Installing a print cartridge
1
If you are installing a new cartridge, remove the sticker and
transparent tape from the back and bottom of the cartridge.
Note: If only a color cartridge is shipped with your All-In-One,
install a black print cartridge for optimum print quality.
Warning:
Do not touch the gold contact area on the cartridges.
2
Insert the color cartridge in the left carrier.
Insert the black cartridge in the right carrier.
Note: To extend the life of your color cartridge and improve
printing speed, install a black cartridge along with the
color cartridge.
