How do I bypass this general error?

I was just gifted an Epson Stylus NX415 hoping to use it at least as a scanner but when I power it on I get this error on the LCD display:

Error:

A printer error has occurred. Turn off the printer, then press On button to turn on. See your documentation.

I've checked the user guide and can't even find this status message listed in the documentation. When I try to power cycle the printer I get the same error. I've tried booting it with and without paper loaded.

When I have the OSX System Preferences panel open it lists the printer as on but idle:

And within the printer utility I get "General error," which is likely one of the least helpful error ever. Ha!

Is it a firmware issue? If so, does anyone know how to reset the printer to factory settings?

Cheers!
