I have a Canon i960 which has been working perfectly since I bought it about 2.... maybe three years ago. Recently, however, it has decided that it does not recognize solid balcks. It does print a kind of vague version of a greyscale photo, which means that the black nozzle is not clogged. The cartridge is full too. It prints all other colors just fine. I have tried the printhead cleaning and deep-cleaning and have re-loaded the driver three times. Any brilliant ideas out there or do I have to go and buy a new printer???
