Digital BW, The Print

My R2400 stopped printing. I went to Epson troubleshooting without
success. Power light is off, ink and paper lights flash rapidly in
sync. I can't find any paper blockage and the ink cart carrier seems
to move freely. I tried turning the printer and computer off and
disconnecting power to both for a few minutes, but did not solve the
problem. Anybody have any ideas?
