Ink and paper lights blinking alternately means that your internal “waste ink pads” are full and need resetting/cleaning out.
Check your Epson Status Monitor (on PC) for any error messages - if it says “service required” or “…end of service life” then it’s the waste pads.
You’ll need to reset the internal counter using WIC Reset tool (a reset key can be had very cheaply).
Then you’ll need to either:
a) clean or replace the internal pads (usually just a case of removing one or two screws on the recent Epsons)
b) extend a piece of tubing out of the printer and directing all waste ink to an external container, such as a bottle or tub.
