Frequently Asked Questions

Which toner does the Brother MFC-L6900DW use?
This multifunction printer uses TN3420 standard-yield or TN3440 high-yield black toner, plus the DR3425 drum unit.
What is the difference between toner and drum?
The toner cartridge holds the black printing powder, while the drum unit transfers the image onto the page. Toner is replaced regularly; the DR3425 drum lasts for a much higher page count.
Should I update the printer firmware?
Optional firmware updates from Brother may restrict the use of some compatible cartridges. If you plan to use compatible TN3420 or TN3440 toners, it is safest to avoid non-essential firmware updates.
Can I use compatible toner in my MFC-L6900DW?
Yes. Compatible TN3420 and TN3440 cartridges are available and can help reduce running costs, subject to firmware behaviour and your quality requirements.
Where do you ship from?
We ship from warehouses in Adelaide, Melbourne, Sydney, Brisbane and Perth for fast delivery across Australia.
