Question about Canon PIXMA MP780 All-In-One InkJet Printer
It is a new tank, correctly installed. It won't print any black colour
Looks to me like an air lock in the system.
Have you just changed the black cartridge because of an error message and did it print up to the point where you just changed it?
Just replacing the cartridge with a new on can sometimes lead to an air lock in the small ink feed system.
Does your cartridge have the writing head at the bottom or is it just an ink tank, in which case it could defiantly be an air lock.
Try a cleaning cycle, and leave the printer for a few hours to stand and let the air lock escape naturally. Running loads of cleaning cycles will use a lot of ink, so don't be too hasty.
