Expected page output and replacement cycles
Toner yield for standard TN-251 cartridges is measured at 2,500 pages for black and 1,400 pages for colour, while high-capacity TN-255 colour toners deliver 2,200 pages based on the ISO/IEC 19798 testing standard. Actual yield depends on coverage per document and print volume.

Choosing between genuine and compatible options
Opting for compatible TN-251 and TN-255 cartridges lowers ongoing printing expenses without risking printhead or internal component performance. Under Australian Consumer Law, using compatible cartridges does not void your printer warranty. To understand performance guarantees and quality standards, read our guide on genuine vs compatible cartridges.
Maintenance kits and imaging components
Separate drum units (DR-251CL) last around 15,000 pages and are separate from toner cartridges, meaning drums only require replacing after roughly six to seven toner changes.
Experience Tip: If your printer displays a "Replace Drum" message after fitting a new DR-251CL unit, you must manually reset the drum counter through the printer's touchscreen menu to clear the error.
Best way to stock these cartridges
If your office prints mostly text documents, stick with TN-251 black toners and keep high-yield TN-255 colour toners on standby for graphics and reports. Compatible options come with a full money-back guarantee for peace of mind. Free delivery applies on all orders over $99 (conditions apply), dispatched quickly from warehouse distribution centres located in Perth, Brisbane, Sydney, Melbourne, and Adelaide. Browse our complete range of Brother toner cartridges to suit your operational requirements, and check our returns policy for complete purchase confidence.
Pro Tip
Always replace the WT-220CL waste toner box when prompted before it reaches full capacity, as an overfilled waste box will stop the printer from operating to protect internal optical components.
Frequently Asked Questions
Can I install a high-yield TN-255 colour cartridge if my printer currently has a standard TN-251 cartridge?
Yes, high-yield TN-255 cyan, magenta, and yellow cartridges share identical physical outer dimensions with standard TN-251 colour cartridges and slot into the exact same drum housing assembly.
Do I need to replace all four drum units at the same time when the DR-251CL alert appears?
No, while the DR-251CL is often sold as a complete four-colour drum pack, individual drum slots can be replaced or cleared independently depending on wear, though replacing the full unit ensures even image density across all colours.
Why is my printer requesting a new drum unit when I just replaced the toner cartridge?
Brother laser printers keep toner supply and drum lifespan tracking entirely separate. The toner cartridge holds the powdered ink, while the DR-251CL drum unit transfers that image onto paper, requiring replacement on its own 15,000-page maintenance schedule.
