Genuine magenta toner for high-volume colour

The Brother TN439M is an original ultra high yield cartridge rated for approximately 9000 pages. It supplies magenta toner for compatible Brother colour laser printers and multifunction devices. Offices and workgroups that produce large volumes of colour documents will find the capacity matches their throughput needs. Buyers who require cyan, yellow or black toner must purchase those cartridges separately.

Passive consumable with no active cooling or power

The cartridge contains only toner powder and mechanical components; it generates no heat, emits no noise and draws no electricity during printing. Thermal management, acoustics and power consumption are handled entirely by the host printer. There are no fans, radiators or electrical connections on the unit itself. Users who expect active cooling or power regulation from a supply item will not find it here.

Sealed single-unit design installs directly into

Supplied as one sealed cartridge, it fits the designated magenta slot in the HL-L9310CDW and MFC-L9570CDW series without additional brackets, cables or adapters. The moulded housing protects the toner from spillage during handling and storage. No separate waste container or maintenance kit is included with this item. Customers needing a multi-pack or a starter-capacity cartridge should look for a different SKU.

Questions about this item

How do I install the TN439M cartridge in a Brother HL-L9310CDW?

Open the front cover, pull the drum unit assembly out, press the green lock lever on the magenta slot to release the old cartridge, unpack the new TN439M, remove its protective cover, slide it in until it clicks, then reinsert the drum unit and close the cover.

What other parts will need replacing after the TN439M runs out?

The drum unit (DR-439CL) and waste toner box (WT-320CL) are separate consumables; each has its own life counter and the printer will prompt when they need changing.

At what page count should I expect the toner to run low under continuous printing?

The cartridge is rated for approximately 9000 pages at 5 % coverage; heavy graphics or solid fills will reduce that figure, while lighter text may extend it.
