Brother MFC-J4540DW Ink Cartridges
Your Brother MFC-J4540DW uses the LC436 / LC436XL ink cartridge series, a high-yield system designed for the demanding workloads of small business environments. We have been supplying reliable consumables for this printer since May 2021, supporting its four-cartridge configuration. Because this printer is built for volume, users typically find the black cartridge depletes much faster due to heavy document printing. Transitioning to the XL series for both black and colour is the standard behaviour for those looking to minimise maintenance and maintain print continuity.
Understanding page output and replacement cycles
The Brother LC436 series is rated using the ISO/IEC 24711 standard, which provides a reliable baseline for document printing. While standard LC436 cartridges offer a solid starting point, the LC436XL variants are engineered for high-volume environments, significantly extending the time between replacements. In a typical office setting, the black ink (BK) usually reaches its yield limit well before the colours, especially if printing internal drafts or invoices. However, for marketing materials or presentations, the 5,000-page XL colour capacity ensures the printer remains operational without the constant "low ink" interruptions common with smaller inkjet systems.

Genuine vs compatible cartridges
This printer supports both genuine Brother consumables and high-quality compatible alternatives. Our compatible LC436XL cartridges provide a cost-effective way to manage office overheads without sacrificing reliability. Under Australian Consumer Law, using compatible cartridges does not void your printer warranty. For those interested in the differences in manufacturing and performance, you can read more about genuine vs compatible cartridges to make an informed decision for your workplace.
Stocking strategies and delivery
For small businesses, the most efficient way to manage this printer is by stocking the high-yield LC436XL bundle packs. These bundles ensure you have a full set of colours on hand when the inevitable "out of ink" prompt appears. If you mainly print text-heavy documents, we recommend keeping an extra black XL cartridge in the cupboard. Our compatible cartridges come with a money-back guarantee if they do not meet your expectations. You can view our returns policy for full details. Free delivery applies on all orders over $99 (conditions apply), and we ship directly from our national network of warehouses in Perth, Brisbane, Sydney, Melbourne, and Adelaide.

Pro Tip
Always keep the printer connected to power rather than turning it off at the wall. The MFC-J4540DW performs micro-cleaning cycles to prevent the high-yield LC436 nozzles from clogging; cutting power completely can force a more intensive (and ink-heavy) cleaning cycle next time you boot up.
Frequently Asked Questions
Can I mix a genuine Brother black cartridge with compatible LC436XL colours?
Yes, the printer's internal sensors treat each slot independently. You can use a mix of genuine and compatible cartridges across the four slots without causing any communication errors or print quality conflicts.
How does the printer handle printing when one colour LC436XL cartridge is empty?
Like most modern office inkjets, the MFC-J4540DW generally requires all cartridges to have a minimum level of ink to function. This is to protect the permanent printhead from heat damage that occurs when "firing" empty nozzles.
Why is the yield for the LC436XL Black different from the XL Colours?
The black cartridge (LC436XLBK) contains a higher volume of pigment-based ink compared to the dye-based colours, as it is designed for the high-density requirements of text documents. This allows for approximately 6,000 pages of text versus 5,000 pages for the colours.
