Brother HL-L2340DW Toner Cartridges
Your Brother HL-L2340DW uses the TN-2330 / TN-2350 cartridge series. Supplying replacement supplies for this mono laser setup since Sep 2014 has shown us how quickly busy office workflows burn through standard black capacity. Upgrading to high-yield TN-2350 cartridges significantly reduces routine swapouts during heavy print runs. Our 4.8 Google rating proves it: we consistently supply premium cartridges backed by rock-solid reliability.
Expected page output and replacement cycles
Monochrome laser page yields follow strict ISO/IEC 19752 testing standards based on 5% coverage per sheet. While the standard TN-2330 provides 1,200 printed pages, opting for the high-yield TN-2350 increases total output to 2,600 pages, cutting your cost per page down drastically for high-volume text printing.
| Cartridge Number | Type | Colour | Page Yield | Cost Per Page |
|---|---|---|---|---|
| TN-2330 | Standard | Black | 1,200 | $0.077 |
| TN-2350 | High Yield | Black | 2,600 | $0.060 |
Cost Per Page = Total Cartridge Price ÷ Page Yield (at 5% coverage). Prices based on Genuine cartridges.
How drum units work with these cartridges
This monochrome setup separates the toner container from the DR-2325 imaging drum unit, which holds an estimated lifespan of 12,000 pages. Experience Tip: If your printer continues showing a drum replacement message after a fresh drum installation, manual counter reset instructions must be triggered via the control panel while the front door stays unlatched.
What to know about compatible cartridges
Under Australian Consumer Law, using compatible cartridges does not void your printer warranty. Choosing third-party TN-2330 or TN-2350 consumables provides substantial budget savings without risking crisp, professional text output. Read our comprehensive genuine vs compatible guide to see how third-party toner measures up against original Brother cartridges.

Pro Tip
Never throw away your DR-2325 drum assembly when swapping an empty TN-2330 or TN-2350 cartridge; the toner cartridge clips directly inside the drum unit, which only needs replacing roughly once every four toner changes.
Frequently Asked Questions
Why does my printer display "Toner Low" immediately after inserting a new TN-2350 cartridge?
This typically happens if the internal reset gear on the toner cartridge failed to trigger the sensor arm inside the printer during insertion. Reinstalling the cartridge firmly into the DR-2325 drum housing usually forces the mechanism to recognise the full toner capacity.
Can I run a compatible TN-2350 cartridge inside a genuine Brother DR-2325 drum unit?
Yes, third-party TN-2330 and TN-2350 cartridges are built to match exact OEM physical specifications, snapping cleanly into original Brother DR-2325 drum units without causing fitment or contact issues.
What causes faint vertical lines down the page when toner levels are fine?
Vertical print defects in two-piece mono laser systems are generally caused by dust or loose toner settled on the drum unit's primary corona wire. Cleaning the wire by gently sliding the green tab across the DR-2325 drum housing back and forth clears up most line streaks.
