Expected page output and replacement cycles
Page yields for monochrome Brother toner cartridges are measured using the industry-standard ISO/IEC 19752 testing standard based on 5% coverage per page. Actual output varies depending on graphic density, text coverage, and continuous versus job-based printing runs.
| Cartridge Number | Type | Colour | Page Yield | Cost Per Page |
|---|---|---|---|---|
| TN-3145 | Standard | Black | 3,500 | $0.050 |
| TN-3185 | High Yield | Black | 7,000 | $0.035 |
Cost Per Page = Total Cartridge Price ÷ Page Yield (at 5% coverage). Prices based on Genuine cartridges.
Choosing between genuine and compatible cartridges
Under Australian Consumer Law, using compatible cartridges does not void your printer warranty. Compatible options offer significant savings for office printing without sacrificing dark text clarity. Read our detailed guide on genuine and compatible cartridges to evaluate which standard best fits your print demand.
Managing the DR-3115 drum unit replacement
In this printing system, the toner cartridge and drum unit are distinct physical components. Experience Tip: The DR-3115 drum unit has a rated lifespan of 25,000 pages, meaning it typically outlasts three to seven standard toner cartridge replacements before needing to be renewed.
Selecting the best option for your office
If you print mainly text documents in high volumes, choosing compatible TN-3185 high-yield cartridges delivers substantial savings while keeping print quality sharp. All compatible options include a money-back guarantee for complete peace of mind. For full details on coverage, review our Returns policy.

Pro Tip
When replacing toner cartridges, ensure you do not confuse the toner cartridge with the DR-3115 drum unit; the toner snaps into the drum tray, so always replace only the specific component that has reached the end of its yield life.
Frequently Asked Questions
How do I know whether to replace the TN-3185 toner or the DR-3115 drum unit?
The printer displays separate notifications for toner exhaustion and drum wear. When toner runs out, replacing the TN-3185 cartridge restores black text printing without needing to replace the DR-3115 drum until its 25,000-page limit is reached.
Can I use the high-yield TN-3185 cartridge if my printer previously ran on standard TN-3145 toner?
Yes, both the TN-3145 standard cartridge and TN-3185 high-yield cartridge share identical physical dimensions and slot directly into the DR-3115 drum assembly.
Why does my printer still display a low drum message after installing a new TN-3185 toner cartridge?
Toner cartridges and drum units function independently. Installing a new TN-3185 toner cartridge replenishes the black powder supply, but if the DR-3115 drum has completed its rated 25,000-page cycle, it requires separate replacement to clear the drum warning.
