I bought these in November cartridges for Workforce WF-2540. At first, no problem, the impression was nickel except for a small trouble with the Cyan cartridge, the blue prints were cut in the middle by a large white line, but it did'nt saw that words were still very legible. Unfortunately, when I had to change the cartridges, a HUGE problem occurred, and all my impressions were colored pink. ALL, everything was pink, plus any other color not working except black (which was still pink). I tried to return the cartridges ten times, saying that it was a contact problem, but to no avail. I find myself today with pink prints. I highly recommend purchasing these cartridges, I'm not the only one who had this trouble because I had a friend recommended these cartridges, and the same problem occurred. Certainly, the price is attractive because much cheaper than original EPSON, but if it is not able to print correctly, it is not worth it! Very disappointed with this purchase!
