Excelent cartridge
This is the second time I've ordered this compatible toner cartridge; no streaks no ugly dot -- printing is perfect and at less than a third the cost of the HP product.

Good toner and work perfect
This is the second time I've ordered this product. Each cartridge arrived clean no problems with the packaging as some have reported.
-
Great price and works perfectly!
It was very easy to install this cartridge and it produces cleanly printed sheets. Far cheaper than the name brand...will purchase again!
-
So far so good.
Thought at first it didn't fit my printer then realized that there was a cover on top of it which makes it not fit my printer. so far so good.

Frequently Asked Questions
How do I confirm this is the black cartridge my printer takes?
Check the number on the cartridge you are pulling out. If it reads C9720A — the black member of the HP 641A family — this is its compatible replacement. The part number is printed on our box as well, so you can match the two before you open anything, and this single cartridge is priced at $65.10.
How many pages should I expect from it?
The C9720A is rated at about 9,000 pages at standard coverage. A text-heavy office — memos, invoices, reports — lives close to that rating, while pages carrying large graphics or solid fills spend toner faster and finish sooner.
Is this the right cartridge for a Color LaserJet 4600?
Yes. This black serves the Color LaserJet 4600 series and its siblings in the 4600/4650 line. If your machine's supply screen names the 641A family, the C9720A is the black position in that family.
My black text looks gray and washed out. Is the cartridge finished?
Usually, yes. Even, pale text across the whole page is the classic end-of-life sign for a black cartridge. Take it out and rock it gently side to side a few times — that redistributes the remaining toner and often buys a short run of acceptable pages while the replacement is on its way.
Can I swap it while the printer is mid-job?
Wait for the job to finish or pause it first. Open the front cover, pull the black cartridge straight out by its handle, and slide the new one in until it seats. The printer recalibrates briefly and is ready again; a test page confirms the density is back.
What protection comes with this cartridge?
Every cartridge we sell under the HP compatible range carries a 1-year warranty and 1-year free returns. Orders ship from our warehouses in IL, PA, GA and CA, and our support team is available Monday–Friday, 9 AM–5 PM CST if a cartridge misbehaves.
About This C9720A Black Cartridge
Some printers earn their keep on black alone, and this is the cartridge for them. The C9720A puts a rated 9,000 pages of dense, even black into the 4600-family machines that still anchor plenty of offices, at $65.10 for the single cartridge. Ordering more than one? See our shipping and returns page for how multi-item orders travel and what the return window covers.
