Genuine OEM HP OfficeJet 4639 Ink and Supplies

For the HP OfficeJet 4639, HP 61XL black in a mixed pack means more pages from black, not higher-yield color as well. The black cartridge is paired with HP 61 standard tri-color, making the two capacities worth checking separately.

Toner Buzz carries genuine HP 61 packs for the 4639. Choose a standard black-and-color combination or the XL-black pairing for both inks, or the tri-color two-pack when your order is for color cartridges only.
