PIXMA PRO-200 Error 520E

[Leshii413]

Purchased this Jul 5th, 2024. 

It is just outside warranty, with less than 600 pages printed and of that, maybe 80-90 photos.

Did not use printer Dec 24' to May 25' due to extended travels, returned, figured it sat that long it would need new ink, ordered a kit from Canon USA on amazon, verified storefront page, installed new ink, added new photo paper to print some test pictures for a new design I was commissioned to do. 520E error. 
Restarted, same issue, put old ink carts back in, as they sat upside down on the tablet next to me so they were un tarnished, same result.

Now nearly $200 out on ink, and a literal 40 day window from the warranty being valid.

Any fixes? Please no just upgrade. I had to do that after the smaller printer by canon already. And that one still prints fine in anything except grayscale, just not the detail nor volume. 

I need an actual fix.

It could be that the cartier’s are not correct placed

Yes I have seen, and replicated that attempt. Prior to posting, I searched for 520E, 520e 520 e error code, pixma pro 200 error, pixma 520e, Pro-200 520E and more variations on forums, Google and reddit. YouTube gave a few suggestions as well.

Adding as I did not reply to it, cartridges checked multiple times on seating too.
