All of a sudden my printer will print in any colour except black

Pixma MG6250

All of a sudden my printer will print in any colour except black, I've run half a dozen deep cleans, run the check nozzle, it appears as though Black: PGI-525PGBK is the culprit if the nozzle check is to be believed.

I swapped out a 3/4 full tank, with a brand new one, just to make sure.

NO DIFFERENCE

Thank you for responding.

I'm in Australia, I appreciate being allowed to post a question.

Okay so the Pixma MG6250 isn't sold in the USA, it is still a Canon product isn't it?

I have been reading posts varying models, that are all experiencing the same problem.

Is there no general guide for this problem?

No, because different models have different menus. We recommend reaching out to support in your region for immediate technical support.
