Xerox Phaser 8400 Compatible Black (6 Pack) 108R00608 Solid Ink Cartridges
DO NOT USE
WORST EVER. Worked great at first, but after printing out certificates for students the ink started to smear. Tried to run cleaning tool about 10 times, still smeared. Had to have tech support come out and take printer apart and clean.
