Compatible HP LaserJet 4000/4050 Series

This Laser Tek Services C4127X black toner cartridge replaces the HP 27X for LaserJet 4000, 4000n, 4000se, 4000t, 4000tn, 4050, 4050n, 4050se, 4050t and 4050tn printers. It is built for offices that need consistent monochrome output on these legacy workgroup devices. The single-pack format suits low-to-moderate volume environments.

Upgrade From Standard-Yield 27A Cartridge

The 27X high-yield design delivers approximately 10000 pages at five percent coverage, doubling the page count of the standard 27A cartridge. The jump is worth it when print runs regularly exceed a few thousand pages per month and reducing cartridge swaps matters. ISO 9001 and ISO 14001 factory standards back the build quality.

Verify Printer Model Before Ordering

Confirm your device appears in the compatible list above; other LaserJet models will not accept this cartridge. The unit is new and ships as a single black cartridge with no additional hardware. No driver updates or firmware changes are required for installation.
