Brother WT-320CL Genuine Waste Toner Unit, 50,000 Pages, for HL-L8260CDW, HL-L8360CDW, MFC-L8690CDW, MFC-L8900CDW

The Brother WT-320CL Waste Toner Unit is the genuine Brother replacement container that collects the surplus toner cleaned off the drum and transfer system during printing, rated at approximately 50,000 single-sided A4 pages, for the Brother HL-L8000/L9000 and MFC-L8000/L9000 colour laser series.

It is the part to order when your printer reports that the waste toner unit is near full or full. Offices that already stock toner for these models should keep one of these alongside, because a full waste unit stops the printer just as surely as an empty toner cartridge does.

• 1 × genuine Brother WT-320CL Waste Toner Unit (part WT320CL)

• The printer counts what goes into the unit and warns you when it is nearly full; once it is full, printing is blocked until a new unit is fitted, so ordering at the first warning avoids downtime.
• Rated approximately 50,000 single-sided A4 pages. Real life depends on your coverage, the mix of colour and mono pages, job length and how often the printer runs calibration and cleaning cycles — short jobs and frequent colour calibration fill it faster.
• Replacement is a user task on the listed models: the unit is accessed from the printer, the full one is removed and the new one clicked in, with no tools or service engineer needed.
• A full unit holds loose toner powder. Keep it upright, seal it (the new unit's packaging is ideal) and recycle it.

• Printers that are not on the compatibility list below — waste toner units are shaped and chipped for specific engines and are not interchangeable between series, even within Brother.
• It is not a toner cartridge, drum or transfer belt: it adds no toner and will not fix faded, streaked or blank prints on its own.
• Emptying and refitting a full unit — it is a single-use consumable; reusing it risks toner spilling inside the printer and the printer may still report it as full.
