The Samsung MLT-D104S is a compact and highly popular toner cartridge used in series like the Samsung ML-1660, ML-1665, ML-1860, and the SCX-3200 MFP. While these printers are incredibly reliable, the 104S cartridge features a unique sealed design using plastic rivets, which can make DIY maintenance seem challenging.
In this guide, we will demonstrate how to successfully refill your toner and replace the OPC drum to restore factory-quality printing.
Refill and Drum Replacement Steps
- Opening the Sealed Housing: Unlike other brands, the MLT-D104S is held together by plastic rivets. First, you must carefully remove or drill these rivets to access the internal components. We show the safest method at.
- Cleaning the Waste Toner Bin: Subsequently, separate the waste section from the toner hopper. It is vital to empty the waste toner to prevent background shading or grey streaks on your pages.
- Replacing the OPC Drum: If your prints have physical scratches or repetitive black dots, you must replace the green OPC drum. This is the most effective way to “reset” the mechanical quality of the cartridge.
- Refilling the Hopper: Pour in high-quality specialized Samsung monochrome toner powder. Consequently, ensure the hopper is clean before refilling to avoid mixing different toner formulations.
- Smart Chip Installation: Finally, you must replace the reset chip. Note: Samsung chips are region-locked. Ensure you use the XIL chip for Europe, XAA for North America, or XSS for Asia to avoid “Incompatible Toner” errors.

Expert Tip: Regional Codes & Reassembly
When reassembling the cartridge, replace the drilled-out rivets with small self-tapping screws. This makes the next refill significantly easier. Furthermore, always verify your printer’s region before buying a chip. If your printer was purchased in Europe, an “XAA” (USA) chip will not work, even if the toner powder is identical.
