Genuine HP 27A black toner for LaserJet 4000

This cartridge is an original HP C4127A toner formulated for LaserJet 4000 and 4050 series printers. It delivers 6000 standard pages measured under ISO/IEC 19752. Offices needing reliable monochrome output on these models use this supply. Buyers with other printer families cannot use this cartridge.

Drop-in installation frees the printer

The cartridge installs directly into the printer without extra kits or adapters. Its Ultraprecise resolution technology works with the engine already in the LaserJet 4000 and 4050 series. No separate drum unit is required, so the supply chain stays simple. Shops that stock multiple toner types avoid cross-model confusion.

Sealed box protects shelf life until first use

The unit ships new in a factory-sealed box that guards the toner from humidity and light. One cartridge per box means no partial packs to manage. Inventory managers can store spares for extended periods without degradation. No software or firmware updates accompany this consumable.
