Compatible HP LaserJet 4050 Toner Cartridge Black produce superior quality and consistency for a wide array of printing needs
HP LaserJet 4050 Toner Cartridge Black is designed to deliver the best image quality and reliable printing. Toner cartridge is compatible with HP LaserJet 4000 4050 series printers and yields up to 6000 pages.
Features:
Yes. C4127A is the black cartridge of the HP 27A family, and it is the unit the LaserJet 4050 was built around. The label on the spent cartridge is the most reliable ordering reference there is.
They are. One C4127A design serves both the 4000 and 4050 lines, so listings that name either family are describing the same physical cartridge. The code, not the printer name in a listing title, is what identifies it.
The rating is 6,000 pages at standard coverage. Everyday office output — memos, letters, ledger pages — sits close to that coverage assumption, so the rating works as a fair planning figure for a 4050 in normal service.
It can be. As a cartridge empties, thin lines and small type lose density before big bold areas do. If the broken lines appear everywhere on the page rather than in one spot, a fresh cartridge is the likely fix.
A form or table the machine prints often. Familiar output makes differences obvious: lines should be unbroken, text fully black, and the sheet free of the grey wash that creeps in as a cartridge dies.
A 1-year warranty and 1-year free returns. Our support team answers Monday–Friday, 9 AM–5 PM CST, and the shipping & returns page describes how a return is handled.
This is the single-cartridge page for the base 4050: one C4127A in black at $83.49, rated at 6,000 pages. The 4050 followed the 4000 without changing the toner code, and this listing is written for owners who reorder by the label on the cartridge they just removed.
Orders ship from whichever of our IL, PA, GA and CA warehouses is closest to the destination. Larger packs and the broader HP selection are here when a busier period makes singles impractical.
