes	Yes
MAXIFY MB2020	Yes	Yes	Yes
MAXIFY MB2320	Yes	Yes	Yes

MAXIFY MB5320	Yes	Yes	Yes
PIXMA MG6620	Yes	Yes	Yes

Agreed. i'm a retired tech and it took a while to get the procedure to work as presented by Canon. I can see the "average" user having a difficult time with it.

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!

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?

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.

[mhmcpa732]

Thank you.  It does appear that it was a browser issue.  I was able to get the firmware update and it is working now.

I only have a Mac computer and do not have a cord to connect directly to my computer. Is there a way to fix this issue without connecting directly to a computer? I have a MX492 printer. 

[kmhart]

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.

Just so you know….problem was not caused by a firmware update….I don’t use automatic updates and have confirmed that nothing on my printer ever changed…..canon has still not told us what they did that caused the problem -but it was not a software or firmware download…..
