Replacing Ink Cartridges
Before you begin a large print job, you should check your ink levels. If one of 
your cartridges is low, you can replace it before you start. Or you can wait 
until the ink is expended, replace the cartridge, and then continue the job 
without any loss of print quality. However, it is best to replace a low ink 
cartridge before starting a large print job.
The easiest way to check ink levels is from the control panel LCD screen. 
The numbers above the ink icons on the LCD screen correspond to the 
9 ink cartridge slots on the printer.
The icons show the approximate amount of ink remaining.
Tip: You can store 
partially used ink 
cartridges for up to 
6 months. If you do so, 
Epson recommends 
covering the openings 
with tape.
