Genuine OEM HP LaserJet 4000 Toners

The HP LaserJet 4000 uses HP 27A and high-yield HP 27X black toner, giving you two capacities for the printer's single toner position.

Toner Buzz carries genuine HP 27A and 27X singles, and HP 27X also comes in a two-pack. Choose one cartridge for the current need, or the two-pack when you want high-yield toner now and a second cartridge for later.
