Brother MFC-J825DW Ink Cartridges
Your Brother MFC-J825DW uses the Brother LC40 / LC73 ink cartridge series. Ink Depot has been supplying reliable ink cartridges for this A4 wireless multi-function printer with direct disc printing capabilities since Nov 2011. Standard LC40 cartridges suit light everyday output, whereas upgrading to high-yield LC73BK black and LC73 colour inks delivers lower per-page printing costs for busy home office environments. Our 4.8 Google rating reflects a long-standing track record of premium cartridge performance.
How long these cartridges last in real use
Page yields for LC40 and LC73 cartridges are determined using the ISO/IEC 24711 standard for inkjet printing. Standard LC40 tanks output up to 300 pages, while high-yield LC73 cartridges double that capacity to support frequent home office printing without constant replacements.

Genuine vs compatible cartridges
Choosing between genuine Brother inks and compatible alternatives depends on your budget and output volume. Compatible LC73 cartridges provide substantial savings without compromising text clarity or colour vibrance, making them popular for high-volume printing. Under Australian Consumer Law, using compatible cartridges does not void your printer warranty. Learn more about how third-party options compare in our detailed guide on genuine vs compatible cartridges.
Selecting the right cartridge setup
For regular black text documents, purchasing high-yield LC73BK single cartridges or multipacks provides the best overall economy. All compatible cartridges come backed by a 90-day money-back guarantee for complete peace of mind. We stock a full range of genuine and compatible Brother ink cartridges dispatched quickly from our warehouses in Perth, Brisbane, Sydney, Melbourne and Adelaide. Free delivery applies on all orders over $99. Refer to our returns policy for full coverage details.
Pro Tip
If you primarily print monochrome text, you do not need to replace empty colour cartridges immediately to keep printing basic black pages, provided you enable the temporary black-and-white print mode on your desktop settings before the black tank runs dry.
Frequently Asked Questions
Can I mix LC40 standard cartridges and LC73 high-yield cartridges in the same printer?
Yes. The Brother MFC-J825DW accepts any mix of standard LC40 and high-yield LC73 cartridges simultaneously across all four colour slots because both cartridge sizes share identical physical exterior dimensions.
Why does the colour ink deplete even when printing mostly black documents?
The MFC-J825DW performs periodic automatic maintenance routines to keep printhead nozzles clear and prevent dried ink blockages. A tiny amount of cyan, magenta, and yellow ink is consumed during these self-cleaning cycles, even if your document settings are set to greyscale.
How does replacing individual ink cartridges benefit overall running costs?
Unlike integrated multi-colour tanks, the four-cartridge system lets you replace individual colours as they run out. If you print heavy blue logos, you only replace the LC73C cyan cartridge without throwing away remaining magenta or yellow ink.
