Question about Canon PIXMA MP780 All-In-One InkJet Printer
Black ink cartridge, 3eBK, doesn't print test pattern nor does it print anymore. Tried new canon cartridge, cleaning, deep cleaning. Tried head alignment, but not sure if done correctly. Tried auto head align on printer menu. After it started a few black and blue square boxes were printed on a sheet of paper and only got message,"Head Align Failed." Help!
You most likely have a faulty print head there on the black cartridge, try cleaning the contacts and check your warranty status for repairs.
