Is there maybe someone else out there in the #photograpy or printing bubble with a Canon Pro 1100 and has massive problems with the matt black ink (MBK)? I need to run a head cleaning nearly every week now because the printer just stops to print the MBK color. That sucks and is expensive as hell.

And if you have this printer without any problems with this or other colors I would still be interested in your feedback too. :BoostOK:
