Chips, Printer Messages & Installation

Installing: open the front or side door, pull out the empty cartridge by its handle, then shake the new cartridge gently side to side five or six times. Remove the protective sheet, slide the cartridge into the matching color slot until it locks and close the door.

Supply messages: the printer may show a "non-genuine toner" or "toner not supported" notice. Press OK to keep printing. Turning off automatic firmware updates helps keep compatible chips working.

Streaks or faint print: shake the cartridge again and run the cleaning page or color registration from the printer menu. The imaging unit is separate on these printers and lasts much longer than the toner.

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, chip 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 Samsung CLT-K504S black print?

About 2,500 pages, based on Samsung's rating for the original CLT-K504S at roughly 5% coverage.

Can I replace one color at a time?

Yes. Each color is a separate cartridge.

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.
