We have been supplying premium consumables for this printer since Jul 2013, ensuring workplace teams maintain uninterrupted document production.

Choosing between genuine and compatible options
Under Australian Consumer Law, using compatible cartridges does not void your printer warranty. This means businesses can significantly reduce overheads without compromising their legal protections. For a detailed breakdown of the differences in formulation and performance, you can read our comprehensive genuine vs compatible cartridges guide.
Managing independent printer parts
Beyond standard toner housings, this printer relies on three separate mechanical components to maintain crisp text and graphics: the DR-251CL drum unit, the WT-220CL waste toner bottle, and the BU-220 transfer belt unit. Experience Tip: When installing a new drum unit, remember to manually reset the drum counter via the printer control panel to clear the replace drum warning message.
Best way to stock these cartridges
If you print mainly text documents with occasional corporate logos, prioritising high-yield black toner alongside high-yield colour options creates the most stable maintenance routine. For users seeking maximum value, choosing compatible cartridges provides an excellent alternative backed by a complete money back guarantee if they do not perform perfectly. Free delivery applies on all orders over $99 (conditions apply), and all orders are dispatched directly from our national fulfilment network with regional warehouses located across Perth, Brisbane, Sydney, Melbourne, and Adelaide. You can quickly explore the broader selection of Brother toner cartridges to suit your workspace setups.
Pro Tip
Always check whether you need a standard or high-yield colour cartridge before ordering, as the high-yield TN-255 series offers nearly double the document print capacity for a much lower cost per page.
Frequently Asked Questions
Do I need to replace the DR-251CL drum unit every time I change the toner cartridge?
No, the drum unit has a much longer operational lifespan of up to 15,000 pages, meaning it generally lasts through several toner replacement cycles before needing to be completely swapped out.
Can I mix a genuine Brother black toner cartridge with compatible colour cartridges?
Yes, the printer handles mixed setups perfectly, allowing you to combine genuine and compatible toner cartridges across the four slots without encountering any software communication issues.
What happens if the WT-220CL waste toner bottle fills up mid-job?
The printer will halt all printing operations immediately until the waste toner bottle is replaced, which is why keeping a spare unit on hand is recommended for office environments that produce complex graphical layouts.
