Frequently Asked Questions

Which toner does the Brother HL-L6400DW use?
The HL-L6400DW uses TN3420 standard-yield or TN3440 high-yield black toner cartridges, along with the DR3425 drum unit.
What is the difference between toner and drum?
The toner cartridge holds the black powder used to create your printed text and images. The drum unit transfers that image onto the page. Toner is replaced more frequently, while the DR3425 drum lasts for a much higher page count.
Should I update the printer firmware?
Optional firmware updates from Brother may block some compatible toner cartridges. If you plan to use compatible TN3420 or TN3440 cartridges, we recommend avoiding non-essential firmware updates.
Can I use compatible toner in my HL-L6400DW?
Yes. Compatible TN3420 and TN3440 cartridges are available for the HL-L6400DW and can help reduce printing costs, depending on firmware behaviour and your print quality requirements.
Where do you ship from?
We ship from warehouses in Adelaide, Melbourne, Sydney, Brisbane and Perth. Orders are dispatched quickly from the nearest warehouse for fast delivery across Australia.
