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.

OS X - Canon PIXMA MP780 printer won't print black


Unfortunately, I can't link you directly to canon's support pages, but if you go to this link, and enter won't print black and search, you'll get a list of possible solutions to troubleshoot this error. I'd start by checking your cartridge for ink,reseating it, print a test page, recalibrate the print head, etc. But that will get you started, at least.
If you have further problems please reply to this post and we'll help you get it sorted out...

Canon MP780 Printer Problem


Normal 0 Could have a corrupt driver.
Disconnect the printer or at least be sure it is turned off. I'd do both and when the CD software program asks you to connect the printer to the USB port, do so and it should again work properly.
Hope this helps. Bud
