Pixma MX490 Keeps Cycling

[elstx61]

Canon Pixma MX490 powers on and goes through initialization, then powers back off.  Keeps repeating the process as long as it's plugged in.  Buttons are non-responsive.

I have MS Windows 10 and the S Mode does not allow me to download the firmware update without turning off the S Mode which I do not want to do.  Which is the appropriate MS Windows App to allow me to do the firmware update download?

I share your opinion.  The error was pushed out - the fix should be pushed out as well.

To reconnect to wifi, did you also change the printer IP/DNS number? That step corrected my problem. 

[SamS1]

you need to disconnect the printer from the internet (shut down your router), unplug/plug the printer back in, and apply the fix.

'S mode'???  Never heard of that. Could you elaborate?

I can't complete the firmware update because my printer keeps rebooting in the middle of it.  What can I do now?

[graumli]

Disconnect your wifi (router). Use an USB cable to connect your printer with your computer. Once complete, reboot your wifi and your printer should able to find wifi and stay operational.

Yep, this.  Worked like a charm once I disconnected it from Wi-Fi.

I just completed the firmware update, and it's working like normal again.

I tried the solution you suggested and my MX492 continues to power cycle. It is connected wirelessly to my computer.
