Chips, Printer Messages & Installation

Installing: open the front cover and lift out the drum unit with the toner attached. Push down the green lock lever to release the empty toner from the DR331CL drum, then rock the new toner gently side to side and remove its protective cover. Click it into the drum until the lever lifts, slide the corona wire tab back and forth a few times to clean it, and reinstall the assembly.

"Replace Toner" after a new cartridge: make sure the cartridge is fully clicked into the drum and the cover is closed. Brother printers read toner level with a sensor, so a firmly seated cartridge clears the message.

Toner vs. drum: this is the toner only. The DR331CL drum is a separate part that lasts through several toner cartridges; replace it when the printer shows "Replace Drum" or prints get spotty.

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 TN339 magenta print?

About 6,000 pages, based on Brother's rating for the original TN339M 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.
