Canon MX492 All-in-one devices are restarting repeatly with WiFi/Internet connection

Stop - Pixabay[German]Short information about a possible problem with Canon All-in-one printing devices. There are reports from users that Canon Pixma MX492 (and other Canon) printers suddenly cause issues when there is a Wi-Fi connection to a network with Internet access. Without a Wi-Fi connection (or Internet access), there are no issues. It seems that a DNS issue is the root cause of device restarts. And the question is whether anyone else is affected? Addendum: Canon provides a firmware update to fix that issue.


The Canon MX492 is a wireless all-in-one inkjet photo printer from the Pixma series, which can fax, print and scan. The devices can be connected to a network via Wi-Fi connection.

Issues with the Canon MX492

The request reached me via a closed group on Facebook, where someone pointed out the problem in a short message with reference to a discussion at (thanks to Max S. for the tip).

On, a concerned person who opened the this thread writes about the following difficulties with a Canon MX492 printer in connection with a network:

Canon MX492 Restarting Repeatedly after connecting to Wifi

It keeps turning on and off repeatedly every time I connect it to the wifi.

If I disconnect from the network, it works fine.

I've already reset my network and did a factory reset on the printer.

What could be the issue?

The device switches off and on again or remains in a kind of restart loop – as soon as the printer is connected to a network via Wi-Fi. Thus, the devices are virtually unusable. If the Wi-Fi connection to the network is disconnected, the printer works without problems. Remedies such as factory resetting the printer or resetting the network (presumably the Wi-Fi connection to the network) did not help, the affected person writes.


This could be an isolated issue, but the post has already received 65 comments and another user confirmed this issues with Canon PIXMA MX490 series printers (and possibly other models) getting stuck in a boot loop. The following posts were referenced:

In the latter post, someone posted a video of the printer malfunctioning. Also in the Canon forum there is this thread about the issue.

Problem with Internet connection

Currently, it turns out that the problem is related to the Internet access of the Canon MX 492. In the meantime, there are two workarounds.

Workaround  for DNS problem

In this thread, someone writes that there must be a DNS problem and links to the workaround described here that might help.

I solved my problem by turning off the Access Point (or unplugging the internet cable from the router's WAN port). The printer will turn on normally.

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.

Once configured, press OK.

Select the 'No' option and press OK.

Wait a few moments to complete the configuration.

After returning to the menu, press the 'Home' button on the printer.

Turn the Access Point back on or reconnect the Internet cable and retest.

For me this solution worked. As I do not use external services (Google Cloud), there is no need for my printer to consult on the Internet.

The affected person disconnected the Wi-Fi connection to the router and then manually entered a DNS server (whose IP address – 192.168.X.X – an IP that is unoccupied in the network, see also here). It seems to help with affected users.

Just block Internet access for the device

And I got a feedback from German user to my blog post, who just blocked outgoing Internet connections for Pixma Canon MX492 within it's router firewall, to avoid this continuous reboot cycle. Might help also for other Canon printer models, if affected. Anyone with the same experience?

Addendum: In the meantime, a number of affected people have reported here and in the English blog. In addition, it appears that not only the Pixma Canon MX 492 All-In-One printer is affected. Also the Canon models Pixma 6550, MX490, MB2010, Maxify MB 5350 and MG7520 seem to show the effects. However, the list does not have to be complete. The cause is unknown – no idea if it's a firmware update that's now causing the problem. Unfortunately, there are also (vague) indications that interrupting the Internet connection does not help with all those affected – I cannot currently judge whether this is something for the worse, or whether it is due to inadequate communication from those affected, which paints a false picture.

Addendum 2: Canon provides a firmware update to fix that issue, see Canon PIXMA/MAXIFY printers (MX492 etc.): Manual firmware update fixes restart loop.

    My Canon Pixma MX492 just started having this perpetual reboot issue yesterday. In the middle of copying, it flashed a message "Check ink." The ink was fine. Then came the reboot loop. I've had only two printers for the last 20+ years – both Canons – and this is the first problem I've encountered. I guess it's time for a non-Canon printer!

    • Robert says:

      It's something strange in the middle, my mb5350 canon just started few day ago to make the same think.My printer it's connected to the WiFi to make my life easier but now it's useless with WiFi….

