Genuine OEM HP LaserJet P4015x Toners
With the LaserJet P4015x, the choice between HP 64A and 64X is about how often you change toner. Standard-yield 64A suits lighter printing, while high-yield 64X lasts for more pages. Maintenance kits service separate rollers and the fuser, which bonds toner to paper.
Toner Buzz offers genuine HP cartridges individually and a 64X two-pack for keeping another cartridge ready. The CB388A and CB389A maintenance kits are separate options for servicing the printer; match their 110-volt or 220-volt rating to your machine.
