Purchased a new set of cartridges in December 2014 and have refilled 2x with excellent results. Refilled yesterday and the Printer Error message came -on instructions to off than on again. I have gone to several cycles (off/on), unplugged printer, reboot Mac, the message continues. Put in a set of Epson and printer starts fine.
Did i damaged the chip? There is no indication of which cartridge is the problem.
