Did you refill this ink cartridge? If the ink is low or out your printer will not print until the cartridge is reset. If you refill it yourself see http://www.ssclg.com/epsone.shtml. This is free software that will allow you to reset the ink levels. Then the red light will go out and poof you can print.

I had the same Problem and checked the solution:
This is a Printer Maintenance request.
Ink Overflow -
you sould change the waste ink pads under the printer mechanic.

Solution:

epson.com, actually you can print using black ink only, but you have to reset the color ink for it to register as full. :) or you can freeze the ink counter using the ssc service utility before the other ink rans out. :)

If you have carried out 4 to 5 head cleans, waited about 8 hours and done another 3 or head cleans doing nozzle checks after each clean (as recommended by the manual) and there is still no improvement then you will need a third party head cleaning solution such as this one:

Other makes & brands are available just google "inkjet head cleaning solution" Hope this helps.

Try this: First check which cartridge(s) are not being recognized. In my case where I replaced all three color cartridges, two were recognized right away but one was not. You find out by sending a print request to the printer and looking at the ink cartridge levels diagram in the dialog window. In my case two of three were fine but one had a red X on it. So I removed it and cleaned the contacts with alcohol then rocked it in the slot after pressing it in. It was recognized and the charging process began as normal.
