After installing aftermarket cartridges I am getting lines in my pictures

[TomP86]

Hi guys. I installed some aftermarket printer cartridges into my dads Epson Workforce Pro WF 3835 that I filled myself using aftermarket ink. The printer recognizes the cartridges no problem but when I print pictures they have lines with varying shades of colour in them. Do anyone by chance know why that would be and potentially how I could fix it (without buying new epson cartridges)

Hi all. I fixed it by cleaning the printer head a couple of times

The print head may have received ink sediment to cause clogs when you changed the cartridges.
