IX6850 Curved PGBK Check Pattern

[betager]

I had clogged my printerhead, and I cleaned it carefully.

But afterwards the nozzle check pattern for pgbk was warped. I triead varius functions (cleaning, alignment etc) but nothing worked. Is it broke?

I can still print photos on photopaper if i chose photo quality and not regular paper.

Thanks

I've seen other posts on this exact same problem.  They are all using Windows, so I'd like to advise everyone I'm using MacOS High Sierra Version10.13.6

As a result I agree with everyone else that it seems to be a glitch with the PGBK cartridges. Both original Canon and and generics.  I'm very disappointed in Canon and their lack of solution to their customers.

Yes this sucks big time, the printer business is such a scam. Everything breaks, ink is expensive, no support.
