Note: We recommend 
that you use genuine 
Epson cartridges and do 
not refill them. The use of 
other products may affect 
your print quality and 
could result in printer 
damage.
Yields vary considerably 
based on images printed, 
print settings, paper type, 
frequency of use, and 
temperature. For print 
quality, a small amount of 
ink remains in the 
cartridge after the 
“replace cartridge” 
indicator comes on. The 
printer ships with full 
cartridges and part of the 
ink from this first set of 
cartridges is used for 
priming the printer.
For best printing results, 
use up a cartridge within 
six months of opening the 
package.
Cartridge life2 years from production date if unopened; 
within 6 months after opening package
