Brother MFC-9335cdw Toner Cartridges
Your Brother MFC-9335cdw uses the TN-251, TN-255 toner cartridge series, and Ink Depot has been supplying these consumables since May 2016. This laser printer utilises a separate toner and drum system, separating the four CMYK cartridges from the imaging components. Because black text accounts for the vast majority of office output, the black toner is only available in standard yield, while the colour components offer standard or high-yield options. Business users frequently switch to high-yield colours to prevent uneven replacement patterns and minimise intervention intervals during multi-page print runs.
Real-world page output and lifecycle expectations
Brother calculates the page capacities for these cartridges using the ISO/IEC 19798 international standard for colour laser consumables. The black TN-251BK cartridge delivers 2,500 pages, while the matching TN-251 colour cartridges print 1,400 pages each. For heavier workloads, the TN-255 high-yield colour series extends individual outputs to 2,200 pages. Actual lifecycles depend directly on document coverage, so printing large graphical areas or background blocks will deplete the toner well before meeting these testing standards.
| Cartridge Number | Type | Colour | Page Yield | Cost Per Page |
|---|---|---|---|---|
| TN-251BK | Standard | Black | 2,500 | $0.068 |
| TN-251C | Standard | Cyan | 1,400 | $0.098 |
| TN-251M | Standard | Magenta | 1,400 | $0.098 |
| TN-251Y | Standard | Yellow | 1,400 | $0.098 |
| TN-255C | High Yield | Cyan | 2,200 | $0.081 |
| TN-255M | High Yield | Magenta | 2,200 | $0.081 |
| TN-255Y | High Yield | Yellow | 2,200 | $0.081 |
Cost Per Page = Total Cartridge Price ÷ Page Yield (at 5% coverage). Prices based on Genuine cartridges.
Managing multi-component lifecycles
Beyond standard toners, this four-colour laser system relies on a DR-251CL drum unit, a BU-220 belt unit, and a WT-220CL waste toner container. The drum holds an operating life of 15,000 pages, while the belt unit operates up to 50,000 pages before degradation occurs. Experience Tip: When installing a new drum unit, you must manually reset the internal page counter via the printer control panel menu, or the machine will continue to display a "Replace Drum" error and block operation.
Genuine vs compatible cartridges
The selection includes both original manufacturer products and third-party alternatives. Under Australian Consumer Law, using compatible cartridges does not void your printer warranty. This legal protection allows office managers to reduce operational overheads without jeopardising hardware coverage.

Stocking strategies and local delivery
For environments printing plain text reports, standard black toners provide the foundational footprint, while design-heavy documents require the high-yield TN-255 variants to prevent colour depletion mid-job. Opting for compatible options provides an additional layer of financial protection, as they carry a comprehensive money-back guarantee. All orders are fulfilled from our national infrastructure network with warehouses located in Sydney, Melbourne, Brisbane, Adelaide, and Perth. Free delivery applies on all orders over $99 (conditions apply). Explore our full catalogue of Brother toner cartridges to find your setup.
Pro Tip
Never replace the multi-pack drum unit prematurely when a single colour channel shows wear; individual drum frames can often be cleaned gently with a dry lint-free cloth to remove loose toner scatter and fix localized vertical lines.
Frequently Asked Questions
Why does my printer state the toner is empty when I just installed a high-yield TN-255 cartridge?
The physical gear mechanism on the side of TN-255 cartridges triggers an optical sensor inside the printer upon insertion. If the cartridge was inserted unevenly, or if it is a compatible version where the reset cog was slightly misaligned during assembly, the machine fails to register the new supply reservoir and requires a manual toner sensor override via the hidden maintenance menu on the LCD.
Can I mix a genuine Brother black toner with compatible TN-255 colour toners?
Yes, the machine architecture treats each colour slot as an isolated engine component, allowing you to run a genuine TN-251BK black cartridge alongside compatible cyan, magenta, and yellow cartridges without causing electronic conflicts or formulation blending issues.
How do I determine if my faded prints are caused by an exhausted TN-251 toner or a failing DR-251CL drum?
Toner exhaustion typically manifests as a gradual, uniform fading across the entire page or light vertical bands where the supply is low. A failing drum unit produces repeated, specific defects at precise geometric intervals—such as black dots, smudges, or thin horizontal lines—caused by physical scratches or electrical burns on the photosensitive roller surface.
