How do I know when an ink cartridge needs to be replaced?
To find out which ink cartridge is low or empty, do one of the following:
1. Check the information in the EPSON Status Monitor 3 (Windows) or EPSON StatusMonitor (Macintosh) window that automatically appears on your screen when you print.
2. Press the Ink Cartridge Replacement button and check the flash pattern of the control panel lights: ERROR and POWER lights flash at the same speed = replace black cartridge ERROR light flashes twice as fast as the POWER light = replace color cartridge
