Brother MFC-8510DN Toner Cartridges
Shop toner cartridges for your Brother MFC-8510DN, which uses the Brother TN-3310, TN-3340 and TN-3360 toner cartridge series along with DR-3325 drum assemblies. Ink Depot has been supplying reliable consumables for this printer since Sep 2012. The Brother MFC-8510DN is a high-speed monochrome laser multifunction printer engineered for demanding office document workflows. Switching from the standard TN-3310 black toner to high-yield TN-3340 cartridges reduces cost per page for high-volume text printing. Our 4.8 Google rating reflects a long-standing track record of premium cartridge performance.
Expected Page Output and Cartridge Life
Page yield calculations follow ISO/IEC 19752 standards for monochrome laser cartridges based on 5% page coverage. Actual page output varies based on document density, batch size, and line thickness during daily office printing.
| Cartridge Number | Type | Colour | Page Yield | Cost Per Page |
|---|---|---|---|---|
| TN-3310 | Standard | Black | 3,000 | $0.053 |
| TN-3340 | High Yield | Black | 8,000 | $0.035 |
Cost Per Page = Total Cartridge Price ÷ Page Yield (at 5% coverage). Prices based on Genuine cartridges.
DR-3325 Drum Assemblies and System Parts
The Brother MFC-8510DN uses a two-part print system where the toner cartridge and drum unit operate independently. While toner cartridges need replacing as ink powder depletes, the DR-3325 drum unit has a rated life of 30,000 pages and typically lasts through three to four high-yield TN-3340 toner changes before requiring replacement.
Choosing Between Genuine and Compatible Cartridges
Both genuine Brother and high-quality compatible TN-3340 toner cartridges are available for high-volume monochrome printing. Under Australian Consumer Law, using compatible cartridges does not void your printer warranty.

Cartridge Selection Advice
If you print more than 50 pages a week, always choose the TN-3340 high-yield toner over the standard TN-3310, as the cost per page drops significantly while quadrupling the interval between cartridge changes.
Frequently Asked Questions
What is the difference between the TN-3310 and TN-3340 toner cartridges?
The TN-3310 is a standard-yield black toner cartridge rated for approximately 3,000 pages, whereas the TN-3340 is a high-yield cartridge offering up to 8,000 pages. Both cartridges fit into the exact same drum housing and printer slot inside the Brother MFC-8510DN.
Does the DR-3325 drum unit come with toner included?
No, the DR-3325 is an independent imaging drum unit supplied without a toner cartridge. It holds the TN-3310 or TN-3340 toner cartridge and must be replaced separately every 30,000 pages.
Why is my printer showing 'Replace Toner' after installing a new TN-3340 cartridge?
This usually occurs if the toner cartridge gear or reset lever was not fully engaged when snapped into the DR-3325 drum assembly. Removing the drum and toner assembly, ensuring the cartridge clicks firmly into place, and reinstalling it clears the prompt.
