If "foreign cartridges" are sold at a decent price, but they represent the colors correctly, the rest I do not care. Even if they are not recognized by the printer as a manufacturer-original. But if they are the yellows and greens impossible or extremely distorted and if you ferststellt after thorough troubleshooting that no equity or setting error, then the fun stops. Of these cartridges, which are obviously sold by several providers, I advise strongly.
