My Canon PIXMA iP6600D printer suddenly will not print black ink. At the time I thought it was just out of ink (that cartridge was low and I knew I needed a replacement) but I have since replaced it and the printer will not print the black (other colors appear just fine). I have cleaned the nozzle head at least a dozen times and deep-cleaned it at least 4, and it will still not print black (and this is with a new cartridge). I have tried to print the auto head align but I get this message after it tries to do it:
" Auto Head Align has failed. Press OK and repeat operation. (see manual)"
And I have looked in the manual but there's no information on this. The manual's advice (if there are 'white lines' or whatnot in whatever is being printed, which I figure is the closest to my problem) is to wait 24hrs and try cleaning the nozzle again.
Can anyone help or suggest anything I haven't tried yet? Worst comes to worst, is this something I can bring in to Best Buy to have checked out and/or fixed? D: I'm at the end of my tether here frustrated to tears.
