The HP 204A black toner cartridge, part number CF510A, is a genuine HP consumable for compatible HP Color LaserJet Pro printers that take the 204A code. Genuine cartridges are built to the tolerances the machine expects, so toner transfers evenly across the page and the printer's own counter reports a level you can plan around. Black is the toner that empties fastest on most machines, since it carries the text as well as the shadow detail in colour work.The cartridge slides into the printer's cartridge bay and is replaced as a single unit. Keep a spare on hand once the printer starts reporting low, because there is little warning between the first low toner message and pages that begin to fade at the edges.Specifications Model HP 204A Part number CF510A Colour Black Type Genuine HP toner cartridge Brand HP Compatibility Compatible HP Color LaserJet Pro printers that take the 204A code See the rest of the range in HP toner, or compare every brand we stock in toner cartridges.
