The HP 37X Black Toner Cartridge CF237X is an HP laser toner cartridge that handles the black text and graphics on every page printed by a compatible HP LaserJet Enterprise machine.Text stays sharp from the first page to the last because the toner formulation and the cartridge hardware are matched to the printer that uses them. The X suffix identifies the high yield version, so it holds more toner than the standard A cartridge and runs longer between changes.Fitting takes a moment: open the front access door, slide the spent cartridge out, and drop the replacement into the same slot. No tools are needed and no printer settings have to change. The cartridge carries the HP part number CF237X, so it can be matched against the printer's own supplies list before ordering.Suited to offices and home offices already running a compatible HP LaserJet Enterprise printer.
