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.

Lilmesz - that process will work.  Let me break it down a bit more clear.

If you are connected using wifi then it works as follows.
1.  Unplug your printer from the outlet (it'll now be powered off)

2.  Go to the modem in your house for your cable and internet.  Disconnect all of the cords and let it sit for a couple minutes.

3.  Go plus the printer back in and it'll start up without the cycling (problem isn't solved yet) which will allow you to then access the Menu on the printer.  Then go to Setup menu > Web service setup > DNS server setup > Manual setup. Configure an IP from your internal network that is not in use or another IP that is not a DNS server, as the printer will not be able to make queries. Choose a random IP number. I just made up a random one using this format192.158.1.38 (hell use that number if you want).  Once configured, press OK. Select the 'No' option and press OK. Wait a few moments to complete the configuration.

4.  Go and plug back in all the wires on your cable/internet modem.  Once that connection is restored the printer will work.

I'm not super tech savvy but was able to do it.

I have the same problem.  I have tried to read all of the comments.  I am embarrassed to say I don't know how to disconnect from wifi.....I am wireless.....to try the "unplug, remove from WiFi and restart" that some of you have said has some success.

Same here @KenShead!

Same thing happened to my MX492. Around Memorial Day 2022, I did notice before the weekend it was suggesting to download the latest firmware, which I didn't get around to doing. Now I can't get into settings to disable wifi if that is part of the power cycling problem. Tried unplugging. Can't communicate with my laptop. I may need to go buy an epson if Canon doesn't post the fix.

I am having the Exact same problem!

I tried the disconnect and press the button 10x’s and that did no help.

Please CANON fix this problem for ALL of us!!

With the cost of everything people can’t afyto just go buy a new printer.

The problem is somehow being caused by the wi-fi connection. I had some success by turning off my router to regain control of the printer, then did a factory default reset using the panel buttons following the instructions in the online manual. This apparently broke the wi-fi connection and I was able to turn the router back on without the recycling issue. I could then print using the USB connection from my desktop. Of course I can’t air print from my phone with the wi-fi disconnected from the printer, but I can now use the internet and print using the desktop. I’m standing by awaiting a more permanent fix from Canon.

Thank you.  I tried your solution.  I got all of the way to entering the random IP number.  I couldn't figure out how to convert from letters to the numbers.  It would only type letters.

My MX490 is doing the continuous power cycling and initialization as well.  I have never had the Wifi turned on or setup for the printer and it has always been accessed via USB cable directly to PC for printing / scanning functions.  I am experiencing the exact same thing as everyone else symptoms wise, just no Wifi involved whatsoever.  My menu just shows the Canon logo and all buttons are unresponsive as everyone else has mentioned.  For what it's worth, I am using third-party ink cartridges and have been for over three years with no issues.  Not sure if that is part of the problem or the entire problem as a whole.
