Did you get a service manual for that printer? Are you having this problem on all 4 components C M Y K?

You wouldn’t be using 3rd party toner by any chance..?
More information would help...

I do have 3rd party toner. If I get canon toners would it adjust back?

Yes all 4

If your problem is coming from the use of 3rd party inks then you’ll need to recalibrate the printer to accommodate the new inks by using a recognised test print..

Yes all 4

Ok at this point we would ask you if possible to print an internal printer diagnostic test print.

My guess could be the fuser or the corona wires.

Did you clean the coronas?

 

[Eddybravo]

How do I clean both of those
