Choosing Between Genuine and Compatible Toners
Under Australian Consumer Law, using compatible cartridges does not void your printer warranty. Choosing compatible TN-3440 or TN-3470 toners allows busy workplaces to lower routine office expense without compromising clear text output. Read our comprehensive genuine vs compatible cartridge guide to evaluate the ideal choice for your operational environment.
Brother DR-3425 Drum Unit Lifecycle
The DR-3425 drum unit is an independent consumable responsible for transferring toner onto paper, rated for up to 50,000 pages. Experience Tip: The DR-3425 drum unit outlasts multiple toner replacements, so you only need to swap the drum when the printer explicitly prompts for a new imaging component.
Cartridge Options and Fast Delivery
For routine text documents, high-yield TN-3440 or super high-yield TN-3470 options deliver substantial savings per page compared to standard TN-3420 cartridges. If you opt for compatible toners to cut expenses, every cartridge is backed by a full money-back guarantee under our returns policy. We dispatch directly from local warehouses across Sydney, Melbourne, Brisbane, Adelaide, and Perth to ensure quick turnaround times. Free delivery applies on all orders over $99.

Pro Tip for Brother HL-L6400DW Owners
Always check whether your current printing bottleneck is caused by depleted toner or an exhausted drum unit before ordering, as replacing the super high-yield TN-3470 toner cartridge won't reset the 50,000-page counter on an end-of-life DR-3425 drum.
Frequently Asked Questions
What is the difference between TN-3420, TN-3440, and TN-3470 toner cartridges?
These cartridges differ in toner capacity and page output while sharing identical physical installation slots. Standard TN-3420 provides approximately 3,000 pages, TN-3440 high-yield provides 8,000 pages, and TN-3470 super high-yield delivers up to 12,000 pages, making TN-3470 the most economical choice for heavy printing.
Do I need to replace the DR-3425 drum unit every time I replace the TN-3470 toner?
No, the drum unit and toner cartridge operate as separate components. The DR-3425 drum lasts up to 50,000 pages, meaning it usually outlasts four to six super high-yield TN-3470 toner cartridges before requiring replacement.
Can I install a super high-yield TN-3470 toner cartridge into standard HL-L6400DW tray setups?
Yes, the super high-yield TN-3470 cartridge fits directly into the same DR-3425 drum cradle as standard TN-3420 and TN-3440 toners without requiring any adapter or tray modification.
