Pixma MG7520 turns on but shuts off before I can access menu

[leafstar]

My Canon MG7520 was working perfectly until yesterday. It kept shutting itself off yesterday. Today it would start the process of turning on, but turn off before it would get to the menu. I know it's getting older, but it's worked so well until now. Is there anything I can do?

Ok, tks so much, I didnt notice. Now I did your fix and its running fine so far 🙂 Regards

Before you do anything. Go Online to the link in SamanthaW's Official canon fix and download the installer program. Once it is downloaded just shut off your internet, you won't need it since you have already downloaded the installer which happens to have the update file in it. As in my case the fix didn't work since I had my printer installed on WiFi and had uninstalled it as a USB printer.  If you haven't done anything "special" (named it or have to assign it a Static DNS) with your printer then you can safely just go into settings and do a reset on your printer which will clear the name, DNS settings etcetera  and make it like you just got it out of the box as far as settings go. Then connect your USB cable to the printer and install it on your computer as a USB printer. Then, turn off and back on your printer ta make sure there isn't any print job stuck in there, like mine automatically began printing a test page. Let the printing finish and again turn off your printer and turn it back on. NOW open the installer program and follow the three step dialogue. It should find your printer and by the time you go to step 2 it should take care of business. When it is done with step 3 (you will have to click continue to go to the next steps) You should turn off and on your printer. Turn on your WiFi and internet and see if your printer turns off like before. If you set it back up as a WiFi printer, you can keep the USB printer but then when you go to print you have to remember which one you want the USB or the WiFi one. I just delete the USB one so I don't have two printers listed, if you unplug the USB cable one will show as "offline". Good luck!

If you have got to the point that your printer no longer shuts off (turn off your WiFi in your house and turn on your printer and see if it stays on) THEN you should be able to get to the menus on the printer screen. Look through the menus and look for "reset" it should give you options to reset it. Some will have a "factory reset" others just "reset" touch reset and say yeah your sure (yes) Let it go through the Wiggly Woo magic stuff and Timey Whimey stuff. (Abracadabra, Kalamazoo, Shazam, what-ever) It should now be Reset. (Not talking down to you, just trying to make you laugh, its hard for me to not be silly)

Yes, it works like a breeze on a hot summer day while kicking back in my hammock sipping a Mint-Julip. Yes, your fix was that good! I like to control my DNS through out my home network so I used the Canon fix so I could reset my DNS to my home settings. No offense meant. Your fix and your assistance was timely, fantastic, spot on, functional, probably saved lives by getting medical facilities and pharmacies back in business. I had to print financial documents and get them in the mail within a few hours of your advice. You are still an angel and saved me money and time in ways you can only imagine. And yes, you are right there was no need to "fix" the issue any further except for my OCD convictions and my feeling it wasn't quite "finished". Always had problems with O.C.D. shouldn't that be C.D.O.? Leave it to psycho-babelists (Psychologists) to give an analysis of a psychological  disorder dealing with a problem where things out of order cause neurologic events and stress where the diagnosis is an acronym amalgamation which in itself is out of order! (It is "A.B.C" NOT "C.A.B."!!!! morons)😁

Scroll up and look for SamanthaW's Official Canon Fix. Or Sheri99's fix.

With MX492 the printer powers on, but the input pad/buttons including the power button are totally unresponsive.  The yellow/green indicator light continually flashes.  I don't have the router turned on and I turn off WiFi on my laptop, USB is connected from laptop to printer.  When I run your update program there is a "Printer cannot be found" message.  Can you clarify your update instructions?

Hi, I followed the instructions someone else gave below to turn off wireless to be able to turn the machine on and print again. Now I can also not scan, even when the USB cord is plugged in.

Thanks

****Turn off your HOUSE WIFI to be able to get your printer to work long enough to do anything.*** Your printer connecting to the WiFi is part of the problem and is why your printer keeps shutting off.  Down load the installer so you have it on your computer, turn off your house-hold WiFi then deal with the printer. The WiFi router needs to be turned off once you download the installer. THEN the printer should allow you to do things with it. You will need to install your printer as a USB printer or you will get the message "Printer not found."

I tried all of that several times and I never saw the word reset on my printer but I did see something that said cable less and I clicked on that which didn’t do anything either. I have tried everything I have read and thought of several times. No doubt I have missed a trick here and there. But I have had no success. Like others, I was not able to download the recommended software after many tries. Rather I couldn’t get it to move on and install. I will try to call Cannon tomorrow but maybe they’re closed forever, who knows?

Susan did you search for my post. "EASY FIX" if your printer won't stay on? If you found that and changed your DNS to .000.000.000.001 and it still isn't working you would be the first to have it not work of dozens of people who have done that and it worked for. If you haven't found it, please do. Your problems will be over.
