The black ink port on the printer is not drawing ink. The cartridge is full but the ink is not being pulled. I have used a swab to clean the area but that has not helped. Also, I have purchased a new ink cartridge and this did not work either. Is there something else that I might try to do.
I have a Canon Multipass F80 which sometimes has this problem, especially if I haven't been using it for awhile. Usually what works, I take out the printhead, removing the cartridges first. Get a shallow dish of hot water and soak the area where the ink is emitted until the old ink has been soaked off, also, will swab with alcohol to hasten the process, repeat a couple of times until the water is clear. Dry well, make sure the cartridges you reinstall are not "old" so they will still flow ok. Usually this solves the problem. By the way, I would rather do this than by a new cheapy, because this printer will accept 3rd party cartridges. The new printers with the "chip" will not use 3rd part cartridges.
The printhead might be clogged. you can try to execute cleaning into the printer driver utility. notify me if this solves your problem or not.
