Install print cartridges
When you need to replace print cartridges, make sure you have the correct print
cartridges for the printer, and then install them in the print cartridge cradle.
Print cartridge combinations
For printing most documents, use the tri-color print cartridge and the black print cartridge.
When printing photos, use the
photo print cartridge along with the tri-color print cartridge.

cartridge in conjunction with the tri-color print cartridge.

of the print cartridge cradle.
