Our office needs a HP LaserJet CP4005n Black printer cartridge 642A What black ink cartridge will work in this printer

Asked by: Bethel Leg Office
Thank you for your question! The HP LaserJet CP4005n is an older printer. The toner cartridges for this printer are no longer available from HP. The compatible toner is the HP 642A. You may be able to locate these cartridges from one of our retail partner websites.
