Epsom Stylus C65. 5 new Epsom cartridges. The verticle lines are a pale purple colour evenly spaced 10mm apart,
Would love to know how to fix it.
Thanks.

Try several cleaning cycles alternating with a nozzle check each time. You might have to repeat the process several times but it should work eventually as long as the print head is not damaged. This is the main drawback of fixed print-head printers. Tip; to save paper: after performing each nozzle check, turn the paper over and make another run, then cut that section off and run the same piece through again. That way you can make many nozzle pattern checks on one piece of paper.
