Genuine OEM HP OfficeJet 4635 Ink and Supplies

The HP OfficeJet 4635 uses HP 61 ink. When comparing mixed packs, look at whether black is standard HP 61 or higher-yield HP 61XL; both combinations pair black with an HP 61 standard tri-color cartridge.

Toner Buzz carries genuine HP 61 standard and mixed-capacity black-and-color packs for the 4635. For an order that only needs color, the HP 61 tri-color two-pack provides two standard color cartridges rather than increasing the capacity of one.
