There is a reset routine that you can try. I don't have it with me right now. You can search for it on the internet or I know it has been posted on Dyesub.org. search for 1280 reset procedure. This is when the lights are blinking like a railroad crossing. green on red off, the red on green off etc.

A blinking red light can mean one of the ink cartridges is not seated correctly. Pull each one out, take a look at the contacts in the printer to make sure nothing is broken. Reseat each ink cartridge.

You can also go to epson.com troubleshooting page. They will have you enter which lights are blinking and what pattern they are blinking. It will tell you what they think is wrong.
