It was necessary to realign heads.
I note that the ink is worth nothing that Epson BUT what is important here is to make the accounts: If I take the regular cartridges sold by Epson, it cost me 15.99 euros respectively for black cartridge (which was not an exceptional life elsewhere) and the colors it takes 48, 48 euros for the cheapest in origin. So basically the lot sold here would correspond to a total of original cartridges of almost 260 euros. So the price difference is well worth the quality gap found. I do not have the means to pay 50 euros a fortnight for my printer.
If we reverse the relationship, it's basically the cartridge to 80 cents. An excellent price / quality ratio when you know what you want (ie ordinary impressions, for the photo pass its direct path).
The ink does not bleed either. But it is not excellent, it must be admitted.
