Brother MFC-L9570CDW Toner Cartridges
Your Brother MFC-L9570CDW uses the BU-330CL / DR-441CL / TN-441 / TN-443 / TN-446 cartridge series. Ink Depot has been supplying premium replacement consumables for this colour laser printer since Sep 2017. The four-cartridge setup relies on independent toner delivery alongside separate heavy-duty components. Because offices operating this class of printer shift immense text workloads alongside presentations, managing individual colour depletion becomes critical. Purchasing bundle packs provides a streamlined way to handle predictable workplace print cycles while protecting your total running costs.
Expected page output and replacement cycles
High-volume office printing demands a clear understanding of how long these cartridges last in real use. The standard testing protocol for this class of laser toner is the ISO/IEC 19798 quality standard, which evaluates page yields by printing a continuous five-page suite representing average corporate layout coverage. Under daily operational conditions, text-heavy black invoices deplete differently from saturated marketing layouts. Keeping track of actual page coverage helps estimate exact ordering frequencies for your team.
| Cartridge Number | Type | Colour | Page Yield | Cost Per Page |
|---|---|---|---|---|
| TN-446BK | High Yield | Black | 6,500 | $0.029 |
| TN-446C | High Yield | Cyan | 6,500 | $0.066 |
| TN-446M | High Yield | Magenta | 6,500 | $0.066 |
| TN-446Y | High Yield | Yellow | 6,500 | $0.066 |
Cost Per Page = Total Cartridge Price ÷ Page Yield (at 5% coverage). Prices based on Genuine cartridges.
Genuine vs compatible cartridges
Operating expenses can be reduced considerably by evaluating third-party toner options. Under Australian Consumer Law, using compatible cartridges does not void your printer warranty. This legal protection means Australian businesses have the freedom to source high-capacity toner replacements without compromising the operational security of their office investment. You can read more about your consumer rights regarding third-party printer consumables in our comprehensive genuine vs compatible guide.
Long-life components and replacement tracking
Beyond the toner cartridges themselves, this printer depends on secondary wear items to preserve text clarity and crisp alignment. The DR-441CL drum unit acts as the physical imaging cylinder, transferring the dry toner powder onto the page, while the BU-330CL belt unit handles registration. Experience Tip: When replacing the DR-441CL drum unit, you must manually reset the internal page counter via the printer control panel menu to clear the replace drum warning message and maintain accurate life tracking.
Choosing the right cartridge setup
Workplaces primarily executing monochrome documents should focus on black toner replacements, whereas businesses using colour layouts or custom letterheads see balanced depletion across all four cartridges. Compatible alternatives provide an efficient fallback option to curb expenses, and they carry a full money-back guarantee to ensure complete financial peace of mind. All replacement orders over $99 (conditions apply) automatically qualify for free delivery. We dispatch directly from local regional distribution centres located in Sydney, Melbourne, Brisbane, Adelaide, and Perth to guarantee rapid delivery turnaround times for corporate workflows.

Pro Tip
Laser toners rely on physical moving gears inside the cartridge casing to meter out powder evenly; if your print volume drops temporarily, always gently rock the toner cartridge horizontally five or six times before installing to redistribute settled powder and prevent premature light printing.
Frequently Asked Questions
Can I run a standard black toner with high capacity colour toners in this system?
Yes, this printer operates independently with individual cartridge tracking, allowing you to mix and match standard or high-capacity toners like TN-446 based on your specific workplace usage patterns.
Why does the printer ask for a new DR-441CL drum unit when my toner cartridges are still full?
Toner cartridges hold the dry colour powder whereas the drum unit is the separate imaging cylinder that transfers that powder to the paper; they operate on entirely different lifecycles and wear out at separate intervals.
What causes faint print output across the page when my toner levels indicate they are adequate?
Faint or uneven text usually indicates that the internal corona wire on the drum unit requires cleaning; sliding the built-in green tab back and forth across the drum assembly several times clears baked-on toner dust and restores crisp text definition.