    • Brian Miller says:

      So if any of you are as Tech illiterate as I am oh, I found a way to disconnect your printer from the Wi-Fi if it won't even turn on like mine to access the screen. It's just rebooting over and over. My internet is through Spectrum. On your spectrum app you can click on devices and pause the connection to your printer. I did this in my printer is on normal now just no connection. This may have been super obvious to everyone, if so forgive my naivete!!

      • AmyinFL says:

        Thank you so very much for taking the time to post this simple fix. I work from home and use this printer and have a deadline that was looming. Your suggestion worked for me!! I had looked at a few of the technical ones and thought I'd have to just by a new printer haha.

    • B Smith in Ohio says:

      My Cannon MX 492 also started this continuous loop reboot on June 2 of 2022 as well. weird. I'm also on Spectrum internet.

    • April says:

      My problems started then too. 🤬

  2. Julien says:

    This happened to me today when I booted up my printer for the first time after moving. New wifi connection so printer was working fine until I finally connected it to the network. Now infinite reboot loop without ability to fix it.

    • guenni says:

      Shut down your access point. Then try to find out, how to block Internet connection for your printer.

  3. Sarah Lockwood says:

    This started happening to me today but it's even restarting constantly when it's not connected to internet either. I can't get any buttons to work – can't access menu. It just keeps making all kinds of noise, shutting off, turning back on – endelessly.

    • Ernie D says:

      Same issue here. I have read where Canon is having the problem and is trying to fix it.

      • mike b says:

        im having the same exact problem with my mx492 and cant get it to stop either. didnt notice it until i tried to print something off my phone this morning

      • Montie Essman says:

        Same with mine! Had to unplug it because none of the buttons work. And it irratating

        • Misty S. says:

          I am having the exact same issue as well. I try to make the printer work offline and then connect a USB cable, but it continues to restart over and over again, so much that I can't get access the menu buttons.

      • John B says:

        Same problem with my MX492. Signed in to Verizon G3100 router to search for printers wifi connection (in devices) to block it. Needed patience here as printer only showed as a connected device during the time it was trying to start up. Eventually was able to block the wifi connection in router. Unplugged printer then plugged back in. Printer started normally without wifi connection. Reconnected using printer WPS setup routine then unblocked the same wifi connection. Test page printed. Scanner also working. Did not test fax function as I rarely use it. Did not have to reinstall drivers.

        Hope this helps.

    • Mary Ann A. says:

      This started happening to me a couple days ago. I found John B.'s reply most helpful. I disconnected/paused from xfinity wifi. I can make copies and can print from USB connected to computer. I reconnected using printer WPS setup routine but I could not print and the printer went back to the same useless state of being unable to print or copy in any way. For now I will live without the wifi connection. Thank you so much John B. So glad I saw this thread as I was 5 minutes away from throwing the printer out! And I had just purchased new ink cartridges the day before (which cost as much as the printer) Thank you, thank you, thank you!

  5. Nick Stobart says:

    I started having this problem a few days ago with my Canon MB2350. When connected to the router, the printer repeatedly shuts down and reboots after ejecting a sheet of paper. I agree that the issue is related to the internet access. I blocked the printer on my Fritz box Filter tab which resolved the problem. I then tried to set up a unique profile that blocked internet and assigned it to the printer. I then unblocked the printer again allowing it to use the new profile with no internet access. The printer almost immediately went back into the shutdown cycle. I will try the DNS solution when I have time but for now I can still print via Wi-Fi and have stopped the irritation.

  6. Jen White says:

    I just got on internet to research this same issue…just started today for me. I guess I'll try the above suggestion.

  7. Jen White says:

    Does anyone find it weird that this is just now happing to so many people?

    • Stephanie M says:

      My thoughts exactly! I'm having the SAME issue!

      • Montie Essman says:

        I have an MX492. Never had any problems. but now it keeps starting up shutting down. I have unplugged and plugged back in so many times and it wont stop. I can't even shut it off. I have to unplug it to stop. What the heck is going on?

    • Nick Stobart says:

      Extremely unusual. I am wondering if it is Windows 11 update related? I haven't done a firmware update in my printer nor on my router.

      • Sam O. says:

        A friend with an MX492 connected via wi-fi to a macbook has the same problem. Not a Windows issue….

