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. (I am still laughing-hang on) You are an angel! Your message to me arrived moments before I dropped an 8 pound sledge hammer on my printer. I had just purchased 120 dollars worth of Canon pure-bread ink a few days ago for this thing. I printed a few pages on 5-30-2022 and was stunned that today it was DOA. I started reading your message and got to the pay me in VenMo and my blood boiled. I thought Gee, I was right it was a Russian Hack! And.. me, bent on discovering who you were and why you would perpetrate such a dastardly attack on my right to print nonsense and cat memes! I carried on reading to discover the VenMo was a joke. Wiping the sweat from my brow I hungrily chewed through the rest of your message, relishing every word until satiated. I followed your instructions as if I was a 3 year old learning the most important thing in my life! I proceeded to diligently carry out your instructions, blindly, without questioning the knowledge and precise steps. I took those steps unerringly, unfaltering, my first steps to everything. Besides if I fell I had already forgotten about the boo-boo, I will survive, my will enslaved me, I would not be denied. It worked perfectly! I cannot thank you enough. I am sure canon doesn't post the solution because they want that 20 dollars from all the people with Out of Warranty printers. That could back fire by not selling printers to customers, then what do they have? 

Your reward for your informative message to me is, sleep well Sheri99, you wear a golden halo and are cloaked in gossamer wings in my eyes. Thank you for your timely informative assistance. You saved me in more ways than one, and you saved my printer from a unrecoverable fall down a 5 story staircase. My printer thanks you and I thank you.

You are hilarious! Thank you for that reply, it was awesome!

You are hilarious!! It was like reading a novel...lol..

Question, why would you spend $120 on ink? I buy the ink on Amazon. Office World ink and a box of 25 cartridges for $12

[trehki]

I buy real Canon brand and even with Amazon things are priced for the area you live in. A full set of ink for me in my area is about 110 dollars and then there is tax and since I don't buy a membership to Amazon I pay for shipping in some cases. When I went to buy ink no one had a full set in stock-usually about 85 dollars so I ended up buying from several different venders, each with their own shipping and prices. Sure I can buy meat at the grocery store for reasonable prices but technology is a beast here. The closest store for technology here is Walmart! Take that and run with it for a minute. Its June, I shoveled snow last week. Tonight's forecast is for 33 degrees, did I mention it is June? Now you might understand the controversy of online tracking by Google and all the rest. That's how they know where you are and just how much they can get you for. AND they base the advertisements on your area and charge you tax on the location you ship it to.

not all heroes wear capes, Sheri. Thank you for stepping up, making that $20 phone call, and getting the official low down for us until Canon gets their act together haha 🙏

Thanks so much for this fix! I had the same issue with an MG 7520 that worked flawlessly for about 6 years - though not with a router, but with a T-Mobile WiFi hotspot MiFi device that I use for internet (very rural and no other options). I followed these instructions and the printer came back on. I was set up to try it as a USB printer, but decided to try turning the hotspot back on, and amazingly, the printer connected and after going through an endless cycle of maintenance, it printed.

My question - will this fix "stick" when I turn off the hotspot and reconnect at a later point, or will it need to be reset each time?

Canon has posted a notice about the issue - but their suggestion is to use the printer as a USB - not connected after their fix of just turning off the LAN. Seems that this fix of resetting the DNS did allow for wireless printing, but will it continue to work each time - that is the question.

Will Cannon be addressing this so that we don't have this issue again??

Again - thanks for the help and fix. I was also about ready to order a new printer, but for the moment, this has resolved the situation. 👍

@HLily To answer your question the Wi-Fi DNS fix did work repeatedly for me and so did the USb Fix. HOWEVER SamanthaW released Canons Official Fix, Scroll up to find it. It is just above one of my previous posts. So far the Canon Official Fix has been working. 

[HLily]

Thanks so much! Yes, I did see the Canon Official Fix, which seems to involve the software update. I think I'll see how this fix continues to work before I do that update, but will keep it in mind as a backup if the issue starts to happen again!

Thanks for the reply.

Just wanted to say that I shared this fix over in the Ask Woody forums in case anyone there might have the same issue. Gave credit to sheri99 and this forum. Hope that is OK with everyone here!

@leafstar You may want to update this with a fix update that Sheri99 just posted! That way everyone can see it since I don’t think anyone is reading all the comments.
