The HP Color LaserJet 2820 uses compatible toner in four colors: black Q3960A (about 5,000 pages), plus cyan Q3961A, magenta Q3963A and yellow Q3962A (about 4,000 pages each). All four are also called 122A. A compatible Q3964A drum, rated at about 20,000 pages, fits the same printer. The same supplies also work with the Color LaserJet 2830, Color LaserJet 2840 and Color LaserJet 2550n. Orders get same-day shipping on most orders.
