Query: Be warned

I purchased this printer in January. Since then Epson has sent me 5 replacement printers. 3 had clogged ink heads, one had a problem with communication between the computer and the printer and one had a scanner issue. They only send out refurbished printers if you have a problem. They finally decided to upgrade my printer to the CX6400, but neglected to send the ink, paper support and feeder guard. I called and they then sent the WRONG ink and no feeder guard. It has been very frustrating.
