I just updated firmware on my XP-630 and it no longer recognizes my non-Epson ink cartridges. I asked Epson how to go back to my former firmware and was told that it wasn't possible. Their solution is to install Epson cartridges. My remanufactured cartridges had been working flawlessly until the update. If anyone knows how to go back to the last firmware, I would appreciate some help.
