Brother MFC-J6520DW Ink Cartridges
Your Brother MFC-J6520DW uses the LC131 / LC133 / LC135XL / LC137XL / LC139XL ink cartridge series. Ink Depot has been supplying consumables for this printer since Feb 2014, supporting its high-volume small business operational demands. The four-cartridge individual ink system ensures efficient document management by avoiding single-cartridge tri-colour waste. Offices utilizing this workspace printer typically transition permanently to high-yield black cartridges to match heavy daily text outputs while maintaining predictable colour replacement intervals.
Document Production and High-Yield Lifecycles
Small office setups rely on consistent operational continuity, which makes understanding expected page output and replacement cycles critical. The high-capacity LC139XL black cartridge is engineered to produce significantly more pages than the LC135XL colour variants, creating a staggered replacement cycle where monochrome consumables are swapped out twice as often as individual colours. Brother calculates these capacities based on the international ISO/IEC 24711 standard for inkjet systems, which utilizes standardised text documents printed continuously. Real-world business printing with dense legal text, logos, or complex charts will naturally accelerate ink consumption compared to these laboratory baselines.
| Cartridge Number | Type | Colour | Page Yield | Cost Per Page |
|---|---|---|---|---|
| LC135XL-C | High Yield | Cyan | 1,200 | $0.035 |
| LC135XL-M | High Yield | Magenta | 1,200 | $0.035 |
| LC135XL-Y | High Yield | Yellow | 1,200 | $0.035 |
| LC139XL-BK | Extra High Yield | Black | 2,400 | $0.027 |
Cost Per Page = Total Cartridge Price ÷ Page Yield (at 5% coverage). Prices based on Genuine cartridges.
Choosing Between Genuine and Compatible Options
Sourcing replacement inks requires balancing corporate budgeting against standard operational performance. Third-party compatible cartridges offer a stark reduction in operating expenses, dropping running costs to fractions of a cent per page. Under Australian Consumer Law, using compatible cartridges does not void your printer warranty. This legal protection guarantees that your office can alternate between original manufacturer options and premium compatible items without forfeiting hardware security. Every compatible ink supplied by Ink Depot features a full money-back guarantee if it fails to perform to your expectations. You can learn more about how third-party alternatives interact with your device by reading our genuine vs compatible cartridges guide.
Procurement Framework and Delivery Management
Managing office inventory effectively depends on specific document production habits. Offices managing extensive accounting documentation or report printing should prioritise multipacks and standalone high-capacity black cartridges. For diverse office workgroups requiring frequent presentation prints, purchasing a combined value bundle pack prevents sudden workflow interruptions. Free delivery applies on all orders over $99 (conditions apply), dispatched daily from our national warehousing infrastructure across Perth, Brisbane, Sydney, Melbourne, and Adelaide to ensure minimized downtime. Returns or physical item queries are processed under our comprehensive online Returns policy, while additional printer supplies can be found through our dedicated Brother ink cartridges portal.
Pro Tip
Always keep a spare high-capacity black cartridge in storage, because small business printers often lock out printing functions entirely once the black ink is completely exhausted, regardless of how much colour remains in the individual cyan, magenta, or yellow slots.
Frequently Asked Questions
Can I install an LC139XL black cartridge if my printer previously used standard LC133 inks?
Yes, high-yield LC139XL cartridges are designed with the identical physical locking mechanisms and slot tracks as their standard capacity counterparts, meaning they fit seamlessly into the same cartridge carriage while carrying a larger physical ink reservoir inside.
Why does my printer show reduced ink levels in colour cartridges even though I primarily print black text?
The individual ink delivery system performs microscopic printhead cleaning and priming maintenance cycles during startup and shutdown to prevent nozzle clogging. This automatic hardware maintenance consumes small volumes of cyan, magenta, and yellow ink regardless of your document colour settings.
How do bundle packs lower the overall running costs for this printer model?
Bundles group the individual high-yield black and colour components together at a reduced base price compared to purchasing single cartridges separately, dropping the combined cost-per-page baseline and maximizing the financial return on high-volume print runs.
