Supply messages: if the printer shows a "non-HP supply" or "used supply" notice, press OK or Continue to keep printing. If the cartridge isn't recognized, check that all packing material is off and reseat it firmly.

Streaks or faint print: rock the cartridge again to redistribute toner and print a cleaning page from the printer menu. See laser printer streaks and lines.

Compatible vs. Remanufactured vs. Original

Original (OEM) toner is new from the printer brand and costs the most. Compatible toner, like this cartridge, is newly manufactured by a third party to the original's size and page-yield specifications, so it drops into the same slot at a much lower price. Remanufactured toner is an emptied original cartridge that has been rebuilt and refilled. Castle Ink sells compatible (newly manufactured) toner and remanufactured inkjet cartridges.

Frequently Asked Questions

How many pages does the HP C4149A black print?

About 17,000 pages, based on HP's rating for the original C4149A at roughly 5% coverage.

Can I replace one color at a time?

Yes. Each color is a separate cartridge, so replace only the one that is empty.

Will this void my printer warranty?

No. Under the U.S. Magnuson-Moss Warranty Act, a manufacturer can't void your printer warranty just because you used a third-party or remanufactured supply. If a non-original supply directly caused damage, that specific repair might not be covered.

How long can I store it?

Sealed toner keeps for about two years at room temperature. Keep it in its bag, away from heat and direct sunlight, and store it flat.

When will my order ship?

Orders placed by 4 PM ET, Monday through Friday, ship the same business day from Long Island, NY, by USPS (2–5 business days). Expedited 1–2 day delivery is available at checkout, and shipping is free on orders over $50.
