Hi
I seem to have vertical lines appearing on my prints, which i'm thinking is to do with the magenta cart as it's not on all colours. It was fine one day and then the next lines are appearing. The cart was low so I put a new one in and have done a few head cleans and a head flush and no change. The nozzle check is perfect across all 4 colours though. any ideas? am I suppose to be cleaning inside at all as it's difficult to see anything as it's all hidden or covered up.
Thanks
Lianne
