Brother MFC-J6740DW Ink Cartridges
Your Brother MFC-J6740DW uses the Brother LC432 and LC432XL ink cartridge series. Ink Depot has been supplying reliable consumables for this printer since Aug 2022.

Our 4.8 Google rating reflects a long-standing track record of premium cartridge performance.

Cartridge Pro Tip
Always replace low colour cartridges before starting large A3 print runs; A3 printing consumes substantially more ink per page than standard A4 documents, and running out mid-job can force complete page reprints.
Frequently Asked Questions
Can I mix standard LC432 and high-yield LC432XL cartridges in the Brother MFC-J6740DW?
Yes, standard LC432 and high-yield LC432XL cartridges share identical physical dimensions and electronic contacts. You can freely combine individual standard and XL cartridges across different colour slots based on your usage needs.
How does A3 paper size affect the page yield of LC432XL ink cartridges?
Standard ISO page yields for LC432XL cartridges (3,000 black, 1,500 colour) are calculated based on 5% ink coverage on A4 paper. Printing full-page A3 documents covers twice the surface area, which naturally depletes ink cartridges in roughly half the total printed page count.
Why does the Brother MFC-J6740DW use colour ink when printing mono documents?
Brother printers use small amounts of colour ink during periodic printhead maintenance and to enhance text sharpness on default print modes. Selecting "Greyscale" or "Mono Only" in your print driver settings forces the printer to rely exclusively on the LC432XLBK black cartridge.
