Epson Printer Won't Work

I updated my printer all the time but my printer won't work at all... It's in an error mode...

My printer is Epson XP-302-303-305-306 series.

What can I do now?
According to the manual, your printer displays an error code. Look that up in the manual and try to take the action it suggests.

You could also try including the error code in an Internet search for your printer. It might find someone who's managed to fix the problem.
