When refilling toner cartridges, we generally recommend wearing latex gloves and a fine particle mask.
Please read these instructions carefully before you start refilling.
Loosen the screws marked in picture 1 from the right side cover and lay them aside; you will need them to reassemble the cartridge afterwards. Now carefully lever the cover from the cartridge with a flat screwdriver. The filler opening is now visible (picture 2). Remove the sealing plug from the cartridge. Before you can refill the toner cartridge, you should pour out the rest of the toner powder or aspirate it with a toner powder vacuum cleaner. Otherwise, the different physical and chemical characteristics of the old and the new toner powders could lead to clotting.
Screw the funnel onto the toner bottle to facilitate refilling. Now fill the toner powder into the cartridge as shown in picture 3. Then you can reseal the opening with the sealing plug.
The cartridge is equipped with a chip that needs to be exchanged after every refill. Here, the chip is located underneath a cover that is attached to the cartridge with 2 plastic lugs (picture 4). You need to break them off with a flat screwdriver or a cutter knife. Then remove the cover and the old chip. Put the new chip in the same position as the old one and put the cover back in place. Fix the cover with a small drop of glue or double-sided adhesive tape. Once the chip is replaced, your printer recognises the cartridge as full. Please refill toner powder as well to achieve the full printing capacity of the cartridge. The cartridge Samsung ML-2850, ML-2851, ML-2855, SCX-4824 is now refilled and you can reinsert it into your printer.
Refill toner and toner powder may cause serious health problems if not handled carefully. We recommend always using breathing protection or suction chambers while filling toner cartridges. Furthermore, toner powder and refill toner can be highly flammable with an appropriate oxygen mixture. Please note as well, that you should touch the photoconductor drum in no case or expose it to direct sunlight. This could lead to faulty print-outs. Octopus Office will not take any responsibility for success or failure of the described procedure.
