Anyone come across a problem like this before ?\n\nCanon iP3000 working fine until a few weeks ago.\n\nNow won't print in black.\n\nI've changed the tank, gone through a cleaning cycle or 3. gone through \nthe same thing with deep cleaning cycles.\nWhen printing a windows test page I get the windows logo in the top left \nperfectly but no text. I've gone through some of the printer forums and \ncleaned the head, no change. When I take the black tank off there's ink \non the sponge but it's not going anywhere ?\n\nIf I change the text color in word etc it'll print, but it refuses to do \nanything in black. A nozzle check prints 6C and everything below. What \never I do there's not a trace of black on the page !!\n\nAnyone ?
