Epson printer not working?

All of my lights are flashing on my Epson Stylus Color 860 Printer. This includes the ink lights, paper jam light, and the on/off switch. I cannot get the lights to stop flashing nor manually cut it off. The only way I can cut off the printer is by holding down the on/off switch for a few seconds and releasing it. It does not turn off immediately but it does turns itself off after a few more minutes of flashing but when I turn it back on the flashing continues.
