My advice is dont use Cheapo cartridges if you need Very good quality photographs as the colours are slightly off, especially the blacks they have a greenish tinge.Use the manufactures brand, but for quick printing like letters or stuff like that its ok
I used to refill my own but the colours were shite so stopped, but after a while it knackers up ya ink nozzel either blocks it or the printing goes pixelated or lines thru.
if you are goin to buy some try
