Brother TN730 Black Toner Cartridge: what it fits, yield and what to check

The Brother TN730 is a replacement black toner cartridge for a specific group of Brother mono laser printers and all-in-ones. It's a consumable part: when the toner in your printer runs low, this is the cartridge that goes in. Here is what it is rated for, which printers it fits, and what to confirm before ordering.

What the TN730 is

Brother describes the TN730 as a genuine, standard-yield cartridge, meaning it's made by the printer's own manufacturer rather than a third party. It prints in black only and is intended for laser printing, where toner (a fine powder) is fused onto paper with heat. Brother says it produces crisp, sharp prints with rich blacks and is engineered to work with its printers.

Page yield explained

The listing says the cartridge prints approximately 1,200 pages. Yield figures are given under the ISO/IEC 19752 standard for Letter and A4 paper, which uses a defined test page so cartridges can be compared fairly. Your own results will typically differ. Pages with dense graphics use more toner than text documents, and printing many short jobs can use slightly more than long runs.

Which printers it fits

Brother lists nine compatible models:

• DCP-L2550DW
• HL-L2350DW
• HL-L2370DW and HL-L2370DW XL
• HL-L2390DW
• HL-L2395DW
• MFC-L2710DW
• MFC-L2750DW and MFC-L2750DW XL

The printer model is normally printed on the front or on a label, and it's worth matching it exactly. Toner cartridges are specific to model families, and a similar-looking number such as TN760 is a different, higher-yield cartridge. Always compare the full model name with the list above.

Automatic reordering

Brother says the TN730 works with an automatic replenishment service on eligible printers. When the service is activated, a compatible printer can order supplies on its own when toner runs low. This is optional and depends on your printer and account, so check Brother's own information on whether your model is eligible.

Disposal

Brother states that it is committed to environmental responsibility and offers disposal programmes for used cartridges. Programmes vary by region, so check Brother's website or your local recycling guidance for what's available where you live.

Who it suits

The TN730 suits home offices and small workplaces that print mostly text in black and white on one of the listed Brother printers. Because it's the standard-yield cartridge, it's a sensible fit for lighter print volumes. Heavier printers may want to look at whether a higher-yield cartridge exists for the same model.

What to check before you buy

• Exact printer model: match your printer to the nine models above, including suffixes like XL.
• Cartridge number: confirm it says TN730 and not a related number.
• Colour: this is black only; colour laser printers use separate cartridges.
• Yield: about 1,200 pages is a test-based figure, so your real use may vary.
• Drum unit: in many Brother laser printers the drum is a separate part from the toner. Check your manual for which part needs replacing.
• Fitting: follow the printer manual for removing the old cartridge and installing the new one.
