If you need to change a cartridge before it or any other cartridges are low or expended, run the Ink Cartridge Replacement utility.

You cannot print or copy when an ink cartridge is expended even if the other cartridges are not expended. Replace any expended cartridges before printing or copying.

Leave your old cartridges in the Epson Stylus NX110 Series until you are ready to replace them to prevent the print head nozzles from drying out.
When an installed ink cartridge is more than six months old, you may need to replace it if your printouts do not look their best, even after cleaning and aligning the print head.
Follow the instructions in these sections to check and replace your ink cartridges:
Replace Cartridges Using a Printer Software Utility
For best printing results, use up a cartridge within six months of opening the package. If you need to replace a cartridge when the ink light is flashing or off (before the cartridge is expended), you can run the Ink Cartridge Replacement utility.

1. Windows: Right-click the printer icon in the bottom right corner of your screen (the taskbar) and select Printer Settings. Click the Maintenance tab.
Macintosh: Open the Applications folder, open EPSON Printer Utility3, select your printer (if necessary), and click OK.

You see one of these screen SEE ATTACHMENT BELOW

2. Click the Ink Cartridge Replacement utility icon and follow the on-screen instructions to replace your ink cartridges as necessary

Usually when this happens the printer fails to goes through the motions of the printing process, kind of stands still with indicator lights just blinking away. This could be as a result of either of these scenarios.
i.                     Ink cartridge has developed incompatibility or is incompatible
The Solution is to try an older/another cartridge (doesn’t matter if ink is finished. You must replace cartridge one at a time). If lights stop blinking it confirms that your cartridge has become incompatible or developed incompatibility. Also if your printer is the type that can work with only one cartridge, remove one after the other (closing back the lid/cover) to determine which in the set (black or color) has become incompatible. At the instance the incompatible one is removed and you close the lid, the blinking will stop (for printers that can print with one ink cartridge only). Just replace the incompatible one and start printing again. In most cases the issue is always with one cartridge. But if both are affected, you have to replace both. Because of this type of problem, always keep used cartridges somewhere safe; they come in handy for this type of troubleshooting.
ii.                   The Cartridge electronic panel  is dirty
The electronic panel on the cartridge that makes contact with the cartridge carrier inside the printer is dirty and needs cleaning.  This electronic panel is front part of the cartridge with copper “dots”.
The Solution is to try to clean this panel with a piece of folded tissue paper soaked in a bit of methylated spirit. Also try to clean the area in the cartridge carrier/holder that makes contact with the cartridge’s electronic panel (Usually this is more difficult). If you cannot reach it with your fingers, use a stick or something with tissue wrapped around it. Allow to dry well and return the cartridges, close the cover. The blinking should stop if the electronic panel is the issue. Once the blinking stops the printer will print.
