Genuine HP 27X cartridge for LaserJet 4000

This original HP toner cartridge is built for the LaserJet 4000 and 4050 printer families. It suits offices and workgroups that print regularly and want a single black cartridge that matches the printer’s specifications exactly.

ISO-rated 10,000-page yield at five percent coverage

The cartridge is rated for approximately 10,000 standard pages under the ISO/IEC 19752 test method. That figure helps you plan replacements and keeps the cost per page predictable for day-to-day printing.

UltraPrecise toner formulation for consistent output

HP’s UltraPrecise toner uses dual-polymer particles, a helical roller drive and magnetic seals to maintain print quality across the full yield. The design reduces the risk of streaks or fading during long print runs so the last page looks like the first.

Questions about this item

How do I install the HP C4127X cartridge in a LaserJet 4000, and which step do people often miss?

The declared yield of 10,000 pages at 5 % coverage per ISO/IEC 19752 is the first limit you will reach under sustained use.
