Samsung CLT-W409 Genuine Waste Toner Container (HP SU430A), 10,000 Pages, for CLP-315, CLP-325, CLX-3170, CLX-3175, CLX-3185

The Samsung CLT-W409 Waste Toner Container is the genuine Samsung replacement container that collects the surplus toner cleaned off the drum and transfer system during printing, rated at 10,000 black or 2,500 colour pages, for the Samsung CLP-315/325 and CLX-3170/3175/3185 colour laser printers.

It is the part to order when your printer reports that the waste toner unit is near full or full. Samsung printer supplies are now sold and supported by HP, which is why the same container carries the HP part number SU430A.

• 1 × genuine Samsung CLT-W409 Waste Toner Container (part SU430A)

• 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 10,000 black or 2,500 colour 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 Samsung.
• 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.