        • odotcri says:

          I believe it has something to do with a recent firmware update. Got a notification saying there was a new firmware update, and after it installed, a few moments later my printer started boot looping when connected to the Wi-Fi.

      • Kate says:

        I have windows 10 and its happening to me as well. I just am thinking that perhaps an auto update has messed it up. Not sure.

    • Jessica says:

      here i am with the same issue when i really need something printed.

    • April says:

      Yup!! I am glad I am not going crazy but this seems like it was intentional from canon to put a bug in it.

  8. Oz says:

    Strange thing, the solution to block internet access to the Canon PIXMA worked wonderfully, i wonder what it was trying to send out to www. Hmm, questions questions

  9. Deborah O'Neill says:

    I started having the same problem as everyone else yesterday. Even when I shut down the printer manually, it starts back on its own. I was forced to pull the plug from the wall. How do I fix this? Please be simple with the directions as I'm in my 70s.

  10. Donna says:

    I am also having this issue and I have 2 Canon MX792. It started last night,6/1/22. I unplugged it over night. Still happening. I took the other one out of the closet and it also is doing it. I had bought another one due to the fact the printer no longer worked if there wasn't Genuine Canon Ink being used. Crazy thing…it worked just fine for quite a while with other inks…then about one year ago, it wouldn't recognize generic ink!! Hope Canon fixes this issue or I too will be moving on from Canon.
    Just for the heck of it I turned off my WiFi router and sure enough the printer is fine. I just turned my router back on and so far the printer isn't going Whacky…..yet…Very weird.

    • Donna says:

      Of course the printer is not connected to the WiFi now…I'm going to try using usb/printer cable to print my work.

  11. Cannon Fodder says:

    Blocking it from internet access in my firewall worked.

  12. Amy H says:

    Yeah my MX490 was stuck in a god awful reboot cycle. I just blocked it from my wifi and it is working again!

  13. Goa says:

    My printer just started rebooting constantly. How do you disconnected from the inte4net when you can't press any buttons?

    • guenni says:

      Pull the plug of your Internet wall socket as a first action – then try to block the device via router firewall.

    • Nick Stobart says:

      You may be able to go into your router settings (via web browser) and block the printer. If it has WiFi, your devices should still connect to it as a WiFi printer. It ois just no lnger connected t your Network.

  14. Kian says:

    Manual DNS setting with fixed IP resolved the problem on my Canon Maxify.

  15. Ged says:

    I have a Maxify MB5360 with the same issue. I will try the manual DNS fix but shouldn't Canon be across this with so many devices affected.

    • Ernie says:

      Same issue here. It's definitely a wifi issue. I shutdown my modem and router and the rebooting stopped. I was also able to see the canon menu again.
      After turning on the network it started doing the same thing again. UGH!

  16. Frank Plonus says:

    I have the same problem with my maxify 2350.
    Endless rebooting. With Fritzbox switched off, normal booting.
    Going to try one of the solutions shown here

  17. zach says:

    blocking access to internet did not solve this problem for me

  18. Stacee says:

    I'm having the same problem with my Canon 490. When is Canon going to fix this problem, I need my printer, it worked fine last week.

  19. Jeri says:

    Same problem. Constantly turning on and off. I'm not good at all with technical stuff. I've no idea how to do the Firewall blocking or change the dns or whatever…sooo frustrating.

  20. jp says:

    Both MX492 printers in our house started this 6/1/2022 at 9pm PST. Incredibly frustrating had to unplug them to get some sleep.

  21. C Owens says:

    My Cannon 492 started the power up–shut down loop at 6/1/22 in the middle of night as well. Definitely a software /internet issue. Turn off router and stays on.
    Probably my last Cannon

  22. Marilyn says:


  23. Rakesh says:

    My Canon MX494 started doing the same reboot cycle today. I switched off the internet router and then I finally managed to manually connect it to my Mac with the printer cable and it worked. I also reset it but as soon as I switched the internet router back on it immediately went into the boot loop again. Canon needs to urgently resolve this issue.
    South Africa.

  24. D Mac says:

    I have Xfinity internet service. I went into " my xfinity " and paused the printer ( access to internet) and can now print via Wi-Fi.

