It appears that your printer's ink counter detected that the ink level on your ink cartridge has run out.
This error usually occurs if one of the ink cartridges run out of ink and have been refilled.
You will have to reset your printer. There are two possible ways to reset it.
1. Use a universal chip resetter to reset the smart chips on your ink cartridges. You will have to order this online.. http://www.1800savemart.com/epsonresetter.html
