I have read numerous articles of the same issue - PGBK won't print on my PIXMA ip8720. As with most commentors, cartridge was replaced, printer heads taken out and cleaned, drivers reinstalled, but still the same issue. All other colors are fine. Is there anyone that can provide an answer to this issue, CANON reps apparently cannot. I would hate to throw this printer out and go to another brand over what probably is a simplistic fix.
