MP560 won't print black ink

[Nate58]

My MP560 stopped printing black text.  Ink cartridges are full.  Test pattern prints all colors perfectly.  But when I print a doc from my PC or laptop only the colored text prints.

I've used the Utilities meno to do a clean and deep cleaning.  No help.

I've checked the print cartridges for stray bits of plastic that might keep ink from flowing.  No help.

I followed bgnewjersey's suggestion, watched this YouTube video on removing and cleaning the printhead (https://www.youtube.com/watch?v=ZheZf-vdho8) and did the cleaning.  Reinstalled and the printer still prints all colors including black on the test pattern but won't print black text when I print a document.

Any other ideas?

Thanks so much! Does this mean that the large black tank will never get used though?

Thanks for the suggestion of a workaround (for my MX860). I find that it does work, but very slowly prints black text in BLUE!

Perhaps the reason is that when I print the nozzle check, BOTH the black segments are missing (and incidentally, the letters PGBK at the top are missing while the bottom BK is present!). I've changed both black cartridges and cleaned and deep cleaned several times.

It makes me think that there must be a common printhead for both blacks, which must have failed.

If this is so, anyone have experience of replacing the printhead, assuming I can buy one?

Weird problem.  I can print with black ink from some programs but not others.  Particularly strange, docs of the same format, e.g. pdf, will print fine out of one program, most other programs it prints either as tho' it is running out of ink, or in some cases as if there is NO ink, i.e. a blank page.  I've run ever clean/align operation and reinstalled multiple times.

This worked!  Thx.

It works for me too on my MP560 but I can not copy, the solution is useful but not ideal

This solution also worked on my South American G4100.  However, it now will not copy!  Oh well!  Printing is more important and I do it more often than copying anyway!  Thanks!

Hi

Can you mention what are the programs that can print?

I am having printing issues now with Canon MP560.
