Genuine OEM HP LaserJet Pro 400 Color M451dn Toners
The HP LaserJet Pro 400 Color M451dn uses HP 305A toner in black, cyan, magenta, and yellow. HP 305X gives you a high-yield black option, while the three color positions use HP 305A.
Toner Buzz carries genuine HP 305A and 305X singles, color and four-color sets, black two-packs, and a transfer belt. Choose a single for one low color, a set when several colors are due, or the belt only when the printer identifies that component.
