Pixma 7520 ink incompatibility

[CatClax]

I have the 7520 printer, and it is a workhorse. I just ordered ink from Walmart. The box I clicked on, I believe, said Canon 250 ink, but when I received the ink and inserted it in, my printer the printer message said it did not recognize the cartridge and the printer would not work. I have called Walmart to explain the false advertising.  The Canon people need to look at the ink on the Walmart site that they are trying to pass off as Canon ink for the 250 and 251 cartridges.  This is super deceptive!  I let Walmart know my concerns.  I attempted to call Canon but could not figure out how to talk with a human.  I hope someone with Canon sees this post and checks this deceptive practice out.

Thanks for joining the conversation, CatClax!

So that the Community can help you better, we need to know exactly which Canon printer model you're using.  We've made two different printers with the number 7520 in their name, namely the PIXMA MG7520 and the PIXMA TR7520, each of which uses different ink cartridges. That, and any other details you'd like to give will help the Community better understand your issue!
