iP4300 missing exactly the same lines of text

[tkcanon10]

My iP4300 is missing exactly the same lines of text using the PGBK cartridge no matter what I have tried right down to missing exactly the same top half of one line of text and the bottom half of anotherr. Aside from missing lines there is no smearing or missing ink on lines that do print. I have changed the cartridge, done deep cleaning, attached the printer to two different computers, and tried unplugging and replugging from the wall plug. About 3 lines of text are printed and then about 3 lines are skipped down the entire page. Seems like clogged nozzels would not produce such a consistent result. I searched on the Internet and find plenty of ink issues but nothing like this. Seems like getting exactly the same result must be a clue. Can anyone help? Thanks so much..  P.S. Page prints perfectly using BK cartridge or any other color.
