My i865 will not print text- I have changed the cartridges and the print head with the same result - blank pages Photo prints , colour images are ok so Im assuming the trouble is with the pigment black supply
our canon pixma ip3000 stopped printing black, fortunately within warranty, and Canon supplied a new print head which fixed it. Also had trouble with a batch of Choice magenta cartridges which were flooding the print head and causing other colours to disappear. Also replaced promptly and without question. Now all's well.
