Two-Pack Black Toner for HP 4000/4050

This two-pack of Laser Tek Services C4127X black toner cartridges is built for HP LaserJet 4000 and 4050 series printers. Each cartridge delivers an approximate yield of 10000 pages at five percent coverage. The compatible models include the 4000, 4000n, 4000se, 4000t, 4000tn, 4050, 4050n, 4050se, 4050t and 4050tn. Buyers receive two new aftermarket cartridges in a single package.

High-Volume Mono Printing on Legacy HP Lasers

The pack suits offices or home users who run high-volume monochrome jobs on the listed HP LaserJet 4000 or 4050 printers and want a lower cost per page than original supplies. It is not for colour printing, for any printer outside the named series, or for buyers who need a single cartridge rather than a twin pack. Users requiring manufacturer-branded consumables should look at original HP cartridges instead.

Verify Printer Model and Cartridge Code Before Order

Confirm that your printer model appears exactly in the compatible list: HP LaserJet 4000, 4000n, 4000se, 4000t, 4000tn, 4050, 4050n, 4050se, 4050t or 4050tn. Check that the cartridge code required by the device is C4127X or 27X. Ensure the printer is configured for standard-capacity black toner and that no firmware restriction blocks aftermarket supplies.

Questions about this item

Which printer models must I own for the C4127X cartridge to work?

The cartridge fits HP LaserJet 4000, 4000n, 4000se, 4000t, 4000tn, 4050, 4050n, 4050se, 4050t and 4050tn printers.

Will the 10000-page yield still be reached if I keep using an older LaserJet 4000 series printer?

Yield is rated at 5% coverage on the listed 4000 and 4050 models; actual pages depend on your print density and maintenance.

How can I verify the cartridge is printing correctly after installation?

Print a test page and check for crisp black text across the full page; consistent output from first to last page indicates proper operation.
