MG7520 the type of print head is incorrect?

[Alex123]

I suddenly got "Support code 1403 The type of print head is incorrect. Install the correct print head." error today

I bought this July 2015 and it happens to "break" just 1 month after warranty expires?

I try to search and get many things about removing and reseating the print head but their is absolutely no instructions I can find on how to do it with this...

I have the same error....One day the printer was fine. Two days later I carried it into the kitchen on a bit of an angle because it was heavy..Now I have printhead errors and can't print anything..Of course I recently purchased all new ink..
