Compatible HP C4127A Toner Cartridge Black HP 27A Toner produce superior quality and consistency for a wide array of printing needs
HP C4127A Toner Cartridge Black HP 27A Toner 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:
Read the part number printed on the old cartridge's label. If it says C4127A, this is the matching reorder — the code on the cartridge itself is the dependable reference, because printer badges and series names cover several cartridge generations.
They are two names for one cartridge. HP markets the family as the 27A, while C4127A is the full part number of the black unit. Ordering by C4127A pins down the exact cartridge with no room for mix-ups.
Each C4127A is rated at 6,000 pages under standard coverage. An office printing mostly letters, invoices and reports works close to that assumption, so most buyers land near the rating before print starts to thin out.
Usually the cartridge. A band that fades along one edge means the toner inside is running low and distributing unevenly. Lift the cartridge out, rock it gently side to side to level what remains, and if the streak returns within a few dozen pages, the cartridge is finished.
Print one dense page of ordinary text. Characters should come out fully black from margin to margin with no gray wash behind them. A clean first page like that confirms the cartridge seated properly and is feeding evenly.
Reach our support team Monday–Friday, 9 AM–5 PM CST and describe what the first pages look like. The cartridge carries a 1-year warranty and 1-year free returns, and the shipping & returns page walks through how a return is handled.
This listing is organized around the code rather than any single printer badge: one C4127A black cartridge at $83.49, rated at 6,000 pages, for buyers who reorder straight from the label of the cartridge they just removed. The same unit serves the LaserJet 4000 and 4050 lines, so the code — not the badge on the machine — is what this page is built on.
Orders ship from whichever of our IL, PA, GA and CA warehouses sits closest to the delivery address. The wider HP range is here when the rest of the fleet needs attention too.
Considered the price and the print yield this is a very good buy. I don't use my printer for anything too formal so did not notice a difference between an original toner vs. this refilled one. Definitely would buy again.
Timely delivery. No problems installing once I realized i had to take a cover off. Worked on first try. Stay tuned for number of pages. Excellent packaging.
works great fit perfectly just as it should've.
Well-packaged and shipped quickly cartridge works great! I haven't printed much yet but printing is clear and concise. Many thanks!
Great value when price to performance is taken into account. It appears to work with quality on par with the factory unit. Works fine.
I can't tell any difference from a company brand so far. everything has worked as it should and only time and no. of copies will tell about the efficiency. the price was about half of the name brand so I am very happy with this product.
this product would be adequate for anyone with a home office . Copies are as clear as the original cartridge that came with the printer.

As far as I can see this cartridge is working fine and is compatible. I haven't used it long enough to judge all how many copies it will yield.
