Compatible Black Toner Refill

This four-pack of black toner refill kits is built for HP LaserJet 4000, 4000n, 4000se, 4050 and 4050n printers using the HP C4127X 27X and C4127A 27A cartridges. It supplies the powder and instructions needed to refill an existing cartridge shell. The kit targets offices and home users who want to extend the life of their current hardware.

Suits cartridge reuse; not for new OEM buyers

The refill suits anyone prepared to open a spent cartridge and pour fresh toner, accepting the hands-on step to lower cost per page. It does not suit buyers who need a factory-sealed original cartridge with a fresh drum and developer roller already installed. Shops wanting a drop-in replacement without any user assembly should look at a complete compatible or OEM unit instead.

Refills HP 27X and 27A cartridges

The decisive specification is compatibility with the HP C4127X 27X and C4127A 27A cartridge models used in the LaserJet 4000 and 4050 series. If the printer takes those exact cartridge codes, the refill powder is formulated for that engine; if the printer uses a different cartridge number, this kit will not fit.

Questions about this item

Does the 4-pack include empty cartridges or only the black toner powder for refilling my HP 27X?

The kit supplies black toner refill material and instructions for use with your existing HP C4127X, 27X, C4127A or 27A cartridges; no empty cartridges are included.

Should I buy this 4-pack for both the standard 27A and high-yield 27X cartridges in my LaserJet 4000?

Yes, the refill material is compatible with both the HP 27A and 27X cartridges used in the LaserJet 4000, 4000n and 4000se models.

How many pages can I expect from one refill at the quoted 5% coverage on my LaserJet 4050?

Page yield depends on the specific cartridge capacity you are refilling — standard 27A or high-yield 27X — and on actual print coverage; the 5% figure is the industry test baseline, not a guaranteed page count.
