Note:
The WorkForce 30 Series requires two black ink cartridges. If you install different sizes of black ink cartridges (one high capacity and one standard capacity) in the printer at the same time, the black ink level indicators in the printer software may show one black cartridge being used more quickly than the other. This is normal. Please note that the ink level indicators in the printer software are estimates only.
Windows: Double-click the

printer icon in the bottom right corner of your screen (the taskbar).
To disable checking for ink offers or updates from Epson, right-click the 
printer icon in the bottom right corner of your screen and select
Monitoring Preferences. Then click the checkbox at the bottom of the screen to deselect it.
