We have been having a problem with printing black. It started with small smudges and then streaks across the page. It has progressively become worse and worse. I have run multiple cleanings, deep cleanings, and ink flushes. After the ink flush, the printer will no longer print in black AT ALL. Upon inspection of the ink lines, there does not seem to be any black ink in the line. Please help. I have run multiple cleanings and flushes after the Ink flush and nothing seems to help refill the line.
