The HP 305XL High Yield Black Original Ink Cartridge (HP part 3YM62AE) is the genuine higher-capacity black cartridge for HP's compact DeskJet 2300/2700/4100-series and ENVY 6000/6400-series home inkjet printers. It uses pigment-based black ink for crisp, dark text on everyday documents, school work and forms, and the XL fill gives noticeably more pages than the standard HP 305 black, lowering the cost of each printed page for households and home offices. HP lists compatibility with the DeskJet 2300, 2700, 2700e, 2730, 2810e, 2820e, 2821e, 2822e, 2823e, 2825e, 2827e, 2842e, 4100, 4100e, 4134, 4210e, 4220e, 4222e, 4227e and 4230e, and the ENVY 6000e, 6010, 6020, 6022, 6030, 6032, 6400e, 6420, 6420e, 6422, 6430 and 6432. The packaged cartridge measures about 113 x 37 x 115 mm. Original HP cartridges carry HP's integrated printhead, so each replacement brings a fresh printhead and works with the printer's ink-level reporting.
