Welcome to The Canon Forums, and thank you for your inquiry!


We appreciate your participation, however, we need to let you know that the Canon Forum is hosted and moderated within the United States by Canon USA. We are only able to provide support for Canon products manufactured for and used within the US market.


If you live outside the United States, to go: and select your country or region for your support needs.

Hi, scanner solution is easy as there is other software managing this, only the printer itself, is software of the MG5420 or MG5500 not solving the problem?


That is what can happen when a new operating system is installed.


It is very important to check that all critical hardware devices associated with the computer will be supported, or else do a cost/benefit study to see if the benefits from the new OS are worth the cost of upgrading components.


Looks like your printer has been arond for a while.

I have the same issue. Purchased a new imac that came pre-installed with  Big Sur and now I can't print from my Pixma ix6820. I can't get through to Canon...and reading these messages sounds like I have to buy a new printer?!  Yes, my Pixma is a 2017 (gasp, four years old!!), but it is in fine shape and I've already purchased ink for it. I'm so sick of the disposable culture we live in. I will be purchasing an Epson or another brand. NOT canon.

Same response when I tried to find drivers for my MX340. I refuse to buy a new Canon printer to fix my problem. I have an old brother laser jet printer that works with my new mac. Canon just lost a customer.
