banding/printhead failures? on multiple nearly new Canon iX6850

I would go along with PeterBJ, because I also reckon your ruining the print heads with compatible inks and carts, yes I know you have used them before without issues, but that was then and this is now..

All of these newer Canon model printers have issues with compatible inks, so unless your prepared to use only OEM ink/carts then the same thing will keep on happening, your last resort is to try a pigment ink printer..

That would help enormously...

I want to agree because it would be an answer but why would this happen with the Canon inks too? Because the latest printer started doing this before i replaced any inks.

Thought I'd update incase anyone else is having the same issues.

I upgraded to Sonoma, and my issues are solved. I'm 99% sure it was a driver/mac OS problem. No way to prove it but I'm not having the banding any more and print quality is much improved.

(can't print PDFs from Acrobat in the correct quality but thats a new thing they broke with the update)
