Genuine OEM HP Deskjet 3070A e-All-in-One B611a Ink and Supplies
The HP Deskjet 3070A B611a uses separate HP 564 cartridges for black, cyan, magenta, and yellow. Since each color has its own position, you can deal with the ink that is low without changing the other three.
Toner Buzz carries genuine HP 564 individual colors, a three-color pack, and a 564XL high-yield black cartridge. Choose a single for one low color, or the color pack when cyan, magenta, and yellow are due around the same time.
