Canon Pixma MP780 Printer - black 3e fails to print

I cannot get the black 3e to print. I can get all other colors to print. I have cleaned the heads with a q-tip. After doing so twice, the printer now fails to align and continues to fail to print in black. Any suggestions?

Installed a new Print-Head, but that was no changes. I use refill ink, and it seams the BlackInkTank is not exactly on the Printhead and it is Air in the Pipe, i take the Printhead and the Ink-Cardridge in the Bathroom, and press the Ink-cardrige on the Printhead and take a hard breath and blow in the Air-Holes of the Ink-Cardrige until black ink come out of the Printhead, reinstall in the Printer, end it works well.

sorry about my bad english

The black print head is clogged. The reason why the black is clogged and not the photo black or any colors is that the black is pigment ink and the photo black and colors are dye based ink. The pigment ink is a particulate formulation that binds up when water is evaporated out of the ink. You need to buy a new print head the fix the problem. You can buy a new print head for $75 from precision

My canon PIMXA MP780 is not printing from the large Black

The black is the first to wear out on these printheads, you will need a new printhead, QY6-0049-000.
You will only waste inks trying to clean or deep clean, the best bet is to replace the printhead and if all else is ok you will get many more trouble free prints and better quality color prints.

Whenever I replace the 3E black ink in my Canon MP780 printer, the printer quits printing.  I have tried all the cleaning remedies on the menu.

because the print heads are gummed up with old ink and need to be cleaned with some alcohol and an old rag. do not get the ink on your fingers its hard to get off...good luck...

Black will not print

This may seem obvious but have you tried cleaning and refreshing the print heads? I've had a similar problem with only certain colors and the cleaning seemed to help.
