I ordered the pack 4 cartridges but did not recognize my printer pas..j'ai contacted the seller who referred me a pack without any problem and he gave me an address to send it to my first toll load. Unfortunately the second pack does not plus..alors not finding work that normal, I contacted Epson and have brought my printer and cartridges at their relais.Après update the printer (yet new ..) while perfectly fonctionné.Entre time I told the salesman my gait and sought reimbursement if the problem came from the cartridges, it had given me no problem. Everything is back to normal and I thank the seller's patience and cooperation, and if that happens, do not think this is necessarily a problem but see cartridges with Epson.
