not refill them. The use of 
other products may affect 
your print quality and 
could result in printer 
damage.

based on images printed, 
print settings, paper type, 
frequency of use, and

quality, a small amount of 
ink remains in the 
cartridge after the

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.

use up a cartridge within 
six months of opening the 
package.

results. See the date printed on the package if 
unopened.
