On test print the BCI 3e box grid that test prints has breaks in the lines of the boxes. I have carried out 7 deep cleans and still get same result.
Any suggestions will be gratefully received.
My thoughst are repair shop for installation of new jets but it might not be cost effective as printers are so cheap now.
Just printed out a picture of Mona lisa and she has offwhite horizontal streaks across the picture.