  25. Judy S says:

    I'm having the same problem with my MX492 – started in the middle of a print job – continual rebooting and will only stop if I unplug it! Left it unplugged over night but as soon as I plugged it in again, the same thing! None of the buttons work, can't access the menu. Went to the website to try and do a reset but nothing works! I need a wireless printer so I can print from the computer, phone or iPad! Finally went out and bought a new printer! As this appears to be a Canon problem, I think Canon owes us a partial refund toward a new printer!

  26. Joan says:

    I'm having the same exact issue.
    When will this be resolved?

  27. Pat O says:

    This fix worked for me. Unplugged printer. Unplugged the modem to router connection, meaning disabled wifi. Plugged printer back in. The LED menu screen lit up normally….(instead of just saying "Canon")…. and was able to copy a page manually. Yeah! Plugged modem back in to router, meaning enabled wifi again. LED menu screen still normal. Printer works fine now. Will print from computer or ipad via wifi. The above apparently got it out of the "restart loop" it seemed to be stuck in.

    Problem started today, after the power cord accidentally came out of back of printer, while power was still on. Warning box later came up saying correct way to unplug is only after turning printer off.

    Hope this helps!

  28. Sumit says:

    This issue has happened to me yesterday and still unresolved

  29. Amy Souci says:

    I started having the exact same issue starting two days ago. Has anyone heard from Cannon that they are looking into it

  30. Kimber says:

    On 06/02/2021 two in morning my cannon MX492- started it has not stopped yet. Unplug for 2 days, plugged it up and it turns on and off

  31. Brian Miller says:

    Well, I'm glad to see I'm not going crazy! That doesn't change the fact that this sucks and I need to use the printer! LOL I sure hope Canon does fix this! I will save this thread to my home screen to see if any updates appear. I am not tech savvy enough to do my own IP address and all that jazz. I guess I could try to Google it or YouTube it!

  32. edfultz says:

    same thing with my MX492 yesterday morning started doing weird stuff. I am annoyed.

  33. Tony Indge says:

    My 3-4 year old Canon MX490 started the exact same problem on May 1st 2020
    Located in Maryland US

  34. Bill Marvel says:

    Same problem on my MX 492. Green light flashes continually, printer reboots, only shows CANON in the display and no buttons work. Can't even do a hard reset. Only way to shut it off is unplug. Mine was on WIFI but my wife's was not and just on USB. Thinking I had a printer problem, I set hers up on my computer with WIFI and had the same problem. Here's the kicker — when I put her printer back on her computer with the USB connection, it now has the same exact problem my printer has! Did trying to set it up on WIFI cause this or did some generic problem in all of these MX 492s?? Seems the latter from reading posts.

  35. Craig says:

    same here. beyond annoyed and nowhere near tech savvy enough to reboot/route/fix this problem.

  36. Tom D says:

    +1 for this article. I had the same symptoms on my MX490. The instructions remedied the problem. I'm now curious to see how Canon intends to distribute a patch for this blunder; given that the workaround is to essentially incapacitate querying of the DNS server.

    UPDATE: Manual firmware update is required –

    • Mary Ann A. says:

      Yes. Tried the manual firmware update today, 6/5/22 and it worked. Can now use the printer using wi-fi (and it's copy function). Seems to be back to normal. Thank you!!!

  37. Mary Ann A. says:

    This started happening to me a couple days ago. I found John B.'s reply most helpful. I disconnected/paused from xfinity wifi. I can make copies and can print from USB connected to computer.

    • Mary Ann A. says:

      The manual firmware update worked. Wi-fi functionality is back working. Thank you to all.

  38. Nick Stobart says:

    The update appears to have worked for my MB2350 too. Thanks everyone for your support and guidance.

  39. Keoni Ahlo says:

    UPDATE: Canon just released an updated firmware for our affected printers on 06-10-22!
    1. First, you will need to download the firmware update from Canon USA's site, then plug your printer into your computer via USB cable.
    2. Run the updater app, and it will automatically upgrade your firmware on your printer. 3. Then the app will instruct you to pull the power plug from your printer, then plug in to finish.
    4. What they DON'T say (at lease on Macs), is that you will need to delete your printer from your System Preferences–>Printers list, then re-add it.
    5. ALSO, if you messed with your DNS settings as a workaround, you may want to reset your wifi settings (or select Auto DNS on the printer). I'm printing via wifi again!

    Aloha :)
