I am having difficulty in getting my Pixma iP4500 to print correct colours. In particular the greens are too yellow and even though I have tried to correct it in the manuel settings I cannot achieve really dark greens. With better quality papers the problem seems to be even greater. I have checked the ink cartridges and even flushed the print head with flushing medium wihout any improvement. When I run a nozzle check the result is O.K. Has anyone any ideas?
