Brother MFC-7340 Toner Cartridges
Your Brother MFC-7340 uses the TN-2130, TN-2150 cartridge series consisting of a separate toner and drum unit setup. Ink Depot has been supplying consumables for this monochrome laser printer since Jun 2026. Small business environments typically scale up to the high-yield TN-2150 toner to match heavy document print cycles. Our 4.8 Google rating reflects a long-standing track record of premium cartridge performance.
Expected page output and replacement cycles
Toner cartridge yields are calculated using the ISO/IEC 19752 standard for monochrome laser printing, ensuring clear visibility over ongoing operational expenses. The standard TN-2130 offers standard text capacity, while the high-yield TN-2150 reduces the frequency of physical swap-outs during peak office cycles.
| Cartridge Number | Type | Colour | Page Yield | Cost Per Page |
|---|---|---|---|---|
| TN-2130 | Standard | Black | 1,500 | $0.069 |
| TN-2150 | High Yield | Black | 2,600 | $0.051 |
Cost Per Page = Total Cartridge Price ÷ Page Yield (at 5% coverage). Prices based on Genuine cartridges.
Managing genuine vs compatible options
Under Australian Consumer Law, using compatible cartridges does not void your printer warranty. Choosing premium compatible alternatives provides an identical physical fit to original components, ensuring dependable office printing without impacting your legal protections.

Maintaining the separate drum unit
The separate DR-2125 drum unit dictates the physical transfer of your text onto paper and handles significantly more pages than a standard toner. Experience Tip: When replacing your drum, you must manually reset the printer counter by opening the front cover and holding down the "Clear/Back" key until the LCD prompts confirmation.
Stocking your office and delivery options
If you handle heavy administrative text printing, investing in a high-yield twin pack or compatible bundle reduces document management overheads. Ink Depot despatches orders from major logistics hubs across Perth, Brisbane, Sydney, Melbourne and Adelaide. Free delivery applies on all orders over $99 (conditions apply). We back our premium compatible range with a comprehensive money-back guarantee, accessible through our returns policy.

Pro Tip
Do not discard your DR-2125 drum unit when the toner light flashes; the printer requires approximately four to five toner replacements before the drum structure actually reaches its physical wear limit.
Frequently Asked Questions
Why is my printer still showing a low toner message after inserting a new TN-2150?
Brother laser systems rely on a physical gear reset mechanism on the side of the toner cartridge rather than an electronic chip. If the printer fails to register the new toner, removing the cartridge and manually turning the primary reset gear forward ensures the internal sensor detects the fresh supply.
Can I install a TN-2150 cartridge if my printer previously used a TN-2130?
Yes, the high-yield TN-2150 and standard-yield TN-2130 share the exact same external physical dimensions. The difference lies entirely in the internal reservoir capacity, meaning the high-yield version slots directly into the existing DR-2125 drum housing without adjustments.
How do I know whether to replace the toner cartridge or the DR-2125 drum unit?
Faded text or an explicit "Replace Toner" alert indicates the toner powder is exhausted. Conversely, horizontal black streaks, repeating vertical dots, or a specific "Replace Drum" message mean the drum cylinder is physically scratched or worn out and requires a replacement.
