Chips, Printer Messages & Installation

Installing: open the top cover, slide out the drum unit and lift out the empty toner. Rock the new cartridge gently, remove the protective cover, and push it into the drum until it locks. Slide the corona wire tab back and forth a few times, then reinstall the drum and close the cover.

"Replace Toner" after a new cartridge: make sure the cartridge is fully clicked into the drum unit and the top cover is closed. The printer reads toner level with a sensor, so a seated cartridge clears the message.

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 Brother TN433 cyan print?

About 4,000 pages, based on Brother's rating for the original TN433C 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.
