When I printed a nozzle check recently, I found that the magenta pattern was totally missing. The other four colours and the black were OK. I have tried the cleaning cycle several times, but still get no colour at all for magenta. I have replaced the cart with a new one and the same problem persists.
Has anyone got any ideas of how to solve this problem? Is it easy to get to the print heads and clean them as I guess it looks as though the magenta printhead is totally blocked.
