Hello, Please have a look at the images attached, I run the head cleaning utility and the print alignment utility several times, what else can I do? Thank you for any help

Do you use OEM Epson Brand Ink?

I am having the same problems. I have run the head cleaning and print alignment utility several times. Then changed the print cartridges and rerun all utilities. I am using OEM Epson Ink
