Hi
I've changed ink from set up I had when purchased to new cartridges. Checked the vents on the cartrigdes, completed printhead clean - twice. I think I've followed all the on screen proceedures.
I get the 3 black lines ( 1cm wide)- black, grey and light grey but no colour, the 3 lines of letters and some thin lines below but no colour.
The printer reports the ink is low but when viewed on PC all the ink is full - which it should be as they are all new.
I've never been able to register my printer because I can't read the code when printed off.
