Print cartridge combinations
For printing most documents, use the tri-color print cartridge and the black print
cartridge. When printing photos, you can use either the photo print cartridge or the
gray photo print cartridge along with the tri-color print cartridge cradle.
Always install the tri-color print cartridge in the
left
print cartridge cradle
compartment.
Install the black, photo, or gray photo print cartridge in the
right
print cartridge cradle
compartment.
