Epson PM260 printing greenish

Any ideas on what to do?? Should I buy a REAL epson cartridge or do you think this PM260 is shot due to LD products? If I just use the card and no computer it still is greenish. So it seems like it is the cartridge. I used their new cartridge for 12 prints then this happened, they sent me another and the same is happening?? Do you think its permanently busted!!! heads are aligned heads/nozzle check is fine???
