Compatible Toner TN-2421 for Brother (TN2421) (Black)

Toner cartridges bearing the DrTusz logo are made from high-quality, specially selected, and tested components available on the market. They ensure high print quality, comparable to that achieved with original toner cartridges.

Toner replacements offer real savings; they are significantly cheaper than originals and often have a higher capacity, allowing you to print more pages from a single cartridge. High-quality compatible toners deliver crisp, long-lasting prints and work seamlessly with your printer, so you pay less without compromising on the final result.

Additionally, our compatible toner cartridges are covered by the “Gold Warranty” program, which provides coverage for the entire lifespan of the cartridge. Its key advantage is a quick, hassle-free, and effective claims process.

Our online store does not buy back empty cartridges . We only offer free disposal of products that were previously purchased from our store.

Used ink and toner cartridges are hazardous waste and must not be disposed of in regular trash bins—that’s why we offer free disposal so you can help protect the environment in a simple and safe way. For larger quantities of empty cartridges (10 or more), we’ll arrange for pickup by a courier after you contact us via email; for smaller quantities, you can return them to us at your own expense or bring them in person to our brick-and-mortar store. Companies and public entities can also obtain a Waste Transfer Form (downloadable from the BDO system) if they generate more than 100 kg of such waste annually.

To compare printing costs, check the price of a replacement ink or toner cartridge for your printer, and then calculate the cost per page by dividing the price of the cartridge by its yield, expressed in the number of pages.

It’s worth noting that the stated yield is determined in accordance with ISO standards, which influence how the number of pages is measured.
